Catch my Killer

This week I interviewed David Keck, a gay man from Tennessee who shouldn’t even be alive to be speaking to me. It’s actually an act of God that he’s even alive. In 2014, David had met with some friends at a bar called Bullfeathers located in Knoxville, Tennessee. The friends had gotten together to have some drinks and participate in Karaoke. While on his way to the restroom, a man unknown to David engaged in a brief conversation with him. David said he believes they were discussing neck ties because David designed custom neck ties at the time. Thinking the man was interested in purchasing neckties, David gave the stranger a business card.


David then went back to his friends and thought nothing else about the stranger. David then left the bar before closing and drove home. Shortly after arriving home, he heard a knock on the door. It was the stranger at the bar. He had followed David home. Moments after opening the door, everything went black. The stranger physically assaulted David and raped him.


David was beaten so bad, his attacker assumed he had killed David. He would end up confessing to the mother of his children that he had murdered a gay man. He also stopped at another bar and told patrons he had killed a gay man. Eighteen hours later, the police arrived at David’s apartment. They found his apartment walls and floors covered in blood. The police officers that arrived looked at David’s body in a pool of his own blood. They assumed he was deceased until they saw his foot move.


The man who nearly killed David was eventually arrested and charged with assaulting David. For unknown reasons, he wasn’t charged with a hate crime. David is also a podcaster who has a show called Surviving Abuse where he speaks to survivors of horrific events. To learn more about David and his podcast, visit his website at https://survivingpodcast.com/ or you can find his Surviving Abuse podcast on all major platforms.


Just remember that you are not alone and if someone sexually assaulted you, it’s not your fault. You are a victim. If you need to speak to someone, you can call the National Sexual Assault Hotline at 1-800-656-4673.

This week’s story is about , a 20-year-old woman who vanished in January 2020. On January 9, 2020, Kaylene Oehling, 20, was last seen in Etna, Pennsylvania. She left home to meet her boyfriend, Mike Manno, but did not return. At 1:36 a.m. on January 10, she texted her mother to confirm she'd see her in the morning as she had plans to babysit her younger siblings while her mom worked. She never showed up and has never been seen again.


Manno is considered a prime suspect in Oehling's disappearance. However, he claims she is alive and had been in touch with her. He claims to know where she is, but refuses to tell police where or cooperate with them. He has a lengthy criminal record which includes convictions for arson, theft, auto theft, statutory sexual assault, reckless endangerment, corruption of minors, and aggravated assault. He is currently behind bars.


In the days following Kaylene's disappearance, Manno sent explicit photographs of Kaylene to both her father and her 17-year-old sister. Manno has since been charged with corruption of minors. In addition, Kaylene wrote on her Facebook account that Manno had committed a robbery. In less than an hour, Kaylene's Facebook account was deactivated. This would be unusual behavior for Kaylene because she was highly active on social media.


For this story, I spoke with Kaylene's father, Jason Oehling, who is retired but has dedicated himself to finding out what happened to his daughter and advocating on behalf of other missing people. Now on with the story of Kaylen Oehling as told by her father Jason.


To report information about Kaylene Oehling's disappearance, please contact the Allegheny County Homicide Unit at 412-473-3000. You can also learn more about this case by visiting the Missing Kaylene Oehling Facebook page.

This week’s story is about a man in his 20s named Michael McKenney who lived in the Fairfield, Ohio area with his aunt and her family. For this story, I spoke to his mother Yolanda Middleton who has been searching for her missing son since May 2020 when he disappeared from a local park.


Michael was a young man who had internal demons he had to battle. He had a drug issue and had previously overdosed. But his mother said he seemed to be on the right track when he disappeared. He had just purchased a new car and had two jobs.


Michael vanished from Hueston Woods in Butler County, Ohio. Fairfield Township Police consider the case an active and open one. Unfortunately, they have run out of leads and haven’t been able to locate Michael or figure out what happened to him. Yalonda has hired a private investigator, passed out flyers, talked to local media about Michael and has done a lot to keep her son’s name in the public.


What happened to Michael nearly two years ago? His mother and siblings need answers. They would like to bring Michael home and to find out what happened to him. His family has been searching for him for nearly two years. They are concerned about his welfare and want him to come home.


If you know anything about the disappearance of Michael McKenney, please contact the Fairfield Township Police at 513-887-4406. Or you can also contact Private Investigator John Sain, at 937-974-6026. You can also learn more about this case by visiting the Bring Michael Home Facebook page.

This week’s story involved A 37-year-old woman named Tina Mae Duffell who was murdered on October 17, 1974. She worked part time at a convenience store in Quapaw, Oklahoma, where she was abducted, killed, then found in a pond.


Michelle Blank, Tina's daughter, still hopes Oklahoma authorities will find out who killed her mother. At the time of her mother's abduction, Michelle was a teenager. She was the last person to see her mother alive. Michelle stopped by the convenience store to see her mother. While in the store, she noticed a tall man with dark hair drinking a soda.


Little did Michelle know that the man she saw inside the store and another man would take her mother from the store and kill her. The Oklahoma State Bureau of Investigation has looked into the case. Unfortunately, there are still no answers.


Do you know what happened to Tina? Her daughter Michelle Blank remains distraught over her mother’s death. She doesn’t know who killed her mother or why. Although it’s been nearly 50 years since her mom died, she realizes the killers may also be deceased by now.

This week's story focuses on a 19 year old Houston, Texas man named Alexander "AJ" Silva III. His relatives say the last time they saw him was either April the 5th or 6th of 2021. Nearly a year has passed since anyone has heard from Silva. Friends and family say there is a reason for this. Although AJ's case is considered a missing person's case, his family claims that he is deceased.


Silva was charged with felony retaliation. As part of his bond conditions, he was ordered to wear an ankle monitor. The family assumed since AJ had a monitoring device, then law enforcement would always know his whereabouts.


However, they would learn this wasn't the case because law enforcement wasn't always monitoring him. He would eventually disappear and neither his family nor law enforcement know where he is. For this story, I spoke to Paul Vasquez, who is AJ's uncle. After being frustrated with law enforcement's efforts, Paul has traveled between his New Mexico home and Houston to perform his own investigation into his nephew's disappearance.


Paul found a young woman who witnessed someone chase and shoot AJ to death. She even showed Paul where AJ's deceased body lie after he died. Paul recorded the woman's statement and shared it with authorities. According to Paul, the Houston Police Department have discredited the witness. However, Paul believes her because she had nothing to gain by lying and he felt she risked her life to share this information.


Paul has since interviewed many witnesses and has pieced together the final days of his nephew. He told me he doesn't have a good relationship with Houston PD and they will no longer speak to him. At this point, he has said he just wants justice for his nephew and for police to acknowledge that AJ is not a missing person but indeed deceased.


The family is determined to find out what happened to AJ. They are worried that law enforcement will not give this case attention because he is a young black man with a troubled past. According to AJ's electronic monitoring records, he was at a warehouse on Lumberdale Road in Houston. And it's this warehouse where a witness told Paul Vasquez she witnessed AJ's homicide.


If you know what happened to AJ Silva III, please report your tips to the HPD at (713) 884-3131. And if you would like to know more about this case, please visit the Justice for AJ Facebook page. There is also a Tik Tok account with even more information. The address is @justice4lilaj

This week's story focuses on a Pennsylvania teenager named Alicia Markovich who was 15 when she vanished on April 26, 1987 from Dunn Avenue in Blairsville, Pennsylvania. At the time, she was visiting with her father John Markovich. This year will be the 35th year anniversary of Alicia's disappearance. Unfortunately, Alicia's mother, Marcie Smith, has long given up hope that she will ever see her daughter alive again.


The day seemed like any other day. Alicia, an eighth-grader at Windber High School in Somerset County, left with her father to spend time with him at his Blairsville home. Alicia's parents were divorced. It wasn't an overnight stay. Alicia was supposed to return home that same evening.


Supposedly, Alicia and her father got into an argument around 5pm. Allegedly, Alicia stormed out of the house and has never been seen again. She is listed as a missing person with state police and the National Center for Missing and Exploited Children. But everyone who was close to Alicia don't believe she is alive.


For this story I spoke to Chrissie Boyer, who was Alicia's childhood friend. Chrissie is one of Alicia's advocates and is also close friends with Alicia's mother Marcie. I also spoke a Laura Valdez, who has been friends with Marcie since childhood. She knew Alicia from birth and used to take Alicia out for pizza when she was a child.


I also reached out to John Markovich and his wife and asked them to participate in this episode. Neither responded to my request. I also want to state that many people think John Markovich knows more about his daughter's fate than he has ever said publicly. However, I must state that no criminal charges have ever been brought against him and he must be considered innocent of any wrong doing in the eyes of the law.


If you know what happened to Alicia Markovich, please contact Pennsylvania Crime Stoppers anonymously at 1-800-472-8477 or the National Center for Missing and Exploited Children at 1-800-843-5678. You can also visit www.justiceforaliciamarkovich.com for additional information about Alicia's story.

In July of 2006, Shawn O'Brien was a 34 years old carpenter who didn’t show up for work on Saturday, July 22. Around 6 o'clock that night, his sister called 911. She had found him lying in a pool of blood on the floor of his Pleasant Street basement apartment. First responders weren’t sure what happened to Shawn. They believed he had possibly had a seizure. Did he fall and hit his head? The police didn’t consider the basement a crime scene so they didn’t close it off immediately and investigate it.


Police would come back at a later time to investigate the basement. The autopsy would be inconclusive but ruled that O’Brien had blunt force trauma to his head. And it didn’t seem likely it came from a fall.


“This is a classic sign of somebody being assaulted,” said Dr. Timothy Gallagher, an independent forensic pathologist. Gallagher also said, he cannot with one hundred percent certainty rule out that it was an accident, because there are no witnesses to corroborate what exactly happened in his final moments.


But, Gallagher does not believe O’Brien just fell to the floor. “Most likely not,” he told the NBC 10 I-Team. “When a person does fall, their injuries are just one-sided, they do not hit the ground and turn over and hit the ground again and turn over and hit the ground again. They hit the ground once, creating one injury,” said the forensic pathologist.


The police have two persons of interest. A man named Armand Rouleau rented the apartment to O’Brien. The other person of interest is Armand’s then girlfriend, Lynn Hallal.


Today, Natalia St. Louis is no longer a teenager. She is an adult who is determined to find out what happened to her father 15 years ago. Please be sure to visit Today, there are no answers about Shawn’s death. Natalia St. Louis is offering a $1,000 reward for information leading to an arrest in her father’s case. She has a Facebook page titled “Justice for Shawn O’Brien.” And if you know anything about Shawn's death, you can contact the Cranston Police Department at 401-942-2211 with your tips.

This week's story focuses on Amy Jo Nelson, a young mother from New Straitsville, Ohio who died on Sept. 18, 2017. It was initially thought she died of a drug overdose. On her death certificate, however, it stated that she died as a result of a homicide.


According to the Perry County coroner's report, both prescribed and non-prescribed drugs were in her system. However, drugs did not cause her death. The autopsy findings indicated Amy Jo Nelson's death was a homicide caused by blunt force trauma to the head."


"The extensive head and brain injuries are not consistent with a simple fall and are consistent with injuries incurred by multiple blunt force trauma. Given the other body injuries, it appears the decedent was assaulted by another person or persons. Abbie Vann, Amy's sister, and Pam Nelson, Amy's mother, say that they are haunted by Amy's death and relive it each day.


Amy's family has conducted their own investigation. They have done the legwork, obtained statements and documented their findings. Although they believe they know who killed Amy, they don't have any evidence to support it. Family members put out a reward in the hopes that someone will provide a tip that will lead to the murderer's arrest.


According to Pam Nelson, Amy's mother, "We have our ideas of what happened based on the information that we've been given and the facts that we have, but not knowing the exact truth to have some sort of closure for our family trying to relive it every day and thinking of all these different possibilities of things that have happen, it's really hard,"


What happened to Amy Jo Nelson? She was a mother, sister and daughter. Family members miss her. If you have any information about this case, call Perry County's tip line at (740) 721 - 0898. You can also visit Amy's Facebook page titled Amy's Gift of Hope. The family is still offering a reward for information.

I spoke with a mother named Jennifer VanDalsen about her son Alex VanDalsen, a twenty-one-year old, who died under mysterious circumstances. Alex was born Jasmine Mckenzie Danaher, but planning on transitioning into a man. Therefore, I will refer to him as Jennifer's son throughout this story. At 15, Alex decided he knew he was a male and wanted to live as one. Throughout this episode I'll refer to the victim as Alex and use male pronouns. He lived in Lafayette, Indiana.


On February 3, 2021, it was a cold and snowy Indiana evening. Alex left home before midnight for unknown reasons. He did not tell anyone where he was going. On February 9th, two thousand twenty one, Alex was found dead. His death was ruled a suicide without any investigation.


Alex's family has taken issue with the ruling. Police told Alex's family that "There was no immediate sign of trauma on the body." However, it wasn't until Alex's body arrived at the funeral home that they discovered he died from a gunshot wound to the head. The family asked the detective why he said there was no trauma to the body when there was a gunshot wound?


It was less than twenty degrees when Alex was found 10 miles from his home. He also had asthma and wasn't dressed for the weather. Such treacherous weather would have made it impossible for him to walk ten miles. He would have died from exposure. Alex's family is certain he met with someone who knows what happened to him.


The family also had a concern about the actual bullet wound. I was informed the entrance wound was larger than the exit. As someone who fired weapons in the military, this isn't feasible. The exit wound is typically larger when leaving the human body.



The family also said Alex wasn't tested for having gunshot residue on his hands and the weapon wasn't checked for fingerprints. Also, Alex didn't own a gun, so where did this gun come from and who owned it?


There were also no shell casings. How could Alex kill himself with a gun and not leave a shell casing behind? And there was no blood splatter at the scene. If Alex killed himself, there would be a casing and blood present at the scene. Most likely Alex was picked up by someone, shot to death and then dumped where he was found. Unfortunately, law enforcement hasn't waivered from the suicide ruling.


Do you know what happened to Alex? Who did he go to meet on the night of his death? How did he end up dead 10 miles near his home? Supposedly, he killed himself. Problem is there were no shells or blood evidence. If have any information regarding Alex VanDalsen, please contact the Tippecanoe County Sheriff sheriff's department at 765-423-9388. And if you would like more information about this case, please visit the Justice for Alex Blake VanDalsen Facebook page.
