March 15, 2000. Jacksonville, Florida. After completing her shift at a hospital pharmacy, 27-year old Tina McQuaig drives out of the parking garage, but she never returns home. Four days later, Tina’s abandoned car is discovered in a Wal-Mart parking lot. In December 2002, Tina’s remains are discovered in a wooded area on the property of a decommissioned naval base and it is determined that she was the victim of a homicide. Suspicion eventually falls upon a former neighbour of Tina’s, as she had allegedly been conducting an extramarital affair with this man, but there is no evidence to implicate him and the crime remains unsolved. On this week’s episode of “The Trail Went Cold”, we explore the unsolved murder of Tina McQuaig. In addition, we will also be discussing the murder of 35-year old Mary Petersen, who was strangled to death inside her home in Jacksonville in May 2002.

If you happen to have any information about the murders of Tina McQuaig or Mary Petersen, please contact the the Jacksonville Sheriff’s Office at (904) 630-0500 or the First Coast Crimestoppers tipline at 1-866-845-TIPS (8477).
