"Hello, I'm here to inspect the plumbing in your boiler room and bathroom."
At around 5:40 p.m. on May 19, 2014, the doorbell rang at the fourth-floor apartment in the southeastern city of Daegu. The voice on the intercom was young.
He said there was a problem on the eighth floor and that building-wide inspections were underway.
The check would take no more than 10 to 20 minutes, he added.
The door opened. Inside was a married couple in their 40s and 50s.
The purported plumber walked into the bathroom connected to the couple's bedroom, looked around and left. About 40 minutes later, at around 6:20 p.m., he returned. He said more work was needed.
"The repairs are taking a while," the 48-year-old woman said.
Moments later, the man sprayed black spray paint into her face. He stabbed her in the head and struck her with a hammer.
Her husband rushed in. Panicked, he tried to flee, reaching the front door. The attacker caught him , beat him with a hammer and stabbed him.
Both were dead at the scene.
The abusive ex
The man disguised as a plumber was Jang Jae-jin, 25, a university student in Daegu. After killing the couple, he picked up the woman's phone and sent a message to her daughter, urging her to come home early. The daughter was his ex-girlfriend.
At school, Jang was known as a capable and outgoing student. He led a club and served as president of the university's club association. In early 2014, he began dating the daughter, a 19-year-old first-year student who had joined his club. Their relationship lasted about two months, from Feb. 14 until April.
The young woman decided to end the relationship after learning that Jang had spoken about her behind her back to one of her friends.
"Why did you talk about me to my friend?" she asked.
Jang then slapped her — at least five times, according to the court.
When she stopped answering his calls and refused to meet him, he began following her.
One day on campus, he found her and demanded that she go with him to a taxi stand so they could go to his home. When she refused, he hit and kicked her. He dragged her to his house and continued beating her. Her injuries required three weeks of medical treatment.
Her parents soon learned of the violence. They contacted Jang's parents. Word spread at school, and Jang was stripped of his position as president of the club association.
Enraged by his removal, he went near his former girlfriend's home to protest. He did not see her. In later testimony, Jang said that after learning that the parents had contacted his own family about his attempts to reach their daughter, he decided to kill them.
The plot
On May 10, 2014, Jang began planning the crime. He wrote down how to enter the apartment and where to find the tools he would need. He prepared black spray paint, knives and a bag of flour to soak up blood on the floor. He packed disinfectant for himself and spare clothes.
On May 19, he returned to the apartment disguised as a plumber. He had even written a script in his notebook, detailing what to say at the door.
After the murders at his ex-girlfriend's home, Jang took two bottles of soju from the refrigerator and drank them. He then sent KakaoTalk messages to the daughter, posing as her mother and asking her to come home early.
She arrived after midnight.
As she entered, she screamed when she saw her father bleeding in the living room, his body covered with a blanket. Jang grabbed her by the hair and dragged her into a room, telling her that both of her parents were still alive. As he held her there, he spoke at length ab...
