Officials tell Channel 6 News the teenager arrested over the weekend for the murder of an elderly Omaha man is on suicide watch in jail.

Nineteen-year-old John Runnion of Omaha was booked for first-degree murder in the death of 71-year-old Patrick McAndrews, whose body was found in his apartment at 60th and Spring streets on Saturday.

Friends found McAndrews after not hearing from him in days.

Officers noticed McAndrews' car keys and blue Honda Civic were missing. The car was stopped Saturday in the area of 108th and Maple Street, driven by Runnion.

At work Sunday, Mark Majors heard the news about a friend and co-worker. "I thought it was joke because I didn't see it personally and then someone came back and told me and I came up and saw his face on TV for first-degree murder, that's pretty crazy."

The face Mark saw was that of his friend and Burger King co-worker, John Runnion.

"I believe he did have a car,” says Majors. “Actually he didn't have a car, then I saw him with a car one day." That was one night last week and the car was a blue Honda Civic. "I asked him where he got a car, he just said he just bought it, that's all he told me," says Majors.

"He was kind of creepy,” says Runnion neighbor Kristin Schafersman. “He didn't really talk, but he would just kind of stare at you when you'd walk by and never really say anything.”

The victim's neighbors are still reeling from the news. "I was shocked to hear that he had died and then to hear they suspected foul play,” says Jessica Reese. “It was kind of crazy."

McAndrews' neighbors said they hadn't seen Runnion before. They said McAndrews frequently picked up people in need from shelters and paid them to come and clean his apartment. They think, perhaps that's how the two may have met.

The cause of death has not been released. All police will say is that an autopsy confirmed it as a homicide.
