More details are surfacing regarding Timothy Smith, the shooter who killed four people at a Pennsylvania car wash over the weekend. According to police, the 28-year-old was armed with a semi-automatic rifle, a .308-caliber rifle, and a handgun when he opened fire on Ed's Car Wash — a business located 55 miles outside of Pittsburgh.

Now, family members of the victims are coming forward and revealing that Timothy, who is currently on life support after suffering a self-inflicted gunshot wound to the head, was driven by jealousy. Turns out one of the victims, Chelsea Cline, briefly dated Timothy and her half-sister, Sierra Kolarik, told the Pittsburgh Tribune-Review that he had developed an obsession with her.

Timothy also shot and killed William Porterfield, 27, and his pregnant wife, Jenna, admitted to the Pittsburgh Post-Gazette that a police investigator admitted to her that Timothy was a "jealous former boyfriend." She also explained how there were rumors her husband was cheating on her with a woman who had just broken up with her boyfriend — seemingly Chelsea. “I was told my husband was cheating on me with [one of the victims], and that she had broken up with her previous boyfriend two days ago, and he went crazy and shot them all,” she said. “I’m not holding that against Will. We weren’t fighting. We were fixing. And if he was with someone else while we were having problems, honestly, I don’t care what he did. I’m not going to hold that against him. I’d give anything to have him back."

Along with Chelsea and William, Timothy also killed 23-year-old Courtney Snyder and Chelsea's half-brother Seth Cline, 21. "You always had fun when you were around him," family friend Cayleigh Myers said of Seth. "He would give his shirt off his back for you, anything, it didn't matter what it was, what time it was, if you need him, you could call him. He was everything."

A neighbor is said to have heard 30 shots go off during the attack and one unnamed woman suffered minor injuries from broken glass after taking cover in a truck during the shooting. Timothy is not expected to survive his injuries. So far this year, there have been 22 mass shootings in the United States. Reminder, it's only January.
