TUCSON, AZ - Zach Osler sobbed as he looked at 22-year-old Jared Loughner's piercing stare in a jail house mug shot.
"It's hard to look at the picture of him," cried Osler who said he and Loughner were close friends in high school. "He looks like a monster ... it scares me"
"He wasn't shooting at people; he was shooting at the world," Osler said in an exclusive interview with ABC's Ashleigh Banfield.
Osler described how the two friends hung out, but he never felt comfortable at the Loughner home.
"The house itself is kind of shrouded, it's kind of covered up, like cold," Osler said. "Cold, dark, unpleasant. I always felt unwelcomed, like I shouldn't be there."
Osler said he started to see a change in Jared Loughner after a high school sweetheart broke up with him. After that, Osler said Loughner became increasingly angry and started abusing alcohol, drugs and the legal herbal hallucinogen called Salvia.
"He would say he would be using it, and talk about what it would do to him, and I would say 'dude, that's, that's screwed up,'" said Osler.
Soon after, the former friend says they lost touch but he wonders if things could have been different.
"I just forgot about him, you know. We stopped talking to each other. I wish there was something I could've done or said that helped him or tried to get him out ," a crying Osler said.
