Family friends of the Clackamas Town Center gunman say up until the day of the shooting, Jacob Roberts showed no signs he was depressed, or troubled.
Jaime Eheler, Roberts' closest friend and roommate, says he was planning to move to Hawaii and had sold all of his belongings two weeks ago.
Eheler says it wasn't until Tuesday he told friends those plans had changed.
"This is all just so difficult," said Eheler.
"He had this look on his face, and I asked him what going on, and he told me he was going to go help out a friend, and that he'd talk to me when he got home, I assumed he was coming home."
From there, Eheler says, Roberts drove to her brother's home to say goodbye.
"He told my brother he wanted to go somewhere south, somewhere warm, and then he gave him a bracelet. He said he was heading out and that he didn't really want to go, but he had to, things just weren't working out for him," said Eheler.
Not even an hour later, Roberts opened fire inside of Clackamas Town Center, and then turned the gun on himself.
Eheler says she'll never understand it. She's looked for a note hidden somewhere in their home, but can't find one.
What she did find though, shocked her.
"I walked downstairs, his bedroom is in the basement of our house, and there were bags and boxes of empty bullets, and there was some kind of cut up gun holster thing sitting next to laptop," said Eheler.
Roberts' biological mother died of cancer when he was young, something that Eheler said was hard for Roberts. His aunt Tami raised him until he was teen, who told FOX 12 they had a falling out four years ago.
"He didn't want to get up and look for a job. His whole purpose in life had changed and he got really depressed and really angry and I don't blame him," said Tami Roberts.
But friends say that falling out was because Tami Roberts spent money Jake Roberts inherited from his mother.
Jake Roberts moved in with Eheler and her family at the age of 17.
Eheler says while they may never know what triggered him to snap, they're hopeful one day they'll find a way to understand .
"I'm not too sure on what happened to make him do this, this isn't who he is, he doesn't hurt people," said Eheler.
