Authorities have released a photograph of Roberts, 22, who wore a hockey-like face mask and opened fire on holiday shoppers Tuesday at the Clackamas Town Center in Happy Valley, Oregon, near Portland. He killed two people and then himself. The photograph of Jacob Tyler Roberts depicts someone in tune with the latest fashion trends. He sports a thin chin beard and grommet earrings embedded in both lobes. Black, wavy hair frames a half-smile and almond-shaped eyes. One of his Facebook friends, Brittany Curry, 21, told CNN she dated Roberts for five months last year. They met through mutual friends in the Portland area, she said. "I am in shock. I don't know what to feel," Curry said in a telephone interview. "He was really a good guy. He was really happy. He put everybody before himself." Roberts owned one gun, Curry said, but she didn't want to elaborate. His Facebook page lists "shooting" as one of his 10 interests, along with camping, sleeping, rafting, BMX, sushi and spending money.

Roberts wrote on his Facebook page: "My friends are my family and I don't think that will ever change. I have done a lot for myself in the past year some good and some bad but I still press on. "I like hanging out with my friends and having a good time maybe get a little drunk every now and then. I like to think of myself as a bit of an adrenaline junkie... Yup that's right I'm a junkie lol. But I'm just looking to meet new people and see the world," Roberts typed. When they were dating, Roberts was living in an apartment across from the Clackamas Town Center mall, Curry said. Roberts wanted to be a firefighter and was taking classes at Clackamas Community College, Curry said. "It was always his dream," Curry said. In the meantime, he had been working as a cook at Big Bertha's gyro eatery in Portland for more than two years, Curry said. About that job, Roberts commented on Facebook: "Right now I work at the most badass gyro shop in town. I am one of the few people that can say I love my job and actually mean it."
