CANADENSIS (AP) Every time Tiffany Frein logs on to Facebook, she sees people calling her brother a "psycho" who should be hunted down and killed.

"It's hard and it's hurtful," the 18-year-old said."People just automatically think he's a psycho."Standing in the doorway of her family's home in the Pocono neighborhood Thursday, Tiffany Frein looked out at her driveway and ran her fingers through the pink streaks in her hair.Her brother, Eric Frein, is the suspect in a shooting at the Blooming Grove barracks Sept. 12 that left one trooper dead and another seriously injured.Police launched an expansive search for the 31-year-old Canadensis man last week, and Frein has seen her brother's face on billboards, television and the Internet."I don't think it's really hit me yet," she said of the shooting. "That's not my brother. That's not something I can see him doing."While her brother mostly kept to himself at home, Tiffany Frein said he would gladly open his door if she wanted to talk."I'd knock on the door and we'd talk," she said. "When the family was fighting we'd talk just, 'Oh, you know how Dad is,' kind of stuff."When he came out of his room, he would get a cup of coffee, a snack and maybe watch some TV."Despite their age difference, Tiffany Frein said she had a close relationship with her brother."We used to be close," she said. "But we got into a fight in July, and I haven't spoken to him since. ... It's hard that he's not here."State police searched the Frein home last week.At a press conference Thursday, state police Commissioner Frank Noonan said the Frein family has cooperated with the ongoing investigation and search for the suspected gunman."There's one person that committed a crime; it's not contagious to his family," he said. "I'm sure they're as heartbroken as anybody."Frein allowed police to search her bedroom. She came home Thursday looking for a clean pair of tights."I have to go clean my room now," she said.
