Robert "Bobby" Gladden's last post, made via mobile on Monday morning before school started, reads "First day of school, last day of my life. t(~_~t), f**k the world."

He has two profile photos on his timeline: one in which his long, black hair is pulled down over his face and another of  German musician Til Lindermann-Rannsteinhe sneers looking at the camera wearing a collar.

Bobby Gladden's Facebook likes include the TV show "Happy Tree Friends" and "South Park." He is a fan of pro football player Bob Sanders. In his photo album, a picture taken at McDonald's with a long straw coming out of a cup on the floor and the caption "I made a super straw :3"

But there is also a dark side to his Facebook profile. He lists "Eric HARRIS and Dylan KLEBOLD," the gunmen in the Columbine shooting, as inspirational people along with Til Lindermann-Rannstein, a German musician. His favorite books includes  the biography "Charles Manson, Coming Down Fast."

Robert Wayne Gladden lists his place of birth as Leipzig, Germany and his marital status as divorced.

Many students and parents were aware of the posting and cited it when talking to the media following the shooting.

Gladden's father told The Associated Press that his son had been bullied, although he did not provide details. A woman who was also at the home in Middle River and said she was related to the elder Gladden gave the following statement on the family's behalf: "We are horrified. We did not see this coming and our thoughts and prayers are with the victim and the victim's family."
