ROSEBURG, Ore. (AP) - Social media profiles linked to a 26-year-old shooter who killed at least 9 people at a southern Oregon college suggested he was fascinated by the IRA, frustrated by traditional organized religion and tracked other mass shootings.

There didn't seem to be many recent connections on the social media sites linked to Chris Harper Mercer, with his MySpace page just showing two friends. He appeared to have at least one online dating profile.

On a torrents streaming site and blog that appeared to belong to Mercer, posts referenced multiple shootings and downloads included several horror films and a documentary on a mass shooting at Sandy Hook Elementary School in Newtown, Connecticut.

A blog post urged readers to watch the online footage of Vester Flanagan shooting two former colleagues on live TV in Virginia, while another lamented materialism as preventing spiritual development.

A MySpace page that appeared to belong to Mercer included several photos and graphics of the Irish Republican Army as well as a picture of Mercer holding a rifle.
