(AP) AURORA, Colo. - Authorities are insisting that the suspected gunman in the Colorado theater shooting acted alone — even as they interview people they believe may have associated with him.
FBI spokesman Dave Joly said late Saturday the federal agency "is not looking at a second suspect" in the Friday massacre in Aurora, Colo.
Aurora Police Chief Dan Oates says "there is absolutely no question that this guy acted alone."
Oates spoke after a Denver TV station reported that police were looking for a second person of interest.
The station cited unidentified sources as saying the person was classmate of shooting suspect James Holmes.
Oates says police are talking to many people and that investigators "are trying to track down a classmate of his, but that's all this is."
