One of KIRO 7's sister stations, Boston 25, obtained images from inside the gunman's hotel room. Weapons and a hammer are seen on the floor.
Without evidence, Islamic State claimed responsibility for the attack, and the group said the shooter converted to Islam months ago. The FBI reports that the shooter had no connection to an international terrorist group.
It was the deadliest mass shooting in modern U.S. history.

Witnesses say country singer Jason Aldean was playing near the end of the concert when gunfire rang out. Kodiak Yazzi, 36, said the music stopped temporarily and started up again before another round of pops sent the performers ducking for cover and fleeing the stage. The bursts of pops would start and stop for more than five minutes, Yazzi said.
