He stumbled into his bedroom to try to retrieve the assault rifle but never got to it, they said.
What an idiot reporter. The perp could not fire his semi-auto (rifle) without being able to retrieve it. A semi-auto is NOT a revolver. Reporter need a little education.

I beg to differ with you. The British built one on a Webley-Fosbery frame. You can see Sean Connery use it in ZARDOZ.
Also, around 1970, some publishers released a Zane Grey novel, NEVADA. The cover art showed a cowboy pulling and firing to his left, two Colt Navy revolvers. You know he was firing fast as the air was full of ejecting cases. ;-D
It was a semi-automatic revolver.
