Dayton Police Chief Richard Biehl released the videos during a news conference Sunday afternoon that showed officers engaging 24-year-old Connor Betts — who was armed with a .223-caliber rifle with magazines capable of holding at least 100 rounds of ammunition — seconds after he opened fire at 1:05 a.m. in Dayton’s bustling Oregon District.

Biehl said police officers on patrol in the area engaged him seconds after the first gunshots were heard and added that Betts was “neutralized” within 30 seconds after the first of “dozens of rounds.” The 24-year-old was shot and killed by police before he entered Ned Peppers Bar.
