The Greenbrier County Sheriff held apress conferenceThursday to share details of the incident after an investigation was concluded.

Oreanna Myers, 25, was the biological mother of Kian Myers, 4; Aarikyle Nova Myers, 3; and Haiken Jirachi Myers, 1. She was step-mom to Shaun Dawson Bumgarner, 7 and Riley James Bumgarner, 6, and married to Brian Bumgarner.

Oreanna shot the kids after picking up Shaun and Kian from the school bus that afternoon, Sloan said. About an hour after she had picked the boys up, a neighbor called in a 911 call to report that the house was on fire.
