He said that his gun accidentally fired once then several more times when he tried to gain control of the weapon.
Some additional information:
An officer in a patrol car down the street from the residence heard the shots and responded to the scene to find McNeil and his friend fleeing in separate vehicles, according to the College Station Police Department.
The officer managed to stop McNeil's friend and gave dispatchers a description of McNeil's vehicle. He was arrested a short time later.
If Mr. Ronald Wayne McNeil is stupid enough to believe this firearm “accidentally” fired 15 shots at Ms. Lacie LaRose, he's deranged. A firearm doesn't go off by itself 15 times unless it is intentional. Where death results, it's called First or Second Degree Murder, depending on premeditation or spur of the moment action of the shooter. Either way, McNeil will not have to worry about where he will be staying for the rest of his life.
