The report says that the officer was hosting a party, dancing with his wife, when the woman, Adaisha Miller, hugged him from behind and the weapon fired.
According to the report, the officer didn't know the woman, who was 24 years old.
There's something unexplained here.
Report says the piece was a .40 S&W M&P. Like the Glock, the M&P is striker-fired, and in theory, can't go off unless the trigger is pulled. Supposedly worn in a waistband holster under a shirt. Doesn't say what the carry position was, strong-side, weak-side, muzzle down or cross-draw.
There is some controversy about the possibility of an accidental discharge with Glocks in holsters, some back and forth on the net about whether this happens or not. Haven't seen this with the S&W. Supposedly you can drop the M&P all day long and never get an AD.
If the only way for this weapon to fire is by pulling the trigger, then somehow she must have gotten a finger inside the guard. but the only way I can see a hip-holstered duty weapon killing somebody behind you with a heart-shot is a ricochet. Or if it was cross-draw and the the woman was squatting, or on her knees hugging him around the waist.
Be interesting to hear what the investigation finds.
