Or it may have been a drug deal gone bad. Or she might have been desperate for a fix. Or she might have thought her boyfriend did the shooting. Or she might have been so high she didn’t know what was happening.
I think he would have been upstairs in 5 seconds guns drawn and had them at gunpoint. No way his story holds up.
The autopsy should cover much of this ~ he shot her several times according to his claim. Bet he stuck more in her than bullets.
