Woman arrested after man found dead… lying on top of her

To quote from a report by a local police department in Michigan, earlier this month:

Livingston County Dispatch received a call about a possible death at a residence located in the Woodland Ridge Community on Shady Brook Ct, South Lyon, MI. Officers from the Green Oak Township Police Department arrived on scene finding a woman in her bed with an obviously deceased male on top of her. After the initial investigation it was determined this was a homicide. It was determined the victim was struck several times with blunt force in the head and stabbed several times in the chest and neck. The female suspect was transported to UofM Hospital for evaluation while in custody. Once released a short time later, she was lodged in the Livingston County Jail. The suspect and the victim have been in a long-term relationship and living at the residence with their son who was unharmed in the incident.

So what made the woman a suspect?  While the police don’t appear to have released any details, questions and speculation prevail on social media.

So, either someone killed him while he was on top of her or she killed him and put him on top of her like a blanket.

I was thinking she was stabbing and hitting him while he was on top of her, then he died and fell onto her getting her stuck. Like maybe he was hurting her and she was defending herself?

Was his name Gerald? Did she have handcuffs on?

Who the heck call the police?  The poor kid?
