First question I have - since the car keys were found in her jacket pocket...how did someone drive her car back to the church??
This whole case is off. From the Police to the Lexus to the events leading up to JoAnn's demise.
I hate to say this but Follow the Money. Death either brings family together or rips them apart. I think the latter fits this case.
Weeks before this incident, JoAnn mentioned she thinks she is being followed. Why would someone be following her? to get to know her routine. From what I know, doing surveillance can be done by anyone to anyone. Suspected her phone was tapped. Whom or what organization would be capable of this?
I would be looking at all family members, checking and double checking all their alibis and associates of the family members, especially those that were known to have a beef with JoAnn. Phone records might reveal something.
The fact that the Lexus was moved and keys found in her jacket, leads me to believe she was dumped. The Lexus was moved from the Church property. Witness remembers when she left the Church, the driveway was empty of cars. How, if the keys are in JoAnn's jacket? I do not believe JoAnn would walk down a steep embankment in winter with 4inch heels on that were not even scuffed up. Makes me think a second vehicle was involved at least.
The fact that JoAnn carried her purse on the Left side where bruises were found and said to have occurred before death, leads me to conclude that it was an attempt at bringing JoAnn down to the ground or maybe shoved into her car to gain control over her. One person to hold her down and the other person to drive her Lexus. A grown adult woman will fight an attacker if threatened.
If JoAnn was indeed being followed for weeks, this could have been the first time she was alone - to be grabbed.
Also, if those closest to JoAnn knew she never zipped up her coat, why was she found with her coat zipper done all the way up? Someone else did up her coat that did not know her intimately. And as a religious person, suicide is a sin. Even her rosary is missing. Doesn't make sense. Could the rosary be out there?
Are there toll bridges or toll interstates in Detroit or near Grosse Pointe Farms? Cross reference license plates of family or family friends of JoAnn.
Did police check investigate the Lexus for prints, fluids, blood or hair? Backseats, trunk. Did they ever go over it or just release it back to the family? The damaged purse was returned. It is almost as if this was planned and executed very well to look like a suicide but doesn't match to what suicidal people do.
And the whole family drama over the inheritance and aftermath, follow the money.
My thoughts to the family. Justice will prevail.
