I saw an account that the GSR was inconclusive.
Not sure about the # of rounds.
A newer account had him meeting with a biker gang member to arrange for a *hit* on the lady who was uncovering his embezzlements.
Police officer is investigating loss of funds from community program. Arranges to meet with someone to get info. Is jumped, dragged off into weeds by a group, shedding gear on the way. Is shot once with own pistol, (hit body armor), shot again (mortal wound), perps discard pistol and leave officer for dead.
Son cries foul and story grows to discredit whole family, son, wife, etc.
Someone investigating this is the one who siphoned off the money and the deceased officer is the fall guy.
This doesn't make any worse a teevee plot than what they are saying.
The trail leads back to dirty cops, in the above scenario, but not necessarily the deceased.--oh, and blame bikers, right?
