Death in the family

My brothers wife has a son named Baker from a previous marriage. Wednesday night he left in his tesla to go pick up a client at the air port. When he did not come back home and never answered his phone Bakers wife got on the computer and tracked down his Teslas location. She found him dead of a gunshot. It apprears the so called client he was picking up was a hit man. He was in the car 20 mins according to the onboard computer. His mom my brothers wife of course is devistated as well as his own wife.
No idea what Baker was doing that would get him killed. Funeral is Friday. Police are investagating.
