Michael Der Vartanian, a 59-year-old commercial airline pilot from Clovis, California, was killed on January 15, 2016 in what investigators described as a botched robbery that turned into an execution-style shooting. He had arrived in his black Mercedes when a group who had planned to rob him lured him into a vulnerable position; the plan involved a young prostitute and several youths, including 16-year-old Zachery Goodwin, who fired the fatal shots.

The attack left Der Vartanian’s family devastated and drew attention because of the violence and the perpetrators’ ages. Law enforcement arrested those believed to be involved and charged them in connection with the killing. Some defendants have acknowledged roles in the plot and the shooting; one admitted to being the gunman and expressed remorse in court.

Can anyone who knew Michael Der Vartanian, his routines, or saw his black Mercedes on January 15, 2016 provide information that might help fill gaps in the timeline?
