Justin Kierman, 31, was shot to death on December 22, 2018, after being found inside a vehicle near the Indian Hills Golf Club in Jurupa Valley. He suffered multiple gunshot wounds, including to the upper back and the back of the head, and died shortly after being taken to Riverside Community Hospital.

Investigators say the killing was premeditated and connected to a domestic situation. Tyler Catlin Borg, 35, of Fontana, allegedly placed a GPS tracker on his wife’s car and reviewed her texts after becoming suspicious that she had reconnected with Kierman. Prosecutors say Borg used his wife’s phone to impersonate her and lure Kierman to a spot near her parents’ home, then ambushed and shot him inside the vehicle.

The trial record presented evidence about planning and the couple’s troubled marriage. The jury found Borg guilty of first-degree murder. Does anyone have information about Kierman’s movements that night or about contacts between him and C.M. leading up to December 22, 2018?
