Twenty-five-year-old Jason Roy Wilson of Chino Hills died at the scene Friday morning.
Authorities say he stabbed a roommate at around 5:30 a.m., attempted several carjackings and finally stole a woman's minivan at gunpoint before leading deputies on a four-mile chase.
Authorities say Wilson crashed in a Chino Hills field, ran through neighborhood yards, broke into a family's home on Brushwood Court and confronted the husband before leaving.
Deputies say they confronted Wilson nearby and shot him when he charged at them with a knife and gun.
The stabbing victim was listed in stable condition.
