The suspect, Shane Albatross Stanscheit, 25, of Hemet, was traveling northbound on Cornell Street when he blew through the stop sign and collided with a car going westbound on Stetson Avenue at approximately 1:30 a.m.
Upon impact, the suspect vehicle flipped over and landed on the shoulder of Stetson Avenue.
The vehicle that was struck was pushed farther forward and plowed through a yard of a nearby home, stopping just a few feet away from the residence.
That vehicle was carrying a family of five. The father, who was driving the car, was killed and the mother and the three children were hospitalized with serious injuries, said the California Highway Patrol.
"I came out and there was a truck practically in my house," described the Diana Becerra, who was in the home that was nearly struck by the hit vehicle.
The passenger in the suspect car was ejected from the vehicle and later died.
Becerra was still in her house when she heard the suspect yelling out that passenger's name. When he didn't get a response, he took off running north on Cornell.
The suspect later showed up at the house of his friend who was killed. That's when officers arrested him.
Many area residents said they've seen plenty of car crashes at the intersection of Cornell and Stetson and want a four-way stop implemented.
