One automobile, a subcompact Toyota Yaris, was traveling east along the 10 Freeway when it began to speed out-of-control. Unable to stop the vehicle, the driver veered onto the Vineyard Avenue off ramp, where the car collided broadside with a car traveling north on Vineyard.

All four of the occupants of the automobile struck broadside (three men and a woman) were killed and declared dead at the scene.. They have been identified as: 29-year-old Matthew Joseph Pusateri of Mission Viejo; 30-year-old Anthony Andrew Flores of Hemet; 29-year-old Jeffrey Albert Willey of Huntington Beach; and 37-year-old Monica Marie Flores,of Arcadia.

Joel Michael Pineda, age: 7, from Van Nuys, a passenger in the out-of-control vehicle, was transported to San Antonio Regional Hospital, where he was pronounced dead.

Her boyfriend, Andrew Flores (the last name was a coincidence) was also killed.

“Monica was great, she was my older sister. She was fun, she wouldn’t stop. I’d tell her to stop but she wouldn’t she just wanted to play and have fun,” said her brother Carlos Flores.

Toyota has recalled millions of vehicles that have had unintended accelerator issues. But this was something Monica’s family was not yet willing to get into.

“I don’t want to focus on that fight now. I want to lay my sister to rest with respect,” Carlos said.
