LA PUENTE (CBSLA) — Four people were injured, two critically, when a car went flying into the side of a home in the San Gabriel Valley.

The crash unfolded late Saturday night at Vineland Avenue and Amar Road in La Puente.

It was there that two cars suspected of traveling at a high rate of speed were involved in a collision. It is unclear if one or both driver’s lost control.

The impact of the crash caused one of the cars to take out two fences (one iron, one concrete) in front of the home, some trees, become airborn.

Footage from the scene showed the car elevate alongside the home. In all, four people were injured. Two were transported to the hospital in critical condition.CBS2/KCAL9 reporter Joy Benedict says the two critical were the drivers of both vehicles.

Two others declined medical treatment.

The family inside the home was uninjured. Jonathan Saldivar and his fiance Monica Paz sleep in the side bedroom of his grandfather’s home.  Thankfully, neither were home when the car came flying through the wall.

“There was a vehicle right next to our window, literally inches from our room,” Saldivar said.

His grandparents were asleep in a room next door.

“It’s terrifying,” says Paz, “because you’re sleeping, you’re in your home. You don’t expect things like this to happen.”

The cause of the crash remained under investigation, though authorities strongly suspect it was due to the street racing.
