"The injuries were significant. It was a very violent attack," police Sgt. Ernesto Gaxiola said in an interview at the scene, praising "the toughness of these victims."
"The fact that the victim was able to communicate to our dispatch, based on the injuries sustained, is unbelievable," the sergeant said. "I can't say enough how incredible it is that they were able to give us information. Hopefully we'll find justice for this."
The suspect being sought in connection with the attack was identified by police as 28-year-old Brian Cruz. He is described as a Hispanic man in his 30s, 5 feet 11 inches tall and weighing 200 pounds.
Cruz was said to be driving a black GMC Denali Sierra pickup truck with a black and yellow California license plate, number BCG1129.
The motive for the crime is under investigation.
