Phoenix police Officer Shane Figueroa

Phoenix police Officer Shane Figueroa was killed, according to investigators, at the hands of a illegal immigrant drunk driver.

The collision happened at 19th Avenue and Roeser Road. Figueroa, a 25-year-old police officer with a wife and young daughter, was responding to a shooting call at 1:30 a.m. Saturday when his squad car was T-boned by a white truck in the intersection.

Edward Campos, Jr. found himself in the middle of a car wreck scene doing everything he could to save a dying officer. "I told him help is on its way…just to hang in there and everything is going to be all right."

Nevertheless everything would not be all right and Figueroa would not survive the crash.

Police say his squad car was hit by a white truck. There were two people inside that truck, Salvador Vivas-Diaz, aka Jose Vivas Gonzalez and Jose Salvador Vivas Gonzalez, and a passenger.

Detectives say Vivas-Diaz was not only drunk driving but he is an illegal immigrant with four warrants out on him under another name and two of those warrants are for driving while under the influence.

Edward says when he got to the crash scene, which happened right outside his house, he found Figueroa lying on the hood of his smoking squad car.

As a trained first responder, Campos did everything he could but it was all for not. As a father himself, he says his heart goes out to Figueroa's family who lost him while in the line of duty.

Investigators will continue to look into this crash and are now waiting on the lab results on Vivas-Diaz's possible alcohol use.

Vivas-Diaz is facing several charges, including manslaughter, aggravated assault and possibly DUI.
