An investigation is underway into a shooting involving a Los Angeles County sheriff’s deputy who investigators say was stabbed during an altercation with two suspects in the East Los Angeles area Friday morning.

The shooting was reported shortly before 4 a.m. at the Speedway Express gas station bordering East Los Angeles and Commerce in the 5700 block of Whittier Boulevard.

Authorities at the scene said deputies initially responded to reports of a someone using a gas pump while lighting objects on fire at the station.

They arrived to find an adult male standing behind an SUV near the gas station’s market, Lt. Derrick Alfred said.

The man was ordered to walk to the deputy and complied, but then turned and attacked the deputy when he got close, Alfred said.

The fight went to the ground and as the deputy was on his back a woman came out of the SUV with a sharp object, possibly a knife.

The woman then reached over the man and stabbed the deputy in the face, Alfred said.

“At that point, the deputy was able to retrieve his firearm. He fired two to three rounds. He struck both the male and the female,” Alfred said.

The man was taken to a local hospital in critical condition.

The woman died at the scene after being shot in the head. A 10-inch folding knife was found under her body, authorities said.

Neither of the suspects have been identified.

The deputy was treated at a local hospital and has been released, Alfred said.

It was unclear exactly what objects were being set on fire and why the suspects chose to do it at the gas station.
