5-year-old child killed in dog attack

A 5-year-old child was killed in a dog attack at a home in Oro Grande, an unincorporated community in the Mojave Desert of San Bernardino County, Monday afternoon, authorities say.

Deputies responded to the 15100 block of Portland Street just before 3 p.m. and located an unresponsive child suffering from significant injuries, the San Bernardino County Sheriff's Department said.

The child was in the back portion of the house with a family dog at the time of the attack, according to authorities. It appears the dog involved may have been a pit bull, according to reports from the scene, but authorities have yet to officially identify the type of dog that was involved in the attack.

It was not immediately clear what happened to the dog once law enforcement arrived on scene.

No further details were immediately known. The investigation is ongoing.
