A woman was killed and another person was injured after being mauled by two dogs at a park in San Bernardino, police said.

Officers responded to reports of a dog attack around 5 p.m. Thursday at Perris Hill Park in the 1100 block of East Highland Avenue, according to Capt. Nelson Carrington of the San Bernardino Police Department.

When officers arrived, they began rendering aid to one of the victims. The officer fired his weapon and killed a pit bull after the two dogs charged at the officer and the victim, police said.

A woman with severe injuries, believed to be caused by the dog mauling, was discovered nearly 30 yards away.

The woman was transported to a hospital where she succumbed to her injuries. The other victim was also hospitalized; their condition is unclear.

Authorities have not released the identities of either person.

San Bernardino Animal Control responded to the incident to help with the animals.
