The shooter is dead and an “officer-involved shooting occurred during the incident,” according to the Orange County Sheriff’s Department.

The suspect in the shooting was a former law enforcement officer, a law enforcement source familiar with the situation tells CNN.

Authorities are investigating the matter as possibly originating from a domestic dispute between two parties, the source said.

The shooting occurred at Cook’s Corner, a bar and restaurant in the community of Trabuco Canyon, police said.
