A man shot and killed his girlfriend’s ex-boyfriend after a second break-in at her house on Friday, Dec. 17, Garden Grove police said.

At around 11 a.m. officers responded to reports of shots fired in the 11900 block of Sycamore Lane in Sycamore Walk, a small, gated community of two-story houses along Garden Grove Boulevard near Harbor Boulevard.

They found a man face down on the staircase with gunshot wounds who died of his injuries. He later was identified by police as Jeffrey Gomes, 46, of Garden Grove, the girlfriend’s ex-boyfriend.

An initial investigation revealed the ex-boyfriend had forced his way into the house for a second time and was heading upstairs when the current boyfriend fired several rounds, according to police.

Five days earlier, they were called to the same location because of an assault with a deadly weapon. The current boyfriend told officers he was in the kitchen with his girlfriend when Gomes broke in through the back door, charged at him with a knife and threatened to kill him, police said in a news release.

The current boyfriend was stabbed multiple times in the chest before escaping to a nearby business for help and later was transported to UCI Medical Center for treatment. Gomes escaped before police arrived.

Gomes had an active domestic violence restraining order against him to prevent him from contacting his ex-girlfriend or going to that location, the release said.

The girlfriend lives at the house. It wasn’t known if the current boyfriend also had been living there, Police Lt. Mario Martinez said.

Police believe there is no threat to the public. The investigation is ongoing and witnesses or anyone with information can contact Detective Lopez at the Garden Grove Police Department, at 714-741-5818.
