SAN ANTONIO, TEXAS – San Antonio police have arrested a woman who they say intervened in a couple’s dispute and shot the man involved in that disagreement.

They found her inside her home at the Rosemont at Highland Park apartments, located in the 1300 block of Rigsby Avenue.

Someone called police to the location around 4 a.m. Monday, saying that a man had been shot.

He was rushed to a hospital in serious but stable condition.

A sergeant at the scene said the woman admitted to pulling the trigger.

He said officers also found a second gun there but it was unclear who owned it. One possibility, he said, is that the victim had brought it there.

Police spent some time questioning other people who were in the apartment at the time of the shooting.

They also searched the parking lot for more than an hour, looking for other evidence.
