A man is accused of killing his wife late Monday after an argument ended in a shooting at an Uptown Dallas hotel, police said.

At 10:16 p.m., a 911 caller reported that a woman in a room at Hotel ZaZa in the 2300 block of Leonard Street was screaming and possibly high on drugs, police said.

While Dallas Fire-Rescue was on its way to the hotel, the caller told the dispatcher that the woman was threatening suicide. The ambulance arrived at 10:25 p.m., and emergency responders stood by, awaiting officers' arrival per department policy.

About an hour later, at 11:26 p.m., patrol officers were assigned to the call. Three minutes later, a gunshot was heard at the hotel.

Police arrived at 11:32 p.m. and found a 32-year-old woman dead in the hotel room.

Her 30-year-old husband was found nearby and was hospitalized for a separate medical issue, police said. Investigators believe he shot his wife after an argument.

Authorities have not released the names of the couple.
