A New Mexico sheriff's deputy accused of fatally shooting a fellow deputy following an argument at a hotel has pleaded not guilty.
Tai Chan entered his plea to the murder charge at his first court appearance in Las Cruces on Wednesday.
Police say Chan shot Deputy Jeremy Martin at the Hotel Encanto after the two drank at a nightspot and got into a heated argument. They were staying there after dropping off a prisoner in Arizona.
It's not clear why the two men were arguing.
Records released Wednesday say the girlfriend of Chan heard someone say, "Please don't, please don't," while on the phone with him. The documents say she then heard gunshots.
Chan is being held without bond in the southern New Mexico city of Las Cruces.
