Chan and fellow deputy Jeremy Martin were spending the night at the Hotel Encanto in Las Cruces after transporting a prisoner to Arizona.

Witness testimony revealed the men had been drinking and arguing in the hours before the killing inside the hotel.

Chan’s first trial ended in a mistrial when the jury failed to reach a verdict. Chan claims he shot and killed Martin in self-defense. The prosecution told jurors Chan shot Martin in the back five times.

Friday, Chan testified in his own defense, telling jurors he and Martin argued over a double homicide in Santa Fe.

Chan, who acknowledged both he and Martin were intoxicated, said Martin was acting strange and aggresive inside the hotel room.

“He had this stare. I will never forget how he was looking at me when he pointed the gun at me. It just happened so fast,” Chan said, “Then I remember just being hit on the face and blanking out and falling on the floor.”

“I knew he had the gun and I just remember saying, ‘I have to grab the gun.’ I reached out for the gun and a shot went out – I remember a loud bang and a ringing in my ears,” Chan recalled.

“I have the gun, I have the gun,” Chan recalled saying, “I could not believe I had the gun and then I got up and started shooting.”

“What were you thinking,” the defense attorney asked. “You just can’t explain it. He was trying to kill me,” Chan answered.

Chan said the grabbed the gun and forced it out of Martin’s hand. He remembers Martin running out into the hallway. “I can stop shooting now,” Chan recalled saying.

Chan testified he ran into the hallway and started yelling “sheriff’s office” and “I need help.”
