The actor, 25, allegedly put a handgun to his head "possibly with [the] intent of committing suicide" in a heated domestic fight on Feb. 11, his girlfriend told Phoenix, Ariz., police.
Elycia Turnbow, Muniz's publicist girlfriend, also alleges that the sitcom star "punched her in the back of the head," a police report says.
Muniz's rep denies to TMZ that the actor was suicidal, "A gun played no part in the argument and was voluntarily given to the police for safekeeping," the rep says. "He was not suicidal."
Muniz called police to a Phoenix-area residence Friday around 10 p.m. after a fight over "prior relationships" with Turnbow got out of hand, according to the report.
In his call, Muniz had complained that Turnbow was "throwing things and hitting [him]."
Fight Started in the AfternoonThe couple began fighting earlier in the day at around 2 p.m. with "yelling and screaming" but nothing physical. Muniz told police that at one point during the argument, he accidentally fell and hit his head, and fearing a concussion, he called a friend to take him to the hospital.
After he returned and went to sleep, Turnbow allegedly woke him up by "yelling at him and hitting him in the face about prior relationships" and had demanded his laptop computer. The two tussled, and during Muniz's attempt to get his computer back, Turnbow "fell to the ground and started to kick the bedroom door."
Turnbow told one of the officers that Muniz, prior to going to the hospital, "grabbed a gun and held it to his head" in what she thought was a threat of suicide, according to the report. Turnbow claimed she called one of Muniz's band mates because she "worried about his safety."
After Muniz returned from the hospital, Turnbow claimed he punched her and "threw her into a wall while in the downstairs bedroom."
Muniz denied to an officer that he put a gun to his head, saying he only grabbed the gun case. Asked if he punched Turnbow, he replied, "No. I love her too much. She is the woman I want to marry."
The report added that Turnbow "showed signs and symptoms of drinking alcohol."
Police confiscated Muniz's .380-caliber handgun and because neither showed evidence of physical injury nor was there damage to the residence, both were given a warning and neither was arrested.
