A teenager in Arizona has been sentenced to several years in prison for a violent assault on his girlfriend earlier this year, following her refusal to leave her house and speak with him.

On Wednesday, Maricopa County Superior Judge Tracy R. Nadzieja sentenced 16-year-old Troy Aguilar-Olmos to 3 1/2 years in a state correctional facility for the attack, according to officials. This decision came after Aguilar-Olmos entered a guilty plea to two charges of aggravated assault with domestic violence. He received credit for 87 days already served, as confirmed by court records.

Prosecutors from the Maricopa County Attorney’s Office revealed in a press release that in March, Aguilar-Olmos, then 15, threatened to “shoot and kill” the victim unless she came outside to speak with him. When she eventually stepped out, he allegedly “strangled her, threatened her with a gun, and repeatedly punched her.”

Maricopa County Attorney Rachel Mitchell expressed sorrow over the incident in a statement, noting, “The ordeal this young woman went through is deeply disturbing. No relationship, regardless of age, should involve fear or violence.” She continued, “While today’s sentencing cannot erase her trauma, it represents a step toward justice.”

During a brief news conference, Mitchell highlighted the fortune of having the victim’s sister’s boyfriend present during the attack, as he managed to disarm Aguilar-Olmos.

After the incident, authorities quickly located Aguilar-Olmos at his parents’ residence, where he was subsequently arrested.

However, Aguilar-Olmos did not stop terrorizing the victim after his arrest. According to a report from Phoenix CBS affiliate KTVK, Aguilar-Olmos made a series of phone calls in which he continued to threaten her life and the life of her family, apparently out of jealousy.

“I don’t want you to be playing with a guy because if you are talking to a guy and you think that because I’m in jail, I can’t do anything my queen, you are wrong,” he reportedly said in Spanish. “You know I’m going to get out of here and when I get out of here, if I find out about something, watch out.”

He also vowed to burn down a restaurant, again out of jealousy.

“They want to get me f—ing mad if I find out some s— going on in there,” Aguilar-Olmos said on the call. “I’m going to burn the whole restaurant down, and man, they’re f—ing tweaking on me.
