A Florida man has been charged in the death of his girlfriend after he survived a botched murder-suicide pact at a shooting range and fled to New York, authorities said.

Alec Almanzar, 23, and Ayadalis Chalas, 21, had agreed to die together and went to the Hot Shot Shooting Range in Holly Hill, Florida, on Oct. 7, the Daytona Beach News-Journal reported.

They rented a 9mm Glock at the business, police Lt. Chris Yates told the news outlet.

“Basically, they just put their heads together and he shot into her head. The bullet went through her head into his head” Yates said last week, adding that it was unclear why they decided to die.

A suicide note has not been found.

According to surveillance footage, the couple talked to a staff member about gun safety before they requested two targets and obtained eye and ear protection and a box of ammo.

A camera recorded Almanzar talking to Chalas as he loaded the gun and then fired at the targets.

He then positioned himself so the right side of his head was touching the left side of Chalas’ head, the paper reported.

He pointed the weapon and pulled the trigger, but it misfired. After checking the gun, he fired three shots at the target before shooting at Chalas’ head as his head touched hers, police said.

When first responders arrived, Chalas was dead and Almanzar was sitting in a chair with a compress to his head.

After being released from the hospital, Almanzar went with his family to New York — but was extradited to Florida to face second-degree murder charges, Yates said.

“They knew that the charges were coming down,” he told the paper. “Now he is back in our custody and will be facing the charges.”
