WESTCHESTER, Fla. (WFLA) — A landlord is behind bars after he reportedly shot a tenant dead after an argument over the thermostat turned physical, according to NBC affiliate WTVJ.

On Saturday, Miami-Dade deputies responded to a home in the 9400 block of Southwest 17th Terrace in Westchester, to find a man with a gunshot wound.

According to the report, 37-year-old Adam Louis Anson, armed with a semi-automatic pistol, tried to get into the victim’s home by knocking on a window because he wanted to adjust the thermostat in the hallway.

When the victim opened the door, Anson forced himself in and began punching him. He then dragged him to the backyard and shot him multiple times in the head, WTVJ said.

After Anson shot the victim, he reportedly went back inside, adjusted the temperature, and went home to call 911. According to the report, Anson claimed he shot the man in self-defense because he was attacked.

The victim, identified as 57-year-old Carlos Alberto Gonzalez, was taken to a nearby hospital where he later died from his injuries.

One resident told WTVJ they heard three gunshots and that they were so loud, that he felt like the gunfire was in his own home.

“After seconds, I was able to recognize that something wrong was happening in my backyard and I was extremely scared,” the resident said. “I started screaming and I called my husband, ‘Hey go to the backyard because I feel a stranger is in the backyard.’ Then I heard boom, boom, boom, boom.”

Anson was arrested on charges of second-degree murder with a weapon, according to court records.
