Police in Florida say they were forced to kill a man when responding to a gruesome crime scene on Sunday.

An officer shot and killed a man holding a knife-along with a piece of his roommate. 

It happened around 11:30 p.m. on Sunday. The Fort Myers Police Department responded to a report of a woman and two small children hiding in a carport.

Officers spoke to the woman, who said her husband, Willy Lumaine, was actively killing their roommate.

Upon arriving at the home, they noticed the front door was open with a trail of blood leading inside.

The officers immediately secured the perimeter around the home and began issuing verbal commands in an effort to locate the husband and any possible victims.

The man, later identified as the female's husband, Lumaine, approached a rear window and began to smash it out with a massive knife.

As officers continued to yell at Lumaine to drop the weapon, he climbed out of the window, holding the knife in one hand and what seemingly looked like a dismembered body part in the other.

He refused the commands and exited the window, heading toward the officers, so the fired their duty weapons, striking Lumaine and incapacitating him, according to police. 

He was later pronounced dead.

Police found evidence of a violent attack inside the residence and discovered the roommate's mutilated and dismembered body inside and outside of the home, according to the Fort Myers Police Department.

The involved officers have been placed on paid administrative leave per department policy as the Florida Department of Law Enforcement conducts an officer-involved shooting investigation simultaneously with the police department's investigation.
