A fight among family members at a Miami-Dade home led to a man pulling out a gun, and after negotiating with that barricaded man for about six hours, police shot him dead.

Officers responded to a home on Northwest 171st Street, near Northwest Miami Court, just after 2 p.m. Tuesday. Sometime during the family dispute, one man took out a gun, Miami-Dade police said.

Family members were evacuated, and the armed man barricaded himself inside.

A SWAT team responded and attempted to negotiate with the man for about six hours.

Finally, at around 8 p.m. they entered the home.

Police said there was an exchange of gunfire between offices and the man, who was wounded and rushed to Aventura Hospital and Medical Center, where he died.

“The special response team and the hostage negotiators pleaded with the subject for several hours to remove himself from the residence, but he refused to do so, at which point, the special response team entered the residence,” Det. Khristopher Welch of the Miami-Dade Police Department said. “There was a confrontation, an exchange of gunfire.”

It’s unclear what the family argument was about, how many people were inside the home and how many officers opened fire.

The Florida Department of Law Enforcement is investigating the officers’ decision to use deadly force.
