Two men began knocking on the front door of a North Memphis, Tenn. home on Tuesday. When a woman answered, the men barged in, and one of them — identified as 22-year-old Nico Carlisle — held a gun to the woman's neck.

A male homeowner also inside the house heard the commotion, retrieved his own handgun, and fired several shots at the two men, hitting and killing Carlisle.

Carlisle's accomplice left the scene and has not been found. Police said Carlisle had an extensive rap sheet that includes charges for burglary and assault. Police also cleared the homeowner of wrong-doing.

At least one neighbor appeared to defend Carlisle.
