The Walton County Sheriff's Office said deputies responded to a Santa Rosa Beach home on a call from a woman who reported her husband had been attacked by a stranger.
The couple told investigators a man was pounding on their door around 11:10 p.m. Monday and the husband answered the door to find a stranger who forced his way into the residence.
The man started choking the husband and the pair struggled until the victim was able to get free, deputies said.
"You are the wrong man," the suspect allegedly told the husband before fleeing the home.
The victim gave deputies a description of the man and the vehicle he was using. Deputies located the suspect and identified him as David Lord, 42.
Lord told deputies he believed his girlfriend to be cheating on him and he wanted to confront the man he had seen her with earlier in the day. He said he went to the wrong house, knocked on the door, apologized and left.
Lord was charged with burglary of an occupied dwelling and simple battery. He was booked into the Walton County Jail.
