A 26-year-old man was fatally shot by a law enforcement officer early Monday morning in Maryland, officials said, after an earlier domestic situation involving a woman.

The incident unfolded around 1:30 a.m. on Sandy Spring Lane in Thurmont, Md., about 60 miles north of Washington.

Officials with the Frederick County Sheriff’s Office said Abraham Arellano of Thurmont, Md., broke into the home through a back window. Earlier that day the local police department had helped a woman who lived at the home file a protective order against Arellano, who had recently moved out because of “ongoing domestic issues.”

Authorities said there was concern that a woman and her children were inside the home.

When officers from the sheriff’s office arrived they found Arellano coming from the backyard of the home and walking down the driveway and then back to the home. He said he had a gun and was told several times to put down the gun, but he refused, officials said.

A deputy then “discharged his patrol rifle one time” and struck Arellano, officials said. He was pronounced dead at the scene. Deputies searched the home and found no one was there.

The incident is under investigation. The sheriff’s deputy is on administrative leave, which is standard policy for the department.
