A man shot and killed one of three burglars who broke into his East Side Tacoma house Monday afternoon, police said.

The man was home alone about 2:15 p.m. when he heard somebody at the door of his two-story house in the 3800 block of East J Street, police said.

After seeing a trio of men sneak around to the back sliding door and hearing glass break, the homeowner went upstairs and locked himself in a bedroom.

At least one burglar made his way upstairs and was about to enter the bedroom when “”the resident opened fire through the door, striking the suspect several times,”” police spokesmanMark Fulghum said.

The burglar who was shot was pronounced dead at the scene. His identity has not been released.

Officers who responded to the scene used a police dog team to track a second suspect, who was arrested shortly after the shooting. A third suspect was still on the loose.

The alleged burglars are between the ages of 19 and 22.

Fulghum said he’s unsure why the men broke into the home in broad daylight or whether the owner of the home might have known them.

The homeowner, who was not hurt in the incident, was not arrested.

Police were searching the house and the suspects’ vehicle after securing warrants Monday night.
