The homeowner, a 56-year-old man, shot the suspect, a 25-year-old Tacoma man, after the man broke into the home in the 18500 block of Northwest Montreux Drive.
The homeowner was inside the home when he heard somebody ringing the doorbell. He looked outside and, because he did not recognize the man at the door, ignored the doorbell.
A few moments later, the suspect threw an object through a glass front door to enter the home. The homeowner heard a loud crash and saw that the suspect had come inside.
The men struggled, and the homeowner fired two shots from his handgun, striking the suspect once in the shoulder.
A delivery truck driver observed the scuffle, heard the shot and made the initial 911 call about 1:05 p.m.
The suspect was transported to Harborview Medical Center. He has not yet been charged.
The homeowner was treated at the scene for minor injuries.
He was speaking with Issaquah Police while they conduct their investigation.
