Police say the patrol car was parked in the driveway of the deputy's home on Lake Fenwick Road South when someone opened fire at it from the street as the deputy and his family were sleeping.
No one was hit by the gunfire, and there were no injuries.
A next-door neighbor tells KOMO News he called 911 after hearing four gunshots at about 3:40 a.m. Friday.
Kent police responded to the deputy's home and found bullet holes in the rear of the parked patrol car. Further investigation found that at least one bullet had struck the deputy's home.
Officers closed off the area to search for the drive-by shooter, but there's no word yet on a possible suspect.
