Officers with the Sacramento (CA) Police Department responded early on Thursday morning to a call of an armed, masked man walking on a city sidewalk.

Officers found a suspect matching that description at of the subject, and the man ran away as officers tried to make contact. The suspect—who has not yet been identified—fled into a residential area and officers established a perimeter.

SWAT Officers were called, and they later found the subject in a back yard. Upon making contact, officers opened fire, fatally shooting the subject.

"He posed an immediate threat to officers, and two SWAT officers fired on the suspect," police spokesman Vance Chandler told the Sacramento Bee.
