A multi-agency manhunt to apprehend a male suspect considered "armed and dangerous" continued Sunday in the Silicon Valley area of California. The local police department expanded their search based on their belief that the suspect may have fled the area. Police officers killed the man's accomplice Saturday but have not yet revealed details of the shooting -- including the suspects' alleged crime.

On Saturday, police officers responded to a call alerting them to “suspicious activity” outside of a Motel 6 in Sunnydale, California, according to a press release by the Sunnyvale Department of Public Safety. Sunnyvale is a Silicon Valley town with 140,000 residents and is home to the corporate headquarters of Yahoo Inc.

When the officers approached the vehicle described by the caller, two men fled the scene. The police shot and killed one suspect in the ensuing chase, but the other fled on foot and has not yet been found.

It’s not clear from the department’s press release whether shots were fired by either suspect during the chase. One man did drop a loaded high-capacity magazine, and the suspect who was killed was carrying two guns at the time of his death. Police department spokesman Capt. Shawn Ahearn told NBC News that an 18-year veteran officer fired shots at the suspects Saturday.

Officials say the suspect who is still at large is considered armed and dangerous. Around 70 officers from nearby cities and the California Highway Patrol searched for the missing man for more than six hours Saturday, to no avail. The department tweeted later that night that officials believe he has fled the area.

The at-large suspect, who is a black male in his 20s, was last seen wearing a red or orange shirt and jeans. Anyone with information on his whereabouts should contact the Sunnyvale Department of Public Safety at (408) 730-7110.
