Lakeport police are asking for the public's help in locating a woman suspected in an armed home-invasion robbery last week.

Raiven Monica Shepherd, 30, of Lakeport, was one of two people who came to a residence in the 500 block of First Street on Aug. 30 armed with baseball bats. They demanded money, keys, and a cellphone from occupants, police said in a release.

When the three people at the residence resisted, the incident escalated to an armed confrontation in the backyard, with Shepherd brandishing a handgun and the would-be victim of the robbery, identified as Jerry Musick, discharging a shotgun to scare off the intruders, police said.

Shepherd and her companion, Tod Syper, 47, of Nice, then fled. Syper was arrested a few hours later and charged with first degree robbery, false imprisonment, and assault with a deadly weapon, but officers could not locate Shepherd, who is wanted on charges of first degree robbery, terrorist threats and assault with a deadly weapon.

Shepherd is described as a Native American, 5 feet, 4 inches tall, 135 lbs., black hair and brown eyes. She is considered armed and dangerous, police said.

Anyone with knowledge of her whereabouts may contact Lakeport police at 263-5491.
