LAKEPORT, Calif. – Police are on the lookout for a Lakeport woman who allegedly took part in a home invasion robbery late last week.

Raiven Monica Shepherd, 30, is wanted in connection to the robbery, which happened last Friday, Aug. 30, according to Lt. Jason Ferguson of the Lakeport Police Department.

Ferguson said Shepherd is considered armed and dangerous, and is wanted for first degree robbery, terrorist threats and assault with a deadly weapon.

As part of the investigation, officers requested a be on the look out for Shepherd, Ferguson said.

Ferguson said police already have taken into custody another suspect in the case, 47-year-old Tod Dean Syper of Nice.

Just after 10 p.m. last Friday Lakeport Police officers responded to a reported physical altercation in the 500 block of First Street between five subjects involving bats and a firearm, Ferguson said.

When officers arrived they contacted the neighbor, identified as Jerry Musick, who reported hearing someone yelling for help next door at Ben Perry’s residence, according to Ferguson.

Musick reportedly went next door and found Shepherd and Syper standing near a bathroom holding baseball bats, Ferguson said. Inside the bathroom was Ray Bell who was at the residence to visit Ben Perry and Lori Ridgel.

Ferguson said that at some point Bell exited the bathroom and a verbal altercation broke out. Shepherd and Syper fled to the backyard where they were followed by Musick.

While in the backyard Shepherd allegedly pulled out a small caliber handgun and pointed it at Musick, who reportedly yelled, “She has a gun.” Ferguson said Musick's son tossed him a 12-gauge shotgun and Musick fired two rounds at a travel trailer in an attempt to dissuade Shepherd and Syper, who both fled the area.

During the investigation officers learned that both Shepherd and Syper arrived at Perry’s residence and demanded money, keys and cellular phone from Ray Bell by using threats, Ferguson said.

At some point Shepherd and Syper became aggressive and Shepherd brandished the gun and threatened to kill Ray Bell before he fled to the bathroom and locked the door, according to Ferguson.

Approximately two hours later, officers located Syper at N. Starr and Armstrong streets and placed him under arrest for first degree robbery, false imprisonment and assault with a deadly weapon. Ferguson said officers searched the area for Raiven Shepherd but didn't find her.

Syper was transported to the Hill Road Jail, where his bail was set at $285,000, Ferguson said.

Jail records indicated Syper remained in custody on Thursday, with a court appearance set for next Tuesday, Sept. 10.

Raiven Monica Shepherd is described as an adult American Indian female, 5 feet 4 inches tall, 135 pounds, black hair and brown eyes.

The investigation is ongoing and anyone with information is asked to contact the Lakeport Police Department at 707-263-5491.
