Redding

An Anderson woman whose car was found abandoned this weekend is missing, but police do not consider her disappearance suspicious.

Jessica Roggenkamp, 44, was last seen at 3 a.m. Saturday, according to Nor-Cal Alliance for the Missing. Her 2010 black Ford Mustang was found off a remote stretch of Highway 36 after she apparently changed a flat tire but she wasn't there.

She'd been heading for a friend's home in Igo. Police said she brought a sleeping bag and pillow but never made it to her destination.

A Department of Fish and Wildlife warden on Sunday night spotted the Mustang unlocked with the keys inside but no sign of Roggenkamp, or a struggle, police said.

She'd also not made any phone calls since Saturday, according to data from her cell phone, Anderson police said.

Anderson police Sgt. Casey Day said his department is not considering Roggenkamp's disappearance as suspicious.

"At this point, we don't have any set of suspicious circumstances," Day said. It appears she voluntarily left, he said.

He said Roggenkamp's disappearance had no similarities to Redding mother Sherri Papini's abduction in November.

Papini went missing after going for a jog near her home northeast of Redding on Nov. 2. Three weeks later she was found beaten and chained near Interstate 5 in Yolo County after her captors released her on Thanksgiving day.

Shasta County sheriff's officials are still looking for her captors.

Roggenkamp has brown hair and brown eyes, is about 5 feet 6 inches tall and weighs 122 pounds. She takes prescription medication, according to the group.

Police said Roggenkamp is familiar with the area where police found her car and had visited the same area on Thanksgiving Day. Anderson police are coordinating with Trinity County search and rescue teams to look for her, they said.

Officers still believe Roggenkamp disappearance is voluntary and said there are no indications of foul play, they said.
