Jessica Lynn Roggenkamp, 44, of Anderson, California, went missing in early December 2016 after planning to visit a friend in Igo. She was last seen the morning of December 9, 2016, with a sleeping bag and pillow packed for the trip. Two days later her black 2010 Ford Mustang was found unlocked and abandoned on a remote stretch of Highway 36 with the gas tank empty; her keys, sleeping bag, pillow, a duffel bag, and clothing remained inside.

Investigators say Roggenkamp changed a flat tire at that location on the morning of December 10 with help from two transit employees who reported she was alone and said she was headed to a party in the Harrison Gulch area near White Rock Road. She was reportedly going through a difficult divorce at the time. Roggenkamp is described as a white female, 5 feet 6 inches, about 195 pounds, with brown hair and brown eyes, and tattoos including a rose on her left breast, daisies on her left leg, and an infinity symbol on her right wrist. The Anderson Police Department is handling the case and a Secret Witness of Shasta County reward has been offered for information.

If anyone knew Jessica’s plans that week, her movements on Highway 36, or the party at Harrison Gulch, can you share what you know?
