LAKE COUNTY, Calif. — The Lake County Sheriff’s Office is seeking public assistance in locating a Middletown woman missing since the fall.
Anne Marie Jamieson, 58 — also known as Anne Marie Mancini — was reported missing on Nov. 29, the sheriff’s office said.
A Tuesday press release said detectives have been investigating the case, collaborating with Jamieson’s family and surrounding law enforcement agencies.
Jamieson is described as 6 feet, 2 inches tall, approximately 200 pounds, with blonde hair and hazel eyes.
Authorities said she is known to frequent the Middletown, Cobb and Calistoga areas.
Detectives determined that she was last heard from in May or June of 2024. However, “We can’t say whether or not that’s when she went missing,” said Sheriff’s Public Information Officer Lauren Berlinn.
The case was reported to authorities in late November, about six months after Jamieson’s last known contact, Berlinn said.
Jamieson’s case was posted on the Lake County Sheriff’s Office Facebook page on Monday and a press release was issued the following day — which created a 45-day delay in seeking public assistance.
“We were doing the investigation, we were trying to get the pieces together of whether or not she was actually missing since the last known contact was June,” Berlinn explained.
Berlinn said the length of that gap varies in such cases. “It really depends on the situation and the person and their lifestyle and the information that we’ve able to gather immediately or if we need the community’s assistance.”
Jamieson has been added to the California Department of Justice’s Missing Persons Database.
Lake County now has a total of 12 active cases of missing persons in that database, with the oldest case stretching back to 1980.
If anyone was in contact with Jamieson during mid to late 2024 or has any information regarding her whereabouts, please contact the Lake County Sheriff’s Office Major Crimes Unit Tip Line at 707-262-4088.
