Summary based on the NamUs case record (MP3913) and 6 other sources

Mary Alice Helm, aged 44, was last seen on January 16, 2007, in the Alta area of Placer County, California. She had been staying at a friend's house when she apparently went for a walk and never returned. At the time of her disappearance, Helm did not take essential items such as her purse, extra clothing, or the medication she required to manage her diabetes, raising concerns about her well-being.

She was last seen in the vicinity of Kearsage Mill Court near the Drum Forebay exit of Interstate 80, east of Colfax. Helm’s friends reported her missing when they couldn't locate her after returning home. Although there are no immediate signs of foul play, authorities believe she could be in danger due to her medical condition and the unusual circumstances of her disappearance. Despite search efforts, no trace of Helm has been found, and her case remains unsolved.
