Summary based on the NamUs case record (MP10760) and 13 other sources
Dawn Marlene Allen, aged 50, disappeared from her home in Carroll, Iowa, on May 4, 2011. She was last seen around 8:30 p.m. that night, but she never showed up for work the next morning at a local Subway, where she had worked for over 20 years. Her white Chevrolet Blazer was found abandoned in the parking lot of a local bar, The Piranha Club, early the next day. The vehicle was not at the location when the bar closed the night before, raising suspicions about the timeline of her disappearance.

Dawn was dating a 54-year-old married man, James Snovelle, who had falsely claimed to be separated from his wife. Snovelle became a person of interest after investigators linked him to her disappearance. When authorities approached him in Kansas five days after she went missing, Snovelle fled and ultimately took his own life before police could question him. Although there was no direct evidence connecting him to Dawn’s disappearance, police believe he may have been involved.

Despite extensive searches and ongoing efforts, Dawn’s whereabouts remain unknown, and foul play is suspected. Investigators continue to seek information that could lead to resolving her case.
