A Clifton woman and her three children are now considered endangered missing individuals in a Mesa County Sheriff's Office investigation.
Shiann Moore, 27, Lillie Faries, 10, Timothy Pearce, 7 and Sabrina Pearce, 10 months, were last seen Saturday night at a home on East Carolina Avenue in Fruita.
Moore's family reported her missing on Monday, according to the Mesa County Sheriff's Office. Moore could be traveling in a 2001 silver Pontiac Grand Prix with Colorado license plate GOA169.
The investigation so far indicates that Moore left with her children of her own accord, said spokeswoman Megan Terlecky.
"The fact that (Moore) hasn't been heard from for several days is concerning and we would like to get ahold of them to make sure they are safe," Terlecky said.
The endangered missing person alert, issued through the Colorado Bureau of Investigation, is a statewide notification and will be posted to highway alert boards.
Moore is a white female, 4-feet, 11-inches, 125 pounds with blonde hair and blue eyes, though she could have a different hair color. Lillie is 4 feet tall, 60 pounds with blonde hair and blue eyes.
