UPDATE: Police have booked the uncle on a probation violation and the search continues.

Police officers and volunteers scoured Logan neighborhoods in search of a 5-year-old girl who was reported missing early Saturday morning.

Family members told police they last saw Elizabeth Shelley around 2 a.m. When they woke up at 10 a.m., she was gone. The girl’s 21-year-old uncle had disappeared as well, the family said.

Officers later found that man walking around the northern Utah town around 3 p.m. and detained him, according to a Logan Police Department news release. The Cache County Sheriff’s Office has been questioning him, but said he has not been cooperative.

“We’re very concerned,” said Logan police Capt. Tyson Budge. “At this point, we believe she’s been harmed.”

Elizebeth has shoulder-length curly brown hair and brown eyes. She is 3 feet, 6 inches tall.

Law enforcement is asking for surveillance footage from locations between 300 South and 100 North and 300 West to 600 West to be checked for anything suspicious.

Anyone who sees Elizabeth or has information can call 435-753-7555.
