Police and the FBI are searching for a 5-year-old girl in Utah, saying they suspect she may be in danger. The Logan City Police Department said Elizabeth Shelley was last seen at 2 a.m. Saturday and she was reported missing at around 10 a.m.

On Monday morning, police said over 200 officers from a dozen local, state and federal agencies were working on the case. Authorities suspected Elizabeth was in the company of her uncle, 21-year-old Alex Whipple, who was at the family’s home Friday night. The family noticed that Elizabeth and Whipple were gone after waking up after 9 a.m. Saturday, and searched for the pair before contacting police. Police then located Whipple on Saturday afternoon, but without Elizabeth. He has been uncooperative in their investigation of the girl’s whereabouts, after investigators interviewed him for several hours. Whipple was jailed on a probation violation with a $25,000 bond.

During Monday’s press conference, Jill Parker, a victim advocate with the Cache County Attorney’s Office, read a statement from Elizabeth’s family saying they are overwhelmed, scared and saddened by her disappearance.  Elizabeth is 3 1/2 feet tall with curly, shoulder-length brown hair, bangs, brown eyes and was last seen wearing a red tank top and blue jeans.
