As the search for 12-year-old Kayleah Wilson goes on, authorities are sending some mixed messages.

Members of the Union Colony Fire/Rescue Authority scoured the depths of a small pond Monday near U.S. Highway 34 and 35th Avenue behind a Home Depot. But Greeley Police Chief Jerry Garner says Kayleah, who has been missing for nine days, could still be alive. He made a plea to the girl to come home.

“We want you to get back safe,” Garner said (via the Greeley Tribune). “You’re not in trouble. You’re the person we’re trying to help.”

Videotape shows Wilson walking past a mall Sunday afternoon on her way to a birthday party, alone and apparently OK, according to the FBI. Kayleah was last seen by her mother on March 28 as she set off from their home, across the highway from the mall. Before leaving, Kayleah said she would be walking to a birthday party south of the shopping center.

The FBI now says it will offer a $10,000 reward for information regarding the disappearance of the girl (via 9News).
