The FBI is offering a $10,000 reward for information in connection to the discovery of the body of a 6-year-old girl in suburban Fort Worth, Texas.

Police in Saginaw, Texas, a town of about 20,000 northwest of the Dallas-Fort Worth area, found the body of Alanna Gallagher under a tarp this past Monday night near her family's home, KTVT reports.

Authorities say that they've received leads about a truck that was seen in the area where Gallagher's body was found. They don't suspect any of her family members to be suspects.

"We urge anyone with information about her to contact the police," Allana's father, Karl, said.
