The parents of four sisters found locked in the back of a truck have been charged with child endangerment.

Mississippi Highway Patrol spokesman Cpl. Johnny Poulos said the girls, ages 7, 10, 11 and 15, were discovered in the back of a rental truck.

John and Kimberly Leinweber of Atlantic Beach, Fla., were charged with four counts each of child endangerment, according to Poulos. Authorities said the family was traveling to Louisiana.

The couple is being held without bond in the Hancock County jail pending an initial court appearance, Poulos said.

The sisters were released into the custody of a grandparent from Louisiana.

Hancock County deputies found the children Monday, according to Poulos.
