Gardner’s arrest came two days after the department asked for the public’s help in finding Navaeh Allen, a 2-year-old girl who had gone missing earlier in the day from the La Belle Aire area. 

The girl’s mother, Lanaya Cardwell, told FOX 44 that Allen’s stepfather had put her down for a nap around 1 p.m. She said her oldest child came home a few hours later, finding the door open and Nevaeh missing

Multiple agencies helped BRPD in the search for the toddler, including the FBI, Louisiana State Police and the Hancock County Sheriff’s Office. 

The Hancock County coroner told WAFB that the child’s body was found in the Pearlington area of Mississippi, which sits along the border of Louisiana and is about 100 miles east of Baton Rouge. An autopsy is pending to determine the child’s cause of death. 

It wasn’t immediately clear if Gardner has an attorney who can speak on his behalf.
