An Alabama mother has been arrested after allegedly notifying investigators that her missing one-year-old toddler had died, and his body was kept in a storage shed, according to a criminal complaint.

The discovery was made shortly after Wendy Pamela Bailey, 22, was involved in an accident that claimed the lives of Steven Bradley Collins, 40, and Ryleigh Collins, 2. 

A third child, Kahleb Rowan Collins, 1, was unaccounted for.

They also believe that Bailey knew the body had been put in the storage shed.

In the complaint, photos allegedly show some of the abuse through images of the child bloodied and hanging from a rope and of him lying on the floor covered in bruises.

Officials also say that he sent messages saying, “He want move” and “I’m so sorry” and finally “He moving.” and that Bailey replied, “He just looks wore out and tired and hopefully that’s all.”

“His body has not been recovered, although law enforcement teams are still actively gathering information and searching for his remains,” officials said.
