Police conducted a search on Thursday for a missing Alabama toddler who is presumed dead following his disappearance in September.

WABM reported a heavy police presence at Kahleb Collins’ home in Glen Allen. Collins remains missing weeks after his father and sister were killed in a car wreck in Fayette County on December 8 — when it was revealed Collins was not in the crash.

The children’s mother, Wendy Bailey, 22, was charged on Wednesday in connection with her daughter’s death. Though the children’s father was a driver, authorities determined Bailey was negligent by failing to have her daughter restrained before the crash that killed her daughter and her seriously injured.

In addition to negligent homicide charges, Bailey was charged with child abuse for disregarding and failing to report the abuse Collins suffered at his father’s hands in July. Investigators wrote that, on at least two instances, Bailey witnessed Collins “being bound with rope, physically assaulted, and being bound by a rope from a loft with blood and bruising present.”

Bailey is also charged with abusing a corpse as investigators believe Collins has been dead for several months. Authorities said Collins’ body was put in a bag and stashed in a storage building. His body was eventually discarded at an unknown location, they also said.

Days after the deadly wreck, Collins’ grandfather, John Bailey, 50, was arrested for failing to report Kahleb Collins’ disappearance. He remains jailed on $100,000 bond. Wendy Bailey also remains jailed.
