Chance Walsh, the 9-week-old toddler who went missing back in September, was allegedly beaten to death by his own father, court documents have revealed.

The documents state that Chance died in the early hours on Sept. 16 after Joseph Walsh repeatedly struck his infant son to death multiple times. The body of the baby was left to decompose in the bedroom before being buried in a shallow grave near the couple's home in North Port, Fla.

An unredacted report states that Joseph killed Chance by suffocating him with a baby wipe as his wife Kristen Bury looked on. "You are going to break his (expletive) neck," Bury told her husband, based on police reports released Tuesday, News-Press.com reported.

Sally Sucino, the baby's maternal grandmother, first told authorities that she hasn't seen her grandson for about a month. She added that the baby's parents allegedly told relatives inconsistent stories about their baby's nonattendance.

They told relatives that "the child was unharmed, that he died in [a car] crash and that they gave him to a woman at a hotel in Georgia," police said, according to People

The parents are currently held in the Sarasota County Jail and are set to face charges of first-degree murder and child neglect.
