HARRISBURG, Pa. -- The mother of an 8-year-old Pennsylvania boy whose decomposing body was found on the third floor of their house says she didn't know he had died until noticing the smell.

Kimberly Tutko tells Pennlive.com that her husband was the primary caretaker of their mentally disabled son. She says Jarrod Tutko waited several days to tell her the boy had died.

Police charged Jarrod Tutko on Saturday with child endangerment, concealing the death of a child and abuse of a corpse. Court records do not list an attorney for him.

Harrisburg police say Tutko informed his wife about the boy's death "when the odour of decomposition became too strong."

It's not clear how the boy died. An autopsy is scheduled.

The couple's five other children have been placed in protective custody.
