Franklin County detectives executed a search warrant Tuesday at a Villa Ridge mobile home in an investigation into the death of a 5-month-old baby.

Sheriff Gary Toelke said deputies responded to No. 11 Sleepy Hollow Trailer Court, off Highway AT, about 8:25 a.m. to a 911 call and found the baby unresponsive. Officers performed CPR until a Meramec Ambulance crew arrived.

The baby, identified as Michael Kibbons, was taken to Mercy Hospital Washington where he was pronounced dead, Toelke said.

The child’s mother told investigators that she had fallen asleep on a couch and the father was sleeping on a love seat holding the baby in his arms. When the mother woke up she noticed the child was not breathing. The parents called 911 and began performing CPR until deputies arrived.

Toelke said after the ambulance left, a family member locked the door and refused to let deputies back inside the mobile home. Officers then secured the scene and called for the search warrant based on information of possible prior drug activity at the residence.

The sheriff said at this point in the investigation there is nothing to indicate any connection between reports of drug activity and the child’s death.

Detectives are investigating the sequence of events that occurred Monday evening to determine what, if anything, may have contributed to the child’s death, Toelke said. There were no visible signs of trauma to the boy’s body, he noted.
