Rome, NY (WIBX) - Sleeping face down most likely caused the death of an 11-month old child.

Rome Police are continuing their investigation but are now saying that an autopsy is showing that the child died while sleeping on the couch with her two siblings and mom, 30-year old Heather Larson.

Kaitlyn Tennant's legs apparently got trapped between the cushions during the night and she suffocated.

The Oneida County Child Advocacy Center is working with police and the family.
