HOWARD TOWNSHIP, Mich. (AP) - Authorities say an 11-year-old boy has died after being found at the bottom of a pool during a birthday party in southwestern Michigan. The Cass County sheriff's office says the boy was in the pool with several other children Saturday night at a home in Howard Township when he didn't resurface. He was spotted at the bottom and the sheriff's office says children pulled him to the surface before parents started CPR. The boy was taken to a hospital, where he was pronounced dead. The department didn't immediately release his name. The death is being investigated as accidental.
