Nigg said there were four Lakota Hills employees at the pool, although he couldn’t say how many lifeguards were on duty.
A June 14 autopsy revealed the boy drowned and had no medical condition, injuries or marks on his body.
Nigg said last week his death was what pathologists call a “dry lung” drowning, meaning the boy’s airway closed before he aspirated water into his lungs. He said the boy had been under water a short amount of time.
Both the West Chester Police Department and coroner’s office are continuing their investigations.
