A Michigan family mourns after a weekend accident at a friend’s dairy killed their 4-year-old son.

According The Alpena (Mich.) News, officials found Connor Michael Kasubowski in a septic tank at an Alcona County, Mich., dairy. Despite efforts to save the child, he was pronounced dead at a local hospital.

Alcona County Sheriff Doug Atchinson says that he will put together a special Child Death Review board to investigate the accident.

"It is their responsibility to look into the circumstances of the death of a child and see if there is anything to potentially prevent this type of accident from happening in the future," Atchison said. "Our investigation is indicating there doesn't appear to be any wrong-doing.”

The tragedy is similar to the 2010 death of a 5-year-old Alpena, Mich., boy who was also killed in a septic tank accident.
