Man in prison for role in child porn ring beaten to death, officials say

MILAN, Mich. (AP) - Authorities say a man serving a 40-year sentence for his role in a child pornography ring has died following a fight involving seven inmates at a federal detention center in southeastern Michigan.

A statement Friday from the Federal Bureau of Prisons says Christian Maire had life-threatening injuries following the "altercation" Tuesday at the Milan detention center about 50 miles southwest of Detroit and was pronounced dead.

Details of how he was injured weren't immediately released, but the death was being investigated as an apparent homicide. The prison was placed on "limited operational status" with visiting suspended.

The statement says three of the other inmates involved were treated for serious injuries and two prison staff members had minor injuries.

The detention center is adjacent to the low-security Milan prison .
