A Maine man who held two people hostage while in Maine State Prison has died in a New Jersey prison.

Michael Chasse was found unresponsive in his cell today. He was serving a 12-year sentence for robbery, aggravated assault and a number of other crimes. He also had been convicted of two counts of kidnapping for the June 30, 2008, hostage standoff in which he used a homemade knife to hold another prisoner and the prison librarian hostage. He was sentenced in December to 40 years for that conviction.

Chasse, originally from Lewiston, was transferred to the New Jersey State Prison Jan. 3 shortly after his sentencing because of the hostage situation in Maine.

A statement from the Maine Department of Corrections gave no indication of the cause of death. The department statement said New Jersey authorities will conduct any investigation into the death.
