LINCOLN, Neb. -- Authorities reported on Monday that an inmate from Tecumseh State Correctional Institution (TSCI) died Sunday. 

The Nebraska Department of Correctional Services (NDCS) said that 70-year-old Necdet Canbaz died Sunday, Nov. 27. 

NDCS said that Canbaz was serving a life sentence on charges out of Douglas County that included first-degree murder and use of a firearm to commit a felony.

As is the case whenever an inmate dies in the custody of the NDCS, a grand jury will conduct an investigation.
