(KLZA)-- A Tecumseh State Correctional Institute inmate died Tuesday at a Lincoln hospital. 

According to a release from the Department of Correctional Services, staff members were alerted to the cell of 22-year-old Daelan Lamere on May 27, where he was unresponsive and having difficulty breathing.  Lamere was taken to the Johnson County Hospital in Tecumseh, and later transferred to the Lincoln hospital where he remained until his death. 

Lamere was serving a 6 to 11 year sentence from Douglas County for four counts of robbery and one count of use of a deadly weapon to commit a felony. 

The Nebraska State Patrol will investigate Lamere’s death.  The official cause of death has not been determined.  Reports indicate Lamere tested positive for methamphetamine and ecstasy at the hospital.

Whenever an inmate dies in the custody of the Nebraska Department of Correctional Services, a grand jury will be convened to conduct an investigation.
