SAN QUENTIN, Calif. — Authorities say a California condemned inmate has died while awaiting execution for two murders.

Corrections officials say 49-year-old Adam Geier was in the recreation yard of San Quentin State Prison when he collapsed Wednesday.

The Department of Corrections and Rehabilitation said Thursday that the cause of death is awaiting an autopsy.

Geier was sentenced to death in 1995 by a San Bernardino County jury in the rape and murder of Military Police Officer Erin Tynan, and the murder for financial gain of Curtis Dean. Dean was stabbed and bludgeoned to death in front of his young children.

Geier was also convicted for the conspiracy to murder Gail LeBouef, who survived being shot in the face.

There have been 14 executions since the state reinstated capital punishment in 1978, while 71 condemned inmates have died from natural causes.
