Iowa Department of Corrections officials say 61-year-old Charles Lasage died on Sunday of a chronic illness.
Lasage was sentenced to life in prison after being found guilty in the sexual assault and murder of Rosalyn Barnes of Des Moines, who’s body was found in a ditch near Adventureland in Altoona in October 1991.
The case led to Lasage also being found guilty of raping and killing another 11-year-old girl in New York in 1986.
