The ringleader of a deadly 1977 home invasion has died in prison.
Roger Drollinger and three other men were convicted of killing three teenage brothers and their step-brother in western Indiana.
A Wabash Valley Correctional Facility spokesman says Drollinger was found unresponsive in his cell Wednesday morning and attempts to revive him failed.
The cause of death is not yet clear.
Drollinger was 61 years old.
He was serving four life sentences for the February 14, 1977, shotgun slayings of 22-year-old Gregory Brooks and his stepbrothers, 17-year-old Raymond Spencer, 16-year-old Reeve Spencer and 14-year-old Ralph Spencer.
Their mother and the lone survivor, Betty Jane Spencer, testified against Drollinger and his three accomplices and identified Drollinger as the ringleader.
Spencer died in 2004.
