The Sioux City man convicted of seven brutal murders, in 2001, has been found dead in his prison cell.
In a release, a spokesperson for the Iowa Department of Corrections says Adam Matthew Moss was discovered unresponsive in his cell in the Iowa State Penitentiary's Clinical Care Unit shortly before six o'clock Wednesday night.
Moss was found hanging with a bed sheet around the neck tied to a wall vent. Health services staff, and security staff, detached the sheet. But, an examination showed Moss was already dead.
A medical examiner confirmed the cause of death to be asphyxia due to suffocation. Because the death was not due to natural causes, an autopsy will be conducted.
The incident remains under investigation.
Moss was serving a life sentence after admitting to killing Leticia Aguilar, and her five children, Claudia, Zach, Larry, Lisa, and Michael, as they slept back in their west side home in August of 2001. Moss also confessed to killing Ronald Fish at his home on Sioux City's north side.
