They say David Renz can now be sentenced to life in prison without parole based on his guilty plea in Onondaga County Court.
Renz is scheduled to be sentenced on Friday.
Accused of a host of felonies – including rape, kidnapping, and murder – David Renz pleaded guilty in July 2013 to murder in the first degree and predatory sexual assault in the first degree.
His plea agreement included the promise that he could withdraw the guilty plea if prosecutors pursued the death penalty.
Renz’s sentencing was delayed while Federal prosecutors deliberated pursuing the death penalty in connection with a potential Federal carjacking charge and the resulting murder of Lori Bresnahan.
The death penalty can’t be pursued by Federal prosecutors without the Attorney General’s authorization.
Renz has already been sentenced on separate Federal charges for child pornography.
He was sentenced to 30 years in prison in the child pornography case.
In March 2013, Renz, who was already facing Federal child pornography charges, used an air pistol to force Bresnahan, a Liverpool Central School District librarian, into her car, along with the child, as they were leaving a gymnastics center at the Great Northern Mall in Clay.
Once they were in a secluded parking lot, Renz sexually assaulted the child.
After he drove to Verplank Road, Renz tried to tie Bresnahan’s head to a seat, but she screamed, telling the child to run away.
Renz stabbed Bresnahan repeatedly at the Verplank Road location. She died from her injuries.
State Police found Renz hiding in a wooded area.
They found the child’s blood on him, along with the keys to Bresnahan’s vehicle.
Authorities discovered that Renz had neutralized a monitoring bracelet he was wearing as part of his pre-trial agreement with a Federal judge in the child pornography case.
