A New York man has been sentenced to life in prison without parole Friday for raping a girl and killing her mother after cutting off his ankle monitor last year.

David Renz learned his fate in Onondaga County Court after a judge said he hoped the penalty would comfort the victims' family.

The 30-year-old had pleaded guilty to first-degree murder, admitting that he carjacked Liverpool librarian Lori Ann Bresnahan and her 10-year-old daughter March 14, 2013.

Divine judgement: Judge Thomas Miller warned Renz that one day he will face 'another judge' who will impose a much harsher sentence

Renz stabbed and strangled the mother as she tried to stop him from raping her daughter.

He had been under federal monitoring on child pornography charges but cut off his ankle GPS.

Renz was sentenced earlier this year to 30 years in federal prison for possessing more than 11,000 images and 1,100 videos of child pornography.



On Friday, Renz remained motionless and wore a blank expression on his face as his sentence was being read.

Judge Thomas Miller had some harsh words for the defendant, whose behavior last March he characterized as 'despicable,' Syracuse.com reported.

‘One day, you will face another judge. One day when you pass from this earth, another judge will impose a harsher sentence for the absolute evil you committed,’ he said.

Some of the slain librarian’s family members read their impact statements from the stand before the sentencing as Renz's relatives sat in the audience.

‘Nothing, absolutely nothing, prepares you for such a tragedy in your own family,’ Bresnahan's cousin Jim O'Hara said.

O'Hara, a former reporter with The Post-Standard, vividly described in his six-page handwritten statement the moment he found out that his relative had been brutally murdered, saying that he felt as cold 'as the most brutal of winter days.'

Kathleen Renz, the convicted killer’s mother, spoke to reporters after her son's sentencing, saying that she prays every day for Lori Bresnahan and her daughter.

Mrs Renz added that she was relieved to learn that federal prosecutors will not seek capital punishment for her son.

'It's a great burden lifted,' the mother said.

The victim’s family pleaded with officials not to hold a death penalty trial to spare Bresnahan’s daughter additional trauma.

The shocking murder of Lori Breshnahan - and the rape of her young daughter - occurred while Renz was awaiting trial for the child pornography charges, and was confined to his home and required to wear a monitoring device.

On March 14, 2013 - just six weeks after he'd been arrested for possessing child pornography - Renz removed his required electronic monitoring device and drove to the Great Northern Mann in Clay, New York, a suburb of Syracuse.

Once at the mall, Renz parked his car and walked around the parking lot, where he found Breshnahan - a school librarian - and her daughter getting into their vehicle.

Renz then forced his way into Breshahan's car using an air pistol he claimed was a real gun and forced her to drive to a remote area of the mall's parking lot where he bound both of his victims and - using a knife to cut a hole in her clothes - raped the young girl.

Prosecutors said Renz was trying to use cable ties to bind the woman to a headrest in her car when she fought back and shouted for the girl to bolt from the vehicle.



As the girl ran off and was rescued by a passing motorist, her mother was strangled and repeatedly stabbed in the head and chest, officials said. Renz was captured by police shortly after.

Weeks after the attack, a report by a federal judge found that the officers failed to do monthly checks on Renz that would have included inspection of the bracelet. Federal probation officers in Syracuse who were monitoring Renz were fired or demoted.

Renz pleaded guilty to the murder and rape charges last year.



Authorities say that several of the child pornography videos found in Renz's possession depicted acts similar to the rape and murder for which Renz pleaded guilty.



'Let the defendant's other victims not be forgotten,' Assistant U.S. Attorney Lisa Fletcher said during Renz's child pornography sentencing hearing in March, according to Syracuse.com.

'Each and every child in each and every one of the defendant's 11,000 images and 1,100 videos for which he stands convicted, every single one of those children was used by David Renz to fuel his twisted interest in the exploitation of children. Every one of them is also his victim.'

Fletcher asked for a sentence of 30 to 70 years, and asked that any sentence the judge imposed would run consecutively with whatever sentence Renz gets for Breshahan's murder.

Renz's attorney, Assistant Federal Public Defender Randi Bianco, asked for a sentence within the sentencing guidelines of 19 to 24 years, citing the difficult life Renz has suffered as the result of a facial deformity .

Renz was born without the lower half of his left jaw and part of his cheekbone - a hereditary condition that would come to dominate his and his family's lives.

The man's father, brother and sister all had the facial deformity but it was more pronoucnded in him, requiring multiple jaw-lengthening surgeries that drained his parents' already limited resources.



In school, his friends recalled that Renz had to cover the hole in his neck from a tracheotomy so he could be heard, drawing bewildered stares from his classmates.
