First look at accused killer David Renz, photo of Clay murder-rape suspect released

David Renz

Officials released the mug shot of David Renz, 29, on Thursday, giving the public its first look at the man accused of killing a Liverpool school librarian and raping a child in Clay last Friday.

The Onondaga County District Attorneyâ??s Office and the New York State Police said in an email that they did not release a photo earlier as it was "critical to preserve the integrity of any identification procedure performed in this case."

Renz is accused of removing an electronic monitoring device before kidnapping Lori Bresnahan, 47, and a 10-year-old girl as they were leaving a gymnastics class at Great Northern Mall. He is accused of binding Bresnahan and raping the girl in a deserted area of the parking lot before driving them to Verplank Road where he allegedly murdered Bresnahan. The girl was able to escape and was found running down the road by a passerby.

Police conducted a massive search on Verplank Road earlier this week, near the location of Renzâ??s arrest. One neighbor told CNYCentral that it appeared police were looking for evidence.

Police have said they believe the attack was random. At a news conference, police said there was no indication that Renz knew the victims.

Renz was facing federal child pornography charges and was on supervised release at the time of the incident. The conditions of Renzâ??s release ordered that he wear an electronic monitoring device, follow a curfew, and not use any monitored computers.

Officials at the New York Northern Probation Department say they believe Renz was able to take apart and reconstruct his monitoring ankle bracket before the attack in Clay. The

transcript from Renzâ??s federal

detention hearing shows that the judge overseeing the case had concerns about allowing Renz to be under pre-trial supervised release.

Federal Judge Andrew Baxter told Renz he would go along with the federal prosecutorâ??s recommendation of supervised release "notwithstanding the very serious nature of the charges that you're facing and what we have learned about your juvenile record." Baxter also noted Renzâ??s "skills with computers" and warned Renz about the consequences of tampering with the monitoring device.

Renzâ??s juvenile record, which Baxter referred to in the hearing transcripts, is sealed in Family Court. East Syracuse Village Court says Renzâ??s case has been waived to a grand jury.

After the news that Renz had been charged with murder and rape, a woman claiming to be a prior victim of Renz reached out to CNY Central. The woman claims Renz sexually abused her when she was about 9-years-old and Renz was about 15. The woman met with the Onondaga County District Attorney's Office on Wednesday and the DAâ??s office confirmed to CNYCentral that they are looking into her claims. We're not releasing the identity of this alleged victim.
