Durborow is being held without bail in the Salt Lake County Jail for aggravated murder and aggravated burglary. The affidavit explains that on October 7, 2020 DNA was collected from Durborow,  submitted to the Utah Bureau of Forensic Services, and the next day a match was made with DNA collected from Sherry’s 2010 crime scene. Also, the affidavit reveals that when Durborow was notified of his Miranda rights he confessed to murdering Sherry. Although at the time of writing this update it is not yet clear how Durborow got on the police’s radar (e.g. initial DNA match, tip from the public), thankfully it looks like Sherry and her loved ones might finally get some semblance of justice.

Case File Overview

On November 30th, 2010, 64-year-old Sherry Black was murdered at B&W Billiards and Books, the bookstore she ran with her husband. The bookshop specialized in rare religious texts and was located at 3466 S. 700 East in South Salt Lake, Utah, right beside Sherry’s home.

Sherry’s daughter, Heidi Miller, failed to reach her mother at the bookstore all morning by phone. Later that afternoon Sherry’s husband, Earl Black, discovered her body in the backroom of the store.

An autopsy later determined that although Sherry had put up quite a fight against her attacker, she had ultimately been brutally beaten and stabbed to death.

Plenty of evidence was found at the crime scene, including the perpetrator’s blood, a partial fingerprint, and a partial palm print. Although it was quickly determined that the blood was from a male, the blood and prints did not match any entries in the FBI’s Combined DNA Index System (CODIS) or fingerprint databases.

An Armani Exchange men’s belt was discovered at the bookstore that did not belong to any of Sherry’s family members. The belt has a waist measurement of approximately 36-38 inches. Additionally,  a sticker was found on the back of the buckle with the number “323”.

Although the authorities have spent countless hours investigating this horrific crime, they have yet to identify a suspect or person of interest: Sherry’s murder remains unsolved.

Case File Theories

Someone from Sherry’s inner circle

Was Sherry killed by someone close to her, like her husband, as is often the case when women are murdered? The level of violence suggests this is a possibility. Veteran South Salt Lake Police detective Joe Sutera explained, “I’ve been doing this for quite a while and this was probably one of the most brutal scenes I’ve seen. She was beaten and stabbed, and it was a violent, brutal scene.” This information gets me wondering if Sherry knew her killer, and if he was compelled by rage and hatred to commit the crime. The brutality of Sherry’s murder and the intimacy of stabbing someone seems to suggest a crime of passion.

Did Sherry’s husband Earl murder his wife and then head off to work to give himself an alibi? Later staging the discovery of Sherry’s body? Although possible, I find this theory highly unlikely. The police never uncovered any evidence that Sherry and Earl had a tumultuous relationship. In fact, detective Sutera is adamant that Sherry’s family was not involved in her murder. He stressed, “We’ve cleared all the family. We’ve looked at them extensively, and you have to in an investigation.” The police appear to have done a thorough job on Sherry’s case so far, so I am going to give them the benefit of the doubt and believe them that the members of Sherry’s inner circle were not involved in her death.

Robbery gone wrong

Was Sherry murdered during a robbery gone wrong? Maybe. Although it is strange that there was no sign of forced entry, none of the rare books appeared to be missing, and the money was even left in the cash register.

Bookseller Ken Sanders, a retailer who owns a store similar to Sherry’s, reported that “rare Mormon books can be worth an extraordinary amount of money.” He explained that “A nice Book of Mormon is a $100,000 book. A rare Book of Commandments is worth a million dollars plus. People will kill for a heck of a lot less than that.” Sherry, though, kept most of her valuable books secured in a safe on site, and Detective Sutera stated that the safe was undisturbed and all of the inventory was accounted for.

Sanders explained to the media that before Sherry’s murder, “a criminal gang of men allegedly stole some extraordinarily rare books, and these books inadvertently were purchased by Sherry Black, and she sold a few of them before it came out that they were stolen and had to be returned.” Lorin Nielsen was one of the sellers of these stolen books, and Sherry helped the authorities prosecute him.

Could Sherry have been murdered out of revenge for her role in dismantling the stolen rare book ring? What at first seemed like an excellent lead, however, quickly fell apart. Detective Sutera said that Neilson was thoroughly investigated, and it was determined that “he’s not the suspect.”

DNA phenotyping reveals a “suspect”

In 2017, seven years after Sherry’s murder, South Salt Lake Police Chief Jack Carruth explained that “advanced DNA information” had helped authorities determine what Sherry’s murderer looked like.

This new DNA technology is called phenotyping; phenotyping is a process used to predict “an organism’s phenotype using only genetic information collected from genotyping or DNA sequencing.” Phenotyping is used to predict “a person’s physical appearance and/or biogeographic ancestry for forensic purposes.” Sherry’s case was the first time phenotyping was used in Utah, but South Salt Lake Police spokesman Gary Keller said, “It’s becoming the industry standard. They use it a lot for found human remains.”

Parabon Nanolabs took the DNA found at the scene of Sherry’s murder and “created images of what the man may have looked like based on genetic code that dictates physical traits, such as face shape, and eye, skin and hair color.” The company determined that the perpetrator is African-American, with light brown to brown skin and black hair. Because the company could not identify the perpetrator’s age from the DNA, Parabon Nanolabs created images of what the murderer would look like at ages 25, 38 and 52.

It is important to note that the DNA evidence used to generate the above images does not “account for weight, hairstyle or other environmental factors.” The authorities stress that the DNA-based reconstructions are scientific approximations at best and will only be used as a guide in the investigation.

Will this new DNA technology help solve Sherry’s murder? I am doubtful, but I guess as long as it is not permitted to narrow the investigation parameters it cannot hurt. I am betting, though, that an “old-fashioned” DNA or fingerprint database hit will be what finally offers some answers in this cold case.

Who do you think murdered Sherry?

It is past time that Sherry’s loved ones get some justice. Sherry’s family has started a website that provides details of the crime and advertises a $250,000 reward for information leading to the arrest and conviction of Sherry’s murderer. They are especially concerned about catching the perpetrator because he could easily strike again. Sherry’s daughter Heidi told the media, “It was a brutal, vicious, horrible crime and I’m scared to death that another family will have to go through what we’ve gone through. Someone who could do this could do it again.”

  1. Mark Noble Mark Noble

    Hi my name is Mark Noble. I dated Heidi Black Miller back in 1984. Her Mom’s murder happened because she refused to take a deal offered to her by the attorney General of Utah. In 1983 a woman named Lecia Salazar was sexually assaulted by a Federal Judge’s son. In return for not pressing charges she wanted one thing. To marry me. So when I started dating Heidi Black Miller they threatened her because they had already planned on making me marry Lecia Salazar. They took the deal they made with Lecia very serious, so when Heidi turned down their offer, they did not take it lightly. In 1989 they killed her brother Jason I assume because they thought he would eventually be a problem for them. Sherry was never the same after her son was killed and kept trying to figure what really happened to him. After 21 years she must have been getting close to figuring out what really happened to Jason so they Killed Sherry. This is only part of my story. In 2016 myself and my 88 year-old mother were evicted from our house in Millcreek. I have spent the two years and eight months figuring why there are 7 mortgages on our house that make absolutely no sense at all. The Attorney General with some help from a detective named Christensen who works for Millcreek PD forced my Mom into giving up control of her checking account in March of 2001. My mom’s checking statements make absolutely no sense at all. The total amount of money missing is $504,500, which they used to kill 13 people between 1988 and 2017. There are also 3,204 checks made out to unknown payees in her checking account. Getting back to Sherry Black I can explain what the 323 sticker on the back of the belt buckle means. it stands for two separate things. The first is the date 3/23/2004. That’s the date they killed one of their own, a cop named Joel Schow. He was assigned to keep an eye on my mom and make sure she stayed quiet about the first three mortgages which were in 1992 and 1993. When they took out the fourth mortgage in February of 2004 they must of felt they couldn’t trust him anymore and in March they killed him. The second part of what 323 stands for is as follows.

    Joel Schow Date of Death 3/23/2004
    Melissa Zollinger Date of Death 12/28/2005 3
    Marshall Higgins Date of Death 12/31/2005

    Kirk Goddard Date of Death 10/24/2010 2
    Sherry Black Date of Death 11/30/2010

    Roger Miller Date of Death 8/18/2013
    Greg Noland Date of Death 3/7/2014 3
    Gregg Goddard Date of Death 5/24/2014

    I have been to the Salt Lake FBI office four times and the Provo FBI office once, but they refuse to help, even though their number one priority is corruption. That’s because they are definitely involved. I would like to sit down and explain this to you in greater detail. I can’t say that you will be able to email without them intercepting it and deleting it because that’s what they did when I emailed Senator Hatch about this travesty of justice. You can sure try to email me though, and I will keep an eye on my inbox. Please, please, please publish something that lets the public know what has really happened. Salt Lake will be a very unsafe place until that happens. THANK YOU Mark
