The murder of Nancy Marie Bennallack remains one of the longest unsolved cold cases in history. For nearly 52 years, the Sacramento Police Department has been trying to solve the brutal stabbing murder of the 28-year-old court reporter. Not only is this one of the longest unsolved cold cases in the US, but it also remains one of the biggest unsolved mysteries in the world.
This brings up the question: what is the longest cold case ever solved? It’s a difficult question to answer as many cold cases go unsolved for decades. But, despite the odds, some cold cases have been solved after many years of investigation. For example, a cold case from the 1970s in England was recently solved after 41 years.
But then there are those cases that remain unsolved for even longer than 41 years. What is the longest cold case ever solved? Are there any cases that have been solved after more than 50 years? Where are the cold cases with the most unsolved homicides? Who has solved the most homicides?
These are all questions that demand answers if we are to truly understand the complexity of unsolved cold cases. In this blog post, we will take a look at the longest cold cases that have been solved, the unsolved cold cases with the most homicides, and the detectives who have successfully solved the most homicides. So, if you are curious to learn more, keep reading to find out what is the longest cold case ever solved!
What is the longest cold case ever solved?
When a crime is unsolved for many years, it’s referred to as a cold case. While cold cases can be solved in a matter of days or weeks, some remain unsolved for decades. In fact, the longest cold case ever solved took close to 52 years to crack.
The murder of Nancy Marie Bennallack, a 28-year-old court reporter who was brutally stabbed to death in October 1970 in her Sacramento apartment, remained a cold case for nearly 52 years. Initially, the case was classified as “unsolvable” due to the lack of evidence and witnesses. However, in 2021, the case was finally solved thanks to a breakthrough in DNA technology.
The Cold Case: What We Know
Nancy Marie Bennallack’s murder was especially gruesome. She was found stabbed to death in her bedroom, with multiple stab wounds on her body. The crime scene was also disorganized, indicating that the killer had ransacked her apartment in search of something.
At the time of the murder, there were no witnesses, and the police were unable to gather any evidence from the crime scene. The case went cold for years, with no suspects or leads.
The Breakthrough in DNA Technology
In 2021, a breakthrough in DNA technology helped solve the case. The police decided to re-examine the evidence from the crime scene, and this time, they were able to identify a full DNA profile of the killer.
This breakthrough came thanks to a new DNA technology called “Next Generation Sequencing”. This technique is able to analyze a person’s entire genome, and it can even work with degraded samples that would have previously been impossible to analyze.
Using this technology, the police were able to match the killer’s DNA to a man named David Wynn, who was already in prison for an unrelated crime. Wynn was arrested and charged with murder.
The arrest of David Wynn in 2021 marked the end of the longest cold case ever solved. While Wynn has yet to be convicted of the crime, the breakthrough in DNA technology used in this case gives hope to other unsolved cases.
Thanks to the advancement of DNA technology, more and more cold cases are being solved every year. As forensic science continues to improve, we may see even more cold cases solved in the near future.
So, while the murder of Nancy Marie Bennallack may be the longest cold case ever solved, it certainly won’t be the last. Thanks to the advancement of DNA technology, more and more cold cases are being solved every year. It’s only a matter of time before we hear more stories of cold cases being solved.

Law enforcement agencies in the United States are doing their best to solve unsolved homicides. Many police departments have formed special task forces or “cold case” squads dedicated to solving these long-term cases. Additionally, new technology is helping to solve cases that had previously remained unsolved for years.
For example, the use of DNA evidence has helped to solve many cases. This evidence can be used to link suspects to the crime scene, or to link multiple cases together. Additionally, law enforcement agencies are increasingly using social media and other forms of digital media to find new leads in unsolved cases.
What Can We Do to Help?
The best way for citizens to help with unsolved homicides is to report any suspicious activity to the police. If you have any information about an unsolved homicide, you should report it to the police immediately. Additionally, you can help spread awareness of unsolved homicides by talking to friends and family about it, or by joining a local organization that is working to solve cold cases.

What state has the most cold case murders?
When it comes to unsolved homicides and cold cases, California has the most of any state in the United States. This is according to the Murder Accountability Project, which compiles data from the FBI’s Uniform Crime Report. While no one state has the highest rate of cold case murders, the sheer number of unsolved homicides in California makes it the state with the most.
The Murder Accountability Project
The Murder Accountability Project (MAP) is a non-profit organization that was founded in 2015. The organization works to bring together data from a vast number of sources, including the FBI’s Uniform Crime Report, to compile a comprehensive picture of unsolved homicides and cold cases in the United States.
The MAP has identified a total of 208,366 homicides in the United States since 1960, and of these, there are currently 49,741 unsolved homicides and cold cases. This means that there are over 23% of homicides that remain unsolved. In addition, the data shows that there are disparities in the number of unsolved homicides and cold cases in different states.
California has the most unsolved homicides and cold cases
California has the most unsolved homicides and cold cases of any state in the country, with 8,028 unsolved cases. This is followed by Texas, which has 4,552 unsolved cases, and Florida, which has 4,089 unsolved cases.
The high number of cold cases in California can be partially attributed to the state’s size, as it is the most populous state in the country. However, this is not the only factor. According to retired FBI Special Agent in Charge Stephen Backmann, there is also a “violent component” in cities that have a large population.
The challenge in solving cold cases
Solving cold cases can be a challenge, as they often involve complex evidence and witness testimony. In addition, many cold cases involve homicides that occurred decades ago, and it can be difficult to identify suspects after so much time has passed.
To help with this, many states have established cold case units, which are specialized units within law enforcement that are dedicated to solving unsolved homicides and cold cases. These units work to follow up on leads, review evidence, and interview witnesses in order to identify suspects.
The importance of solving cold cases
Solving cold cases is important for a variety of reasons, including providing closure to victims’ families and increasing public safety. When a suspect in a cold case is identified, they can be prosecuted and held accountable for their actions. This can help prevent them from committing further crimes.
In addition, solving cold cases can help increase public safety by allowing law enforcement to identify patterns and trends in criminal behavior. This can help them develop strategies to prevent future crimes and identify suspects in other cases.
