Cold Justice is back in search of the truth.
Prosecutor Kelly Siegler returns to tackle more gruesome unsolved murders in E! News’ exclusive first look at the Oxygen true crime series’ upcoming eighth season.
“We’re looking into some of the toughest cold cases in the country and time is running out,” Siegler says in the new trailer, released Aug. 22. “We’re digging up new evidence to uncover the truth.”
Working with law enforcement, Siegler and her team—including investigators Steve Spingola, Abbey Abbondandolo, Tonya Rider, Terri Hook, Lesa Hodgkins and Murray Newman—will leave no stone unturned in their hunt to uncover missed clues and track down killers who are still at large.
Their main goal? To finally give the victims’ families and friends peace.
As Siegler adds in the clip, “The worst crime that can happen to you is when someone you love is murdered. And the only way to get through that is to know somebody is trying to do something about it. That’s what we’re here to do. Because if we don’t solve these cases now, they may never be solved.”
And these violent stories certainly aren’t for the faint of heart.
The season eight cases include a recently married Navy veteran that was shot in his home, the mysterious 1999 murder of a Florida grandmother and multiple women who went missing around the country and were never found.
But, as the trailer teases, Siegler’s latest investigations will result in true justice.
The preview shows one male suspect being arrested by police in Kenosha County, Wisconsin earlier this year, per police body cam footage.
An emotional victim’s family member reacts to the news, “I didn’t think that this would ever happen,” while another reflects, “This is a long time coming.”
See everything to come in the trailer above.
Cold Justice returns Saturday, Sept. 13, at 8 p.m. on Oxygen.
Until then, keep reading to look back at some of the most famous true crime cases to ever captivate the world.
JonBenét Ramsey
The 6-year-old pageant star was brutally murdered at her Colorado home on Christmas 1996. Her parents, brother and more have all been suspects, but to this day no one really knows who killed JonBenét.
Nicole Brown Simpson & Ron Goldman
O.J.Simpson, who died in April 2024 after a battle with cancer, was found guilty in a civil trial of both 1994 murders, but in the criminal trial, the jury acquitted him. Technically, in the eyes of the law, the famous NFL player didn’t do it, so their murderer remains unknown (and perhaps at large).
Tupac Shakur
Depending on whom you ask, someone might say Tupac is still alive. But the “Changes” rapper was murdered in 1996, and the investigation is still unsolved.
Notorious B.I.G.
About a year and a half after Tupac, Biggie Smalls was shot four times in a drive-by shooting. His killer still remains unknown.
Caylee Anthony
Casey Anthony, Caylee’s mother, went through a highly publicized trial only to be found not guilty of her daughter’s murder. As a result, it’s still unknown who murdered this little girl.
Elizabeth Short a.k.a. The Black Dahlia
Short, who was murdered in 1947, and the mystery surrounding her death became an instant media sensation. She received “The Black Dahlia” moniker posthumously, but to this day, her killer remains unknown.
Andrew Borden & Abby Borden
This couple was brutally murdered with an axe in 1892, but it was their daughter, Lizzie Borden, who was tried and acquitted for the crime. The deaths of Andrew Borden and Abby Borden were never solved.
Jack the Ripper
In 1888, an unknown serial killer hit the streets of London. More than 100 years later, the identity of Jack the Ripper remains unknown.
The Chicago Tylenol Murders
These murders were a series of poisoning deaths resulting from drug tampering in Chicago in 1982. The victims, who included children, had all taken Tylenol-branded acetaminophen capsules that had been laced with potassium cyanide. A total of seven people died in the original poisonings, with several more deaths in subsequent copycat crimes. The person responsible is still unknown.
The Zodiac Killer
He was a serial killer who acted in Northern California in the late 1960s and early 1970s, but his identity still remains unknown. The killer originated the name “Zodiac” in a series of taunting letters sent to the local Bay Area press. These letters included four cryptograms (or ciphers). Of the four cryptograms sent, only one has been definitively solved.
