It was supposed to be a regular July Sunday in Topeka. Family members were gathering for a fish fry, the kind of mid-summer ritual that defines life in the Midwest. But when Mike Sisco and Karen Harkness didn’t show up, and calls went unanswered, the celebration turned into a search. What they found in the basement of Karen’s home on July 7, 2002, wasn't just a crime scene—it was the beginning of a twenty-three-year legal odyssey that would tear families apart and lead to one of the most controversial serial prosecutions in Kansas history.
Mike Sisco and Karen Harkness were found in bed. They had been shot multiple times—five for Karen, and between five and seven for Mike. The weapon was a 9mm.
Here is the thing that immediately baffled investigators: nothing was missing. Karen was still wearing her Rolex and a diamond bracelet. Mike’s wallet, stuffed with nearly a thousand dollars in cash, was right there in his shorts. This wasn't a robbery gone wrong. It was, as Sergeant Richard Volle later described it, an "emotional execution."

The Long Road to the Dana Chandler Conviction
For nearly a decade, the case sat cold. Everyone had a hunch, sure. The families of the victims pointed fingers almost immediately at Mike’s ex-wife, Dana Chandler. They described a woman who couldn't let go, who allegedly stalked Mike, even jumping on a trampoline in his backyard in the middle of the night. But hunches don't hold up in court, and for years, prosecutors said they simply didn't have the physical evidence to charge her.
That changed in 2011. A new District Attorney took over and decided the circumstantial evidence was enough.
The first trial in 2012 resulted in a conviction, but it was far from the end. In 2018, the Kansas Supreme Court overturned that verdict. Why? Because the lead prosecutor, Jacqie Spradling, was found to have made up evidence. She told the jury about a nonexistent protection order and suggested Chandler had been seen at a gas station near the crime scene—something that was never proven. Spradling was later disbarred for these "intolerable acts of deception."
A Legal Marathon in Pottawatomie County
If you think one trial is exhausting, imagine three. After the 2012 conviction was tossed, a second trial in 2022 ended with a hung jury. Seven people wanted to convict; five weren't convinced.
It wasn't until June 2025 that a final resolution arrived. Because the case was so well-known in Topeka, the third trial was moved to Pottawatomie County. After years of GPS monitoring and legal limbo, Dana Chandler was once again found guilty. In June 2025, Judge Cheryl Rios sentenced her to two consecutive life terms. She won't be eligible for parole for 50 years. By then, she would be well over 100 years old.

What Really Happened with Mike Sisco and Karen Harkness?
The prosecution's case was always built on a "jealousy and obsession" narrative. They argued that Mike Sisco and Karen Harkness were finally happy, and that was the one thing Dana Chandler couldn't stand. Mike and Karen had been dating for four years. They had just spent the night before their deaths at a casino, laughing and enjoying each other’s company.
The defense, led by Tom Bath, never wavered. Their argument was simple: there is zero physical evidence. No DNA. No fingerprints. No hair. No murder weapon was ever found. They argued that the police suffered from "tunnel vision," focusing so hard on the ex-wife that they ignored other possibilities, like a random burglary involving two local men who were later caught forging a check from one of Mike’s accounts.
Why This Case Still Matters in 2026
Honestly, the Mike Sisco and Karen Harkness case is a case study in the power and the pitfalls of circumstantial evidence. You’ve got a defendant who maintains her innocence to this day, claiming she was in Denver at the time of the murders. You’ve got children, Hailey Seel and Dustin Sisco, who had to testify against their own mother.
Hailey’s victim impact statement in 2025 was gut-wrenching. She called her mother an "evil killer" and talked about how she had lived in a "fairy tale" for years before accepting the reality of what happened. It’s a level of family trauma that most people can't even fathom.
The Facts vs. The Narrative
- The Timeframe: The murders happened between 2:00 AM and 3:00 AM on July 7, 2002.
- The Weapon: A 9mm handgun. It has never been recovered.
- The Alibi: Chandler claimed to be driving through the mountains in Colorado, but her gas receipts and mileage didn't quite line up with her story.
- The Misconduct: The disbarment of the original prosecutor remains one of the biggest stains on the Kansas legal system.
The "justice" here is complicated. For the families of Mike Sisco and Karen Harkness, the 2025 sentencing brought a close to the legal battle, but the 23-year delay left deep scars. It’s a reminder that the legal system is human, messy, and sometimes incredibly slow.
If you are looking for a clear-cut "smoking gun" case, this isn't it. It's a case of patterns. It’s about the cumulative weight of strange phone calls, inconsistent stories, and a motive that spanned a decade.

For those following cold cases or true crime, the takeaway is clear:
- Preserve the record: The misconduct in the first trial nearly let a double-murderer walk free.
- Look beyond the obvious: While the jury eventually sided with the prosecution, the lack of physical evidence remains a talking point for legal experts.
- Support for victims: The children of the victims and the accused are often the ones left to carry the heaviest burden for the longest time.
