On the morning of July 7, 2002, police were alerted to a grim discovery in Topeka, Kansas: Mike Sisco (age 47) and his fiancée, Karen Harkness (age 53), both shot dead while asleep in their home. Despite more than $1,000 in cash, a Rolex, and jewelry still present, investigators quickly ruled out robbery or burglary. What emerged instead was a crime driven by rage and obsession.

The Suspected Motive: Obsession and Stalking
Mike and Karen were in a loving relationship—they even celebrated Fourth of July together just days before. But Mike’s ex-wife, Dana Chandler, became a person of keen interest. Following their 1998 divorce, she reportedly stalked Mike—showing up at his home late, making hundreds of calls—and he had obtained a protection-from-abuse order against her.
Neighbors testified that Chandler made bizarre appearances, even jumping on her ex’s trampoline undetected. From afar, Mike recorded instances of her disruptive behavior in his planner .
Investigative Hurdles: No Physical Evidence
Investigators had no DNA, fingerprints, or murder weapon. The bullets came from an Israeli manufacturer, but that didn’t tie back to Chandler. Phone data showed Chandler’s calls stopped for 27 hours—raising speculation she was intentionally avoiding phone tracking .
However, a gas station clerk placed her car in Kansan territory on the night of the murders—a point of contention due to lack of receipts or clear documentation.
Trial One (2012): Conviction Overturned
In 2011, Chandler was arrested and charged. Her first trial (2012) ended in conviction based largely on non forensic evidence: obsessive phone records, stalking patterns, and her own incriminating verbal admissions caught on tape. However, that conviction was overturned in 2018 because of prosecutorial misconduct—chief deputy DA Jacqie Spradling had misled the jury with false claims (including an alleged restraining order), resulting in her disbarment.
Trial Two (2022): Hung Jury
A second trial began in July 2022, with Chandler maintaining that she was in Colorado at the time. Again, no new physical evidence emerged—prosecutors relied on her obsessive behavior. After a tense six day deliberation, the jury was deadlocked (7 for, 5 against conviction), and no verdict could be reached.
Trial Three (Feb–May 2025): Final Verdict
The third trial moved to rural Pottawatomie County in early February 2025. Chandler represented herself, persistently denying guilt, citing lack of evidence, and accusing courts of bias.
Her daughter, Hailey Seel, emotionally testified. She recounted chilling examples of Chandler’s jealousy—late-night harassing calls, visits to surveillance spots, and demeaning remarks directed at Karen.
After the prosecution emphasized Chandler’s obsessive control and the emotional execution, the jury—after about four hours of deliberation—returned guilty verdicts on both counts.
Sentencing: Life Without Parole
On June 3, 2025, Judge Cheryl Rios sentenced Chandler (65) to two consecutive life terms, with no chance of parole for 50 years—also crediting her 13 years already served.
- Hailey Seel’s victim impact statement was especially moving: “Boy, was I fooled. I believed that she loved me. She stole my dad…My heart was torn out and stomped.”
Chandler continued proclaiming innocence, alleging the proceedings were a “circus,” and vowed to fight on appeal. Critically, DA Mike Kagay affirmed their belief in Chandler’s guilt and their duty to the victims.
