The murder of Karyn Hearn Slover occurred on September 27, 1996 in Decatur, Illinois, when Karyn Slover, a 23-year-old mother of one, disappeared shortly after leaving her job as an advertising sales representative. Two days later, authorities discovered Slover's dismembered remains, wrapped in plastic bags, in and near Lake Shelbyville.
In 2002, Slover's ex-husband, Michael Slover Jr., his mother Jeannette Slover, and his father Michael Slover Sr. were convicted of Karyn Slover's murder and all three were sentenced to 60 years in prison. The case is notable for being one of the first instances of dog DNA used as evidence in a murder trial.

Disappearance and search
At 5:00 p.m. on September 27, 1996, Karyn Slover left her job in the advertising sales department of the Decatur Herald & Review newspaper, with the intent to pick up her son Kolten and then shop for a dress at the Hickory Point Mall in Forsyth, Illinois. Later that night a black Pontiac Bonneville was discovered in central Illinois on westbound I-72 with its engine still running, its headlights on, and the driver's side door open. The car was registered to David Swann, Slover's boyfriend, but contained some of Slover's personal effects including her purse and driver's license. At this time it was theorized that Slover could have been the victim of a car-jacking, as investigators did not view her as likely to have voluntarily left the area due to her recently signing with a modeling agency for a job.

On October 1, 1996 the remains of an unidentified female body were discovered in Lake Shelbyville, wrapped in plastic bags that were weighed down with concrete blocks. The remains were confirmed to be those of Karyn Slover through her dental records and physical evidence such as a blood droplet and fingerprint were recovered from a bridge that overlooked the lake.

Murder investigation
Slover's autopsy revealed that she had been shot seven times in the head and dismembered using a power saw before being placed into the plastic bags that were sealed using duct tape. Police found several strands of dog hair on the duct tape and remnants of cinders and tall grass. David Swann was an early suspect because of an imperfect alibi. Investigators were also suspicious of several actions that Swann had performed during the initial search for Slover and because he owned a handgun matching the type that had been used to shoot her. Swann participated with police during a search and was eventually cleared of suspicion after footage from an ATM surveillance video cleared him for the missing 40 minutes of his alibi. Alibis for other suspects such as Michael Jr. and Slover's ex-boyfriend also ruled them out as suspects.
A break in the case came in 1998, when police noticed that broken concrete at Miracle Motors, a business owned by Slover's ex-father-in-law Michael Slover Sr., were similar to concrete blocks used to weigh down Karyn Slover's body. A forensic geologist was brought in to see if anything on the Slovers' business matched evidence found at the scene of the crime. The geologist found that not only was the concrete consistent with that found at Miracle Motors, but that evidence found in the abandoned car was also likely from the Slovers' business. The task force sifted through dirt at Miracle Motors and eventually discovered a metal rivet that matched Paris Club jeans and a button that matched to a white shirt, both of which Karyn Slover had been wearing the day of her murder. Police also reported finding bones at the scene, but these were not introduced at trial and were believed to have been animal meat bones that came from food fed to two dogs that Slover Sr. used to secure the property.
