On the evening of December 20, 1984, 12-year-old Jonelle Matthews performed in a middle school Christmas choir concert in Greeley, Colorado. Dropped off at her home by a friend’s family, Jonelle vanished without a struggle, leaving her shoes, stockings, and Christmas shawl behind. The case received national attention, with President Ronald Reagan referencing her disappearance in a 1985 speech. For thirty-five years, her fate remained completely unknown until July 2019, when construction crews excavated human remains in a rural oil field—triggering a forensic investigation that convicted 71-year-old former political candidate Steven Pankey.
The Vanishing in Greeley: December 1984
On December 20, 1984, 12-year-old Jonelle Matthews returned home around 8:15 PM following an intra-school choir performance. When her father arrived home an hour later, the garage door was open, the television was on, but Jonelle had vanished. Footprints in the snow outside the window showed someone had peered into the residence before abducting the child.
Despite immediate FBI mobilization and search parties across Northern Colorado, no sign of Jonelle was found. Her case became one of the original inspirations for the National Center for Missing and Exploited Children milk carton campaign.
The 2019 Excavation in Weld County
On July 23, 2019, pipeline construction workers digging in an open field near County Roads 49 and 34 in rural Milliken (roughly 15 miles southeast of Greeley) discovered human skeletal remains. Forensic anthropologists and Weld County Coroners extracted dental records and nuclear DNA, confirming the remains belonged to Jonelle Matthews.
Forensic examination revealed she had been executed with a single gunshot wound to the head shortly after her abduction.
Unmasking Steven Pankey
With the discovery of the remains, Greeley Police cold case investigators focused on Steven Dana Pankey, an eccentric former neighbor who lived just two blocks from the Matthews residence in 1984. For decades, Pankey had exhibited obsessive behavior, filing bizarre court motions claiming intimate knowledge of the crime and demanding immunity in exchange for information.
When police searched Pankey’s electronic devices and questioned his ex-wife, they learned that Pankey had unexpectedly fled Colorado in an RV immediately following Jonelle’s disappearance, claiming a family emergency that never occurred.
Trial, Conviction, and Legal Resolution
In October 2020, Pankey was arrested at his home in Meridian, Idaho. In October 2022, a Weld County jury found Steven Pankey guilty of felony murder, second-degree kidnapping, and false reporting. He was sentenced to life imprisonment, providing definitive resolution to one of Colorado’s oldest and most notorious child abduction cases.
