A daughter is set to provide evidence against her mother in a homicide case surrounding a woman who was presumed missing until her body was discovered in an Alabama national park.

Jessie Eden Kelly, from Union City, Pennsylvania, confessed to murder on Monday in a DeKalb County, Alabama court, as reported by NBC affiliate WAFF. Initially facing charges of capital murder in Mary Elizabeth Isbell’s death, Kelly accepted a plea for the reduced charge, coinciding with her trial date, leading to a 40-year prison sentence.

She will provide testimony against her mother, Loretta Kay Carr, who remains accused of capital murder in Isbell’s case. Carr’s trial is scheduled for December.

As Law&Crime has previously reported, Isbell was last seen alive in 2021 and reported missing in December of that year by her ex-husband.

Back in 2023, Carr, at 45, and Kelly, then 22, were accused of murdering Isbell. Prosecutors suggested Carr caused Isbell’s death by “pushing her off a cliff” at Little River Canyon National Park, roughly 75 miles from Huntsville, around October 18, 2021, as per Al.com, referencing an investigator’s statement.

It was alleged that this took place “during her abduction or attempted abduction” from her residence, with signs of altercation present, the affidavit reported.

Isbell’s remains were found on June 28, 2023, and were positively identified two days later, on what would have been her 39th birthday.

Her disappearance remained a mystery for years until DeKalb County investigators received credible information in June 2023, leading to Carr and Kelly’s arrests shortly therafter.

DeKalb County Sheriff Nick Wheldon reportedly said that all the women knew each other and appeared to have been connected through someone identified as a “boyfriend.”
