A death row inmate made a chilling confession just hours before he was executed.
David Neal Cox brutally murdered his wife Kim Cox and sexually assaulted his stepdaughter in front of her at their home in Sherman, Texas, in 2010.
He spent more than a decade waiting to be executed, and prior to his death wrote a letter detailing where the body of his missing sister-in-law could be found.
According to district attorney John Weddle, the killer admitted to murdering Felicia Cox, who disappeared in 2007.
He was hand-delivered the note two days after the execution in November 2021.
They claimed Cox felt "deep remorse and wanted to bring closure to her family”.
He was executed on November 17, 2021.
However, shortly before his death, he waived his attorney-client privilege once he was executed, the Daily Star reports.
Cox left a letter with the Mississippi Department of Corrections which allegedly details where the body of his sister-in-law Felicia Cox can be found.
According to district attorney, John Weddle, he admitted to killing Felicia Cox who has not been seen since she vanished in 2007.
His attorneys disclosed the possible location detailed in the letter as Pontotoc County, reports WLBT.
They hand-delivered the letter to Weddle on November 19 and according to them Cox felt "deep remorse and wanted to bring closure to her family.”
A release from the district attorney's office said “Cox provided the alleged location and an admission of guilt” in killing his sister-in-law.
“There was no indication anyone other than Cox is responsible for Felicia Cox’s death,” the release said.
Felecia’s daughter, Amber Miskelly hopes she can finally give her mother the burial she deserves.
“At this point, I’m just wanting to find my mother,” she said. “I hope we do find her remains with the information David left... I just want to be able to give her a proper burial. What she deserves.”
Since the letter, Weddle's office has been working together with the sheriff and investigators to hunt for the mother's remains.
They have called upon archaeology and anthropology experts from Mississippi State University to assist with the search.
“We would like to stress that locating the remains of Felicia Cox is not a foregone conclusion,” Weddle said.
Detectives hope the recovery efforts are accurate so they can help the family carry out their final wishes.
