Sheila Mills spent her final hours bound and bleeding after her ex-boyfriend forced his way into her St. Louis County home and executed her with a gunshot wound to the right temple—one day after she ended their tumultuous relationship via text message, according to court records.
Background
Darryl Greenlee, 61, and Sheila Mills, 64, had been in a relationship that investigators described as "of a turbulent nature." On August 2025, Mills sent Greenlee a text message ending their romantic involvement. The following morning, around 6:30 a.m., Greenlee arrived at her Northwoods residence and began knocking on her window and calling for her attention to get her to open the door, according to a criminal complaint filed by St. Louis County police.
When Mills answered the front door, Greenlee forced his way inside her home. Local police later found Mills dead with her hands bound behind her back and a fatal gunshot wound to her right temple after her daughter requested a welfare check.
"At no time are any other individuals seen entering or exiting victim's residence," investigators noted in the complaint, establishing that Mills did not invite anyone else into her home that morning.
The Charges
Greenlee was tried and found guilty last week of first-degree murder and armed criminal action for Mills' killing. A second man, Kevin Shelton, is scheduled to stand trial beginning Sept. 28 on charges including murder, armed criminal action, robbery and other crimes connected to Mills' death.
Prosecutors alleged that Shelton served as Greenlee's accomplice in the break-in and slaying. Investigators said Shelton was seen leaving Mills' residence wearing a mask and gloves. He is accused of stealing Mills' vehicle and using her debit card to withdraw $140 following the killing.
Police recovered a trash bag that Greenlee discarded into a nearby garbage bin after departing Mills' home with Shelton. The bag contained a tequila bottle bearing Greenlee's DNA, according to court records.
Greenlee is scheduled to be sentenced on Oct. 23 in St. Louis County Circuit Court.
