Major Case Squad suspends investigation of Carlyle woman’s death

The Major Case Squad of Greater St. Louis has suspended its investigation into the death of a 41-year-old Carlyle woman after consulting an expert who analyzes burned human remains.

Sadie L. Tull, who operated a dog-grooming business out of her home on Fairfax Street, was found dead Tuesday after police were asked to conduct a welfare check on her. She was discovered with a single gunshot wound to her head.

Investigators have not determined the manner of Tull’s death, and the decision remains pending the return of laboratory results and search-warrant returns, according to a Major Case Squad news release on Friday.

The leader of this Major Case Squad investigation, Scott Athmer of the Highland Police Department, said detectives received assistance from Elayne Pope, who is experienced in analyzing burned human remains, according to her website.

“At this time, no persons of interest are being sought, and there is no believed threat to the Carlyle community,” the news release states.

Detectives also received assistance from the FBI, the federal Bureau of Alcohol, Tobacco, Firearms and Explosives, the Office of the Illinois State Fire Marshal, Illinois State Police and the O’Fallon Fire Department.

Thirty-six investigators followed up on more than 90 leads in the case.

“The case will remain with the Major Case Squad pending the return of outstanding laboratory results and search warrant returns,” the release said. “Should any new evidence emerge that warrants further investigation, the Major Case Squad will resume active investigative efforts.”
