EDWARDSVILLE, Ill. (AP) — Two brothers from St. Louis have been charged in the death of an acquaintance whose body was found in Glen Carbon, Illinois.

First-degree murder charges were filed against 29-year-old Ralph Evans and 31-year-old Julius Evans in the death of 45-year-old Tyrone Grady, also of St. Louis.

Madison County Sheriff John Lakin on Tuesday refused to detail the shooting or a possible motive, but said an overdose death on Feb. 8 of a St. Louis woman is connected.

Authorities did not specify the relationship between the woman, the Evans brothers and Grady, other than saying the four have been acquainted for years.

Authorities say the men have been in custody since Feb. 14 and were formally charged on Feb. 16. The warrants for the arrests were sealed until Tuesday. The brothers are being held in lieu of $2 million bail.
