Illinois State Police (ISP) Division of Criminal Investigation arrested two suspects as part of a death investigation after human remains were found in Lake Mattoon.
Both suspects, 26-year-old James Adams and 62-year-old Robin Turner, are charged with Concealment of a Homicide (Class 3 Felony) and Dismembering a Human Body (Class X Felony).
On the evening of June 28, 2026, boaters observed part of a human arm in Lake Mattoon. The arm had distinct tattoos which were utilized to seek the public’s assistance to aid in the identification. Subsequent searches of the lake revealed additional parts of human remains. After a thorough investigation, ISP Special Agents identified the victim as 38-year-old Dalewayne Turner of Plainfield, IL.
On July 1, 2026, ISP executed a search warrant at Adams and Turner’s residence in the 2400 block of Ruth Fitzgerald Drive in Plainfield. Officers took Adams and Turner into custody. Additional evidence was also recovered.
On July 2, 2026, ISP presented the case to the Will County State’s Attorney’s Office. Adams and Turner remain in custody. The investigation is ongoing and additional charges are expected.
