Michael Jerry Marks, 41, was reported missing in Indianapolis in February 2018. His disappearance ended on March 20, 2018, when investigators found his body buried in a shallow grave beneath a freshly poured concrete slab inside a northwest-side warehouse. Detectives used a concrete saw to exhume the remains after receiving a tip that led them to the industrial building.

Investigators focused on 48-year-old Jason Hancock of Brownsburg, a former employer of Marks. Court documents say Hancock suspected Marks of stealing from the warehouse while Hancock was jailed on a drug charge, and that Hancock lured Marks to the building to discuss restitution. When Marks refused to pay, Hancock allegedly shot and killed him. The documents describe attempts to conceal the death, including removing Marks’s teeth, trips to buy concrete and supplies, failed efforts to dissolve the body with chemicals, and pouring concrete over a pit in the warehouse floor where the body was placed.

Does anyone have information about Michael’s last known movements or about activity at that northwest-side warehouse in early 2018?
