Christopher Monroe, 23, was one of four people found dead in an abandoned house on Cleveland’s East Side. The victims — Monroe, Dejuan Willis, 20, Aiyanna Quitman, 19, and Jazmyne Lawson, 18 — were discovered decomposed on mattresses on the floor; medical examiners determined the deaths resulted from multiple gunshot wounds and ruled them homicides. Evidence indicated the killings occurred over a roughly two-week period between September 7 and September 21, 2019.

Investigators say Terrell Silver, 35, entered the home where the victims were staying and shot them. Families were left grieving, including Monroe’s former girlfriend Sierra Hayes and their young son Pierre; Hayes has described the difficulty of explaining the loss to their child. The investigation into the case has continued while the community has offered support to the victims’ families.

Did anyone on Cleveland’s East Side see or hear anything in early to mid-September 2019 that might help fill gaps in the timeline?
