Michael Dennis was 13 when he disappeared from Hammond, Indiana. He and a 16-year-old friend, James Raganyi, were last seen on September 10, 2002, near the apartment of 49-year-old David Maust. The boys had reportedly visited Maust’s second-floor apartment during the summer and were given money, beer, and marijuana.

Investigators later found the bodies of Michael, James Raganyi, and a third victim, 19-year-old Nick James, entombed in concrete in the basement of Maust’s apartment building. The remains were wrapped in heavy plastic and duct tape and had to be excavated with a jackhammer. Michael and James Raganyi’s suspected cause of death was strangulation or suffocation; Nick James died from blunt force trauma to the head.

David Maust, who had been released from prison in 1999 after a prior murder conviction, had been arrested on October 2, 2002, on a charge of contributing to the delinquency of a minor for allegedly providing Michael and another boy with marijuana and beer. After the bodies were discovered he was taken into custody and charged with the three murders.

Does anyone have information about Michael’s last known movements or contacts around September 10, 2002?
