Bio 

Douglas Donald Moore was born in 1968 and lived in Ontario, Canada. He was known in the Meadowvale area of Mississauga and was later described in reports as a drug supplier to young teens. Before the murder investigation, Moore was already known to the criminal justice system as a convicted pedophile. In 2004, Ontario legislative discussion described him as a convicted pedophile and a prime suspect in the death of 15-year-old Rene Charlebois. Reports also stated that he was awaiting trial on sexual assault charges involving young boys when he died in custody.

Moore’s name became connected to the disappearances and deaths of Robert Grewal, Joseph Manchisi, and Rene Charlebois after the victims disappeared in late 2003 and their remains were found in 2004. Since Moore died before any murder trial could take place, the available record is based on police allegations, court proceedings involving people accused of helping him after the fact, and later reporting.

Murder Story

In late 2003, three young men from the Mississauga area disappeared, Robert Grewal, 22, Joseph Manchisi, 20, and Rene Charlebois, 15. Peel Regional Police later connected Douglas Donald Moore to the deaths. Reports described Moore as a convicted pedophile and a suspected serial killer from the Meadowvale area.

Robert Grewal and Joseph Manchisi were close friends. Police and later reports stated that Moore believed the two men had stolen drugs and money from him. Later court-related reporting indicated that the theft had actually been committed by a 16-year-old youth who was connected to Moore. Moore allegedly killed Grewal and Manchisi in the garage of his townhouse on Copenhagen Road in Mississauga. Their bodies were later dismembered.

After the killings, Moore received help disposing of evidence. A 16-year-old youth later admitted helping Moore with the aftermath of the deaths. Reports stated that the youth drove with Moore to Quebec and helped bury parts of the victims’ remains in wooded areas near Montreal. The same youth admitted holding the severed heads of both men inside a car wash while Moore cleaned blood from them. In 2005, the youth was found guilty on two counts of accessory to murder after the fact and received a six-month secure-custody sentence. Moore’s former common-law wife was also convicted of accessory to murder after the fact.

Rene Charlebois, 15, was also believed by police to have been killed by Moore. His remains were later found in an Orangeville landfill. Unlike the reported motive involving Grewal and Manchisi, police did not publicly disclose a confirmed motive for Charlebois’ death. Because Moore died before trial, the Charlebois case remained tied to Moore through police suspicion and later reporting rather than a murder conviction.

Moore was arrested on March 27, 2004. At the time, he was facing sexual assault charges involving young boys and was being held at the Maplehurst Detention Centre in Milton, Ontario. On April 2, 2004, Moore was found dead in his cell from an apparent suicide before he could stand trial. Ontario later announced a coroner’s inquest into his death in custody.

Because Moore died before being tried, no criminal court convicted him of the murders of Grewal, Manchisi, or Charlebois. His profile should therefore be written carefully: he was a convicted pedophile and an alleged or suspected serial murderer, but the murder allegations were never tested in a completed trial against him.
