Dennis Allen

Dennis Bruce Allen (7 November 1951 – 13 April 1987) was an Australian drug dealer who was reported to have murdered many victims.

He was based in Melbourne, and was the oldest son of criminal matriarch Kath Pettingill.

Allen, whose solicitor was Andrew Fraser, avoided jail by having info on the corrupt Victorian police at the time.

Allen received a ten-year prison sentence for rape during the 1970s.

It is also reported that he was a major drug dealer in the Richmond and South Yarra areas of Melbourne during the 1980s.

New South Wales Police Detective-Sergeant Roger Rogerson was convicted of supplying heroin in a deal with Allen, but was acquitted following appeal.

Allen avoided capture and prosecution for his crimes by having vital information against several corrupt members of the Victorian police.

His funeral was conducted by Father Peter Norden, a Jesuit priest who performed funerals for three members of the Pettingill family during the 1980s.

He died of heart disease in 1987 in prison custody awaiting trial for murder.

Allen died on 13 April 1987 of heart failure at St. Vincent's Hospital, Melbourne; "pieces of his heart actually broke off after decades of heavy drug abuse".
