Dr Glennon E. Engleman (c.1928-1999) was a St Louis dentist who moonlighted as a hitman, concocting and carrying out at least seven murders for profit over the course of 30 years.

He was already serving two life sentences in a Missouri jail when he pleaded guilty to the murder of a man and his parents in a separate contract killing.

Engleman was a sociopath; he once stated that his talent was to kill without remorse and he enjoyed planning and carrying out killings and disposing of the remains, in order that it would net him financial rewards.

Methods used to kill his victims included shooting, bludgeoning with a sledgehammer and car-bombing.

Engleman died in prison of a diabetes-related condition in 1999. The exact number of his victims is unknown as he took this information to his grave.

Corbin Bernsen played Engleman in Beyond Suspicion, a 1993 telemovie loosely based on the killings.
