John Schneeberger was raised in Northern Rhodesia (now Zambia) and received his medical degree at Stellenbosch University in South Africa. In 1987, he moved to Canada. He lived in the town of Kipling, Saskatchewan and practised in the Kipling Medical Centre.

In 1991, he married Lisa Dillman who had two children from a previous marriage. Schneeberger and Dillman had two daughters during their marriage.[1] In 1993, he acquired Canadian citizenship and still retained his other citizenship.
Rape case

Schneeberger was accused of serious sexual crimes, and convicted after successfully foiling DNA tests several times.[2]

On the night of 31 October 1992, Schneeberger sedated his 23-year-old patient, Candice, and raped her. While Versed—the sedative he used—has a strong amnesic effect, Candice was still able to remember the rape. She reported the crime to the police.[3]

Schneeberger's blood sample was, however, found not to match the samples of the alleged rapist's semen, thus clearing him of suspicion. In 1993, at the victim's request, the test was repeated, but the result was negative, as well. In 1994, the case was closed.[3]

Candice, still convinced that her recollections were true, hired Larry O'Brien, a private detective, to investigate the case.[4] He broke into Schneeberger's car and obtained another DNA sample, which, this time, matched the semen on the victim's underwear and pants. As a result, a third official test was organized. The obtained blood sample was, however, found to be too small and of too poor quality to be useful for analysis.

In 1997, Lisa Schneeberger found out that her husband had repeatedly drugged and raped her 15-year-old daughter from her first marriage. She reported him to the police, who ordered a fourth DNA test. This time, multiple samples were taken: blood, mouth swab, and hair follicle. All three matched the rapist's semen.

He was found guilty of sexual assault, of administering a noxious substance, and of obstruction of justice, and received a six-year prison sentence.[6]

The College of Physicians and Surgeons of Saskatchewan stripped Schneeberger of his medical license and his wife divorced him. She also complained about him to the Canadian immigration authorities.

In 2003 Schneeberger was released on parole after serving four years in prison. He was stripped of his Canadian citizenship (granted in 1993) due to having obtained his citizenship illegally. He had lied to a Canadian citizenship judge claiming that he was not the subject of a police investigation. In December 2003 Canada authorities revoked his citizenship and ordered his deportation. Being a permanent resident of South Africa, he was returned there in July 2004. He moved to Durban to live with his mother.

I Accuse is a 2003 drama film directed by John Ketcham. It is based on the case of Dr. John Schneeberger, a Canadian doctor convicted of using drugs to rape two patients.
