He was found guilty in 2001 of sexually abusing his daughters, Jeannie, born in 1981, and Anne Marie, born in 1983, between 1995 and 1998, and was sentenced to seven years in jail in a facility 110 kilometers northwest of Montreal. On 24th May 2006, Hilton was granted parole and was freed on the 20th June of the same year.
Hilton's daughters have written a book, Le Coeur au beurre noir (The Heart with a Black Eye), describing their abuse in detail. In September 2004, a Quebec judge lifted a publication ban on the identities of the daughters so they could publish the book. An English translation is in progress.
Hilton Jr. was granted early parole on May 25, 2006 and was released the following month having served two-thirds of his sentence. He made his return to the boxing ring in May 2007 and won a unanimous decision.
On August 20, 2007, Hilton was arrested by police and returned to jail for breaching conditions of his release. It was reported that Hilton assaulted his wife and made threats. He was acquitted on the charges of assault and death threats but remained detained pending the decision of Commission nationale des libérations conditionnelles due to his conditional release violations.
