Serial rapist Adrian Ernest Bayley raped three more women, including two just months before he murdered Jill Meagher.

Bayley, 43, raped an 18-year-old sex worker in his car in St Kilda in 2000.

He raped another 25-year-old sex worker in April 2012, in near identical circumstances.

He also raped a Dutch backpacker in July 2012, two months before he attacked Ms Meagher, after telling her she was in danger and convincing her to climb into his car for safety.

Bayley picked up all three women in St Kilda and drove them to a secluded laneway where he parked with the passenger side door pressed against a fence, blocking their escape.

He contested each charge but juries found him guilty in three separate Victorian County Court trials.

Bayley has now been found guilty of raping 10 women and attempting to rape two more.

He is serving a life sentence with a 35-year-minimum for the rape and murder of Ms Meagher in a Brunswick laneway in September 2012.

His attack on Ms Meagher led to a review of Victoria’s parole laws, after he was mistakenly allowed to remain on the streets.

Bayley was released from prison on parole in 2010, but that should have been cancelled after he was convicted of assaulting a man in February 2012.

Instead he appealed the assault charge and was released on bail, leaving him free to rape the 25-year-old, the backpacker and kill Ms Meagher.

Bayley was found guilty of raping the 18-year-old in July 2014, but suppression orders prevented reporting of the case until he faced the two other trials this month.

Judge Sue Pullen lifted the orders when the final jury returned its verdict on the backpacker’s case yesterday.

In June 1991, a 19-year-old Bayley was jailed for five years, with a three-year non-parole period, for raping a teenager and attempting to rape two more women.

He was jailed again in April 2002 for 11 years, with minimum of eight, for 16 charges of rape against five victims.

Judge Pullen will sentence Bayley at a later date.
