The man sentenced to life for brutally raping and murdering teenage model Sally Anne Bowman has pleaded guilty to sexually attacking two other women.
Dixie, 46, faced new charges as he pleaded guilty to raping a woman, who was just 16, in 1987 after ambushing her in an isolated car park.
A previous hearing was told that after the sex attack he tied the woman to her car and set fire to it, but she managed to escape and raise the alarm.
Appearing via videolink at Southwark Crown Court in London today, Dixie also admitted charges of indecent assault and GBH over an attack on a second woman in 2002.
She was hit on the head with a chef’s steel – normally used to sharpen kitchen knives – before being molested on a flight of stairs, a previous hearing was told.
Dixie finally admitted to police in January 2015 that he killed Miss Bowman, prosecutor Crispin Aylett QC told the court.
Mr Aylett said: “He wrote to to police indicating he wanted to tell them the truth of what had happened to Sally Anne, because at the trial he said that he was not responsible for her murder.
“He also admitted two other serious attacks on women that had taken place some time before.”
Dixie, who appeared from HMP Frankland in County Durham, appeared calm as he appeared on the videolink to admit his crimes, wearing a sports top and glasses.
Dixie, who lived in Australia from 1993 to 1999, had a string of previous convictions before being convicted of Miss Bowman’s brutal murder.
They include being found guilty of indecent exposure and indecent assault in 1988 when he exposed himself to a woman and forced her to the ground.
At his trial, Dixie denied murdering Miss Bowman, claiming he had sex with her after coming across her dead or dying in the street.
His frenzied attack – which included biting her – came minutes after Miss Bowman had parted from her boyfriend after a row in a car.
Dixie then told them about the 2002 attack on a woman near a Croydon railway bridge, who was attacked with a weapon, described as a small crowbar, as she walked home in the early hours of the morning, the CPS said.
After hitting the woman on the head several times, he said “I’m going to kill you”, the court heard.
He dragged her up the stairs and indecently assaulted her before being confronted by a woman living close by who heard the commotion.
Mr Aylett said: “When she asked what was going on, Dixie said ‘nothing, nothing, it’s just a row with my girlfriend’.
“But she (the victim) said ‘help, help, he’s attacking me’.”
Dixie then fled the scene.
Judge Jeffrey Pegden QC adjourned sentencing to September 22.
Rob Davis, from the CPS, said: “These were serious crimes which followed the pattern of Mark Dixie’s offending both in the United Kingdom and abroad.
“These offences took place many years ago and we thank both victims for supporting this prosecution.”
