Family warned authorities about Jill Meagher accused Adrian Bayley Court releases a series of CCTV recordings that show Jill Meagher, and her accused killer Adrian Bayley, at various locations on the night she was killed. AUTHORITIES were warned that Adrian Bayley was a risk of attacking a woman before Jill Meagher was raped and killed. The Herald Sun can reveal that months before the 29-year-old ABC employee was raped and strangled, Bayley's parents met authorities and pleaded with them over their grave concerns about his behaviour. The tip-off led to a confrontation between Bayley and his family, with whom he had been living after a court appearance. Bayley then left the family home early last year, and moved with his girlfriend to Coburg, only a kilometre away from where he attacked Ms Meagher just months later. Inside the Bayley police interview On September 22, at 1.30am, he would run to catch Ms Meagher as she walked along Sydney Rd, and abduct and rape her in Hope St, only hundreds of metres away from her Brunswick apartment. Bayley is expected to plead guilty to Ms Meagher's murder today. Bayley's family would not comment, saying they had no intention of speaking publicly about him. After Bayley's arrest, the Herald Sun revealed a government official had tipped him off as police hunted him for Ms Meagher's murder. The tip-off was investigated by police, who it is believed heard it on intercepted telephone calls. No action was taken against the female official. The homicide squad, the Office of Public Prosecutions and Bayley's defence have been at odds after Bayley indicated months ago he wanted the murder charge downgraded to manslaughter. Bayley entered a not guilty plea last month to murder and two counts of rape. The Herald Sun understands the OPP would not consider a manslaughter plea, and Bayley's Legal Aid lawyers have since indicated he will plead guilty today. He has already pleaded guilty to a rape charge. In March, a packed Melbourne Magistrates' courtroom watched as Bayley, dressed in black, sat in the dock behind protective glass while harrowing details of his alleged crimes were outlined. The court heard Bayley accosted Ms Meagher and dragged her into a laneway at 1.38am on September 22, where he raped her and then strangled her. Chief Crown prosecutor Gavin Silbert, SC, alleged Bayley had killed Ms Meagher as she was the only witness to the crime. Ms Meagher's husband Tom outside court after Bayley pleaded not guilty last month. Mr Silbert said Bayley left Ms Meagher's body in the laneway and returned home, where he collected a shovel and returned in his car about 4.20am. He then put Ms Meagher's body in the boot and drove her to Blackhill Rd in Gisborne South, where he buried her, the court was told. After his arrest, Bayley made admissions to raping and strangling Ms Meagher, and directed police to the body, Mr Silbert said. He said he discovered haemorrhages and bruising on her neck along with bleeding in her neck muscles and fractures to her larynx. Bayley wept during an interview with police, during which he told homicide detectives he had to take "responsibility" and thought the death penalty should be reintroduced. "I hope they bring back the death penalty before I get sentenced," he said. But I've done. I can't - I can't do that again for what, 20 years, 25 years. It's no life, man. But she "flipped me off and that made me angry," Bayley said in the interview. Ms Meagher's husband, Tom, left the courtroom early in the proceedings.
