A Queensland man witnesses believe could be behind the murder of a teenage girl in 1989 says anyone who has spoken against him since her death is a liar.
During his two-day testimony at an inquest into the murder of Annette Mason at her Toowoomba home, suspect Michael Laine lashed out at witnesses who linked him to the crime.
Mr Laine denied threatening witnesses to stay silent over the years and rubbished evidence he had destroyed clothes after the 15-year-old was killed, went to her house where he found her body or discussed coming up with an alibi.
"I don't know whether perjury comes out of this case or anything, or whether anybody can get charged after it, but there is a few of these imbeciles (who) seriously do need to be charged," he said on Wednesday.
"They can't just go around saying this s***."
It comes after the 53-year-old complained his reputation had been tarnished by rumours he murdered the girl.
Mr Laine became a person-of-interest after Annette was found raped and beaten to death in her bed in a share house five doors from where he lived at the time.
He was interviewed by police on the day her body was discovered but struggled to recall events from that period at the inquest and said other witnesses had concocted stories about him.
"Part of these statements, I don't deny are right, but its like they pulled something from here and something from there and then put a whole heap of crap in between and expect you to swallow it," he said.
He denied being an associate of Allan McQueen, also known as Allan Gill, a second suspect who was allegedly seen with blood on his clothes about the time Annette was killed.
Witnesses including serving and former police have told coroner Terry Ryan Mr McQueen admitted to her death on multiple occasions.
A police officer who was at the crime scene is expected to give evidence at the inquest on Thursday.
