An Australian convicted double murderer dubbed Mr. Stinky for his offensive body odor pleaded guilty to a series of cold case sex attacks against women and girls — including two who were pregnant — in the 1970s and 1980s, according to new reports.

Raymond Edmunds, now 75, of Victoria, pleaded guilty to 10 charges related to attacks on nine women in suburban Melbourne during a Wednesday court appearance, 7 News reported.

Edmunds, serving two life sentences for the murders of teenagers Abina Madill and Garry Heywood in 1966, turned himself in for the alleged rapes last year, according to the report.

His oldest victim was 51 and his youngest only 14 years old, according to 10 Daily.

He often slipped into his unsuspecting victims’ homes with a mask or stocking on his head — and threatened the women with a knife if they didn’t do what he wished, the court was told.

He’d typically get inside by smashing glass, or cutting the fly screen wire — and once, he even drilled a hole in a door. He told one victim that he’d had his eye on her for two weeks, according to the report.

In some of the sickening incidents, he allegedly assaulted the women as their children slept nearby, according to 7 News.

In one case, Edmunds allegedly barged into the home, told a 31-year-old woman he just wanted to “make love” and said he knew that her young son and daughter were in their bedrooms.

The daughter heard what was going on and revealed that she was petrified, prosecutor Russ Hammill told the court.

“She told [her mother] she had tried to make herself as flat as she could so the accused couldn’t find her,” Hammill said, according to the report.

When defense lawyer Peter Chadwick asked Edmunds why he waited so long to fess up to the crimes, he said he “doesn’t have any reason” — but that he thought the time had come to bring “peace of mind” to himself and his victims.

“Can you think of anything worse than this?” Judge Susan Pellen said after the disturbing details were read, according to the report. “Can you think of anything worse than this? I’m having difficulty finding words to describe how absolutely terrifying this would be.”

Edmunds was sentenced in 1986 “never to be released” for the murders of Madill and Heywood, according to the report.

The monster is also serving time for several other rapes and attempted rapes from the 1960s through the 1980s, giving him a second nickname — the Donvale Rapist, the outlet reported.

He’s set to be sentenced for the latest charges on Sept. 26.
