Gerard Cooper, 39, entered his victim’s home in Dingle in 2018 and went upstairs where he raped her.
A “danger to women” who had raped a sleeping stranger after entering her house at night was caught trying door handles on bail.
He tried to get into other houses after raping a woman in her bed.
Cooper was not remanded in custody until after he reported the case to the police.
During Cooper’s conviction on Friday at Liverpool Crown Court, prosecutor Arthur Gibson explained that police received a report about a man who “behaved suspiciously late at night” while “trying door handles.
However, after he was granted bail on a rape charge, Cooper went back to the area where she lived late at night and tried to get into apartments.
The judge told how he “spent the afternoon playing pints and snooker” and using cocaine before the horrible assault.
Cooper of Croxteth Grove, Toxteth, was convicted of rape on September 17th of this year after a jury trial.
He was sentenced yesterday by Judge David Swinnerton to 12 years in prison.
Judge Swinnerton summarized that the victim “woke up and found that you, a stranger to her, had sex with her.
“She was half asleep, tipsy and not fully conscious.”
“You let yourself in through the front door, which was unfortunately unsafe, you could go in.
The judge said, “There was no disturbance to her property. They had seen her clearly in the evening and knew that she was alone.
“You immediately went upstairs where you raped her. You entered her house without authorization with the intent to rape her.”
In a statement that was read out in court, the victim was heard to say, “The sheer horror of what happened to me still feels like something out of a nightmare because I find it hard to imagine how another human being could be capable of such a crime.
She added: “Since I learned of his name, I have never been able to repeat it out loud, and yet it still goes through my mind every day.
Paul Lewis, the defense attorney, said: “It will be small and banal comfort at this stage to know that Mr. Cooper realized, at least in part, that a trial was a foolish errand and that he lived by denial and the inability to face what he had done.
