A Northampton man is started a 12-year jail term after raping a woman he had found collapsed in the street.
Franklyn Kehinde Coker, aged 25 of Northampton, was sentenced at Amersham Crown Court on Friday.
A spokesman for Thames Valley Police said Coker found the woman collapsed in the street in Bletchley one night in 2015.
"He raped the victim before dropping her off at a local address.
"The woman had no recollection of the events the following day and reported her concerns to the police," the spokesman said.
Coker was charged on June 10 last year and pleaded not guilty.
The first trial, which lasted five days, took place at Amersham Crown Court in October 2016 and resulted in a hung jury. A second three-day trial took place at the same court in January this year and resulted in a unanimous verdict of guilty.
Investigating officer, Detective Sergeant Phil Walsh of Milton Keynes Force CID, said: "Coker committed this horrendous offence whilst the victim was vulnerable and unable to defend herself.
"Due to the victim's courage in coming forward and giving evidence, we were able to thoroughly investigate and ensure that this dangerous offender was brought to justice.
"The 12-year prison sentence sends a strong message that violent and sexually motivated crimes will always be dealt with robustly by Thames Valley Police, the Crown Prosecution Service and the courts. Coker will now serve a significant amount of time behind bars."
