The jury in the trial of a man accused of sexually assaulting and strangling a teenage girl in north London has retired to consider its verdicts.
Zakk Sackett, 20, of Outram Place, Islington, has denied murdering and raping Jessie Wright in March 2010.
The 16-year-old's body was found behind flats where Mr Sackett, who has learning difficulties, lived.
He told the Old Bailey she consented to sex but died accidentally after he got "his good friend" in a head lock.
His barrister, Jeremy Dein QC, said earlier in the trial it had to be accepted that Jessie was killed by Mr Sackett.
But they were "jostling together" and her death had not been intentional, he said.
However, prosecutors told the court Mr Sackett "was obsessed" and the teenager "didn't want to know".
He strangled her and dumped her body in an "out-of-the-way" alley, the jury heard.
