London, Aug 12 (IANS) A Briton who murdered his wife due to his ‘twisted obsession for sex’ has been sentenced to 25 years in jail.

Just days before their divorce, 32-year-old Brent Mott killed his wife Kate, Daily Express reported Thursday.

Brent attempted to cover up the killing by staging a car accident. He took Kate’s body to a remote country lane and placed it in the driver’s seat before shattering the windscreen to suggest a crash.

A postmortem examination showed that Kate was strangled and died before she was dumped in the family car in Southport, Merseyside.

Mott had even raped her during a confrontation when their two children were asleep. The couple hadn’t had sex for 18 months.

He claimed it was consensual and described it as a ‘a last fling’.

A judge, however, said that Kate would ‘never have agreed’.

‘You (Brent) murdered her for sex. It was done in your heightened sexual frustration borne out of your own twisted obsession toward sex,’ a justice official was quoted as saying.
