Man jailed for life for killing ex-partner

A man who bashed his former partner with an axe and mop handle, then had sex with her and left her to die in her WA home, has been jailed for at least 21 years.

Kevin James Corbett, 51, murdered 36-year-old Charmaine Winmar at her Narrogin home, in the Wheatbelt region, in May 2013.

He was sentenced in the WA Supreme Court on Friday to life behind bars.

Corbett caught a bus from East Perth to Narrogin, leaving abusive graffiti related to Ms Winmar along the way, before attacking her in her home, the court heard.

Ms Winmar suffered injuries to her head and chest and Corbett also took photographs of himself having sex with her as she lay motionless on a mattress.

During his trial, Corbett tried to blame Ms Winmar's death on her new partner, Richard Penny, despite him also being injured in the attack.

With time already served, Corbett will be eligible for parole in 2034.
