A man who allowed his wife to die after he found her tied up and badly injured in the garage of their home in Melbourne’s north has been jailed for at least eight years.

Mohamed Naddaf showed little emotion in the Supreme Court this morning as he was jailed for 11 years, with an eight-year minimum, after pleading guilty to criminally negligent manslaughter.

The offender claims he found his wife, 25-year-old Ashlee Brown, bound and seriously injured in the garage of their Craigieburn home in November 2016.

Justice John Champion, said Ms Brown was found in the passenger seat of the couple’s car after having been subjected to a “deliberate and frenzied assault” and tied up with clothesline wire.

It could not be proven who inflicted Ms Brown’s wounds.

Naddaf didn’t call an an ambulance and instead nursed his wife, feeding her water through a syringe for the next four to five days before she died from her injuries.

Justice Champion said Naddaf treated Ms Brown with a complete lack of respect.

Family members of the victim joined a ring-wing activist group in a protest outside the court, condemning what they claimed was an Islamic honour killing.
