Jackson was also was charged with cultivating marijuana at his home in Littlerock, 81km north-east of Los Angeles, where he kept eight dogs, including six pitbulls.

What appeared to be blood was found on the coats and muzzles of the four dogs allegedly involved in the attack.

The victim died on the way to hospital from loss of blood, the LA Times reported, adding that coroner's officials found 150 to 200 puncture wounds across her body.
