AN autistic teenager allegedly murdered by two older women suffered two fatal stab wounds and tried to fight off his attackers, a Perth jury has been told.
Aaron Pajich, 18, was stabbed in the neck, severing a jugular vein, and a deep knife wound to his chest damaged numerous vital organs, including his liver and lungs, forensic pathologist Jodi White told the Supreme Court of Western Australia on Monday.
She was giving evidence at the trial of Jemma Lilley, 26, and her housemate, Trudi Lenon, 43, who are accused of murdering Mr Pajich in June last year.
The pair have pleaded not guilty but Lenon, who went to the same TAFE as Mr Pajich and whose 13-year-old son Cameron was close friends with him, has admitted lying to police and being an accessory to the crime.
Dr White, who performed an autopsy on Mr Pajich, described how he had suffered numerous wounds.
The fatal neck and chest wound could have individually killed him through massive internal bleeding.
There was a second, deeper but non-fatal knife wound on the left side of his neck that might have damaged his spinal cord.
There were also marks on the right side of his neck, indicating attempts to garrotte Mr Pajich with a wire that broke.
Dr White said numerous wounds on his hands indicated “defensive wounds” consistent with someone trying to defend themselves against a knife attack.
Prosecutor James McTaggart has alleged Mr Pajich’s murder was a “thrill kill”.
Witnesses have told the court how Lilley was obsessed with serial killers.
She even gloated about killing Mr Pajich to a colleague Matthew Stray at the Perth Woolworths supermarket she worked at, the trial has previously been told.
CCTV footage taken from a camera at the women’s Orelia house shows the accused and Mr Pajich entering through the back door on the day he went missing.
His body was later found in the backyard buried under a roughly poured concrete slab overlaid with red tiles.
