An expert can’t determine how a young woman died because her body was crushed in a garbage truck six weeks after she was allegedly murdered, a court has heard.

Marat Ganiev, 53, is accused of killing Isla Bell on October 7, 2024, three days after the 19-year-old was last seen leaving her Brunswick home in Melbourne’s north.

Her remains were found at a rubbish tip in the city’s southeast on November 19.

Ganiev faced Melbourne Magistrates Court via video link today, listening through an interpreter for the start of his committal hearing.

Eyal Yaffe, 58, who allegedly helped him dispose of Bell’s body, also fronted court charged with assisting an offender.

Ganiev is accused of murdering Bell before 2am on October 7, with CCTV allegedly showing him striking the teen in the kitchen of his St Kilda East apartment.

Prosecutors allege he spent two days cleaning his home before Yaffe came over towing a trailer carrying a black fridge.

The pair was allegedly seen removing a different fridge wrapped in plastic onto the back of the trailer on October 17.

Yaffe is accused of driving the fridge to a Caulfield South address, while police say Ganiev then moved the appliance multiple times over the course of two weeks.

Ganiev allegedly left the fridge concealed behind other items in a removalist van on October 30, with another resident locating the appliance on November 18.

The man found a bag inside after smelling a foul odour and threw it in the bin, believing it was a dead animal.

Bell’s remains were discovered in the Dandenong rubbish facility the next day after her disappearance sparked an emotional missing-person appeal from her family.

Forensic pathologist Hans de Boer told the court today he performed Bell’s autopsy but was unable to determine her cause of death due to the advanced state of decomposition.

There was evidence of injuries including lacerations and fractures, but the expert said he could not ascertain if they occurred shortly before death at the time of death or later on.

When defence barrister Ian Hill KC asked if all of the injuries could have been caused by the compactor in the rubbish truck, Dr de Boer replied: “Absolutely, yes”.

Forensic anthropologist Samantha Rowbotham, who also analysed Bell’s remains, told the court the injuries happened at or near the point of death, but she could not be more specific about timing.

She said she had not been informed Bell’s body was compacted in the rubbish truck before the remains were discovered.

Toxicology reports showed the presence of prescription medication and illicit drugs including MDMA in Bell’s system at the time of her death, the court heard.

The committal hearing will continue tomorrow.
