Mr Tascas’ mother Pamela Tascas says the finding has confirmed the family’s belief her son was killed.
“I’ve waited 14 years for [my son] to walk up the path and he hasn’t come,” she said. “We’ve waited all this time.“
At the time of Mr Tascas’ disappearance in early October 2005, he had been living with a man named Lawrence Butler.
In 2009 Mr Butler was sentenced to 23 years in jail for his housemate’s murder, before his conviction was quashed on appeal.
The alleged killer was later retried for manslaughter before a jury found him not guilty.
Mr Tascas’ family say they are now forced to leave restaurants across Geelong as they bump into the man accused of being responsible for the 27-year-old’s disappearance.
During a summary inquest on Tuesday, the Coroners Court heard Mr Tascas, also known as Trevor John Van Der Wel, disappeared from Geelong’s east some time between October 7 and 10 in 2005.
After being released from prison in 2000 for a series of burglaries and thefts, he had returned to Geelong to reconcile with his mother.
But he spiralled back into cannabis and methamphetamine use and lost contact with her.
In 2005 he moved into a home in Thatcher Court, Whittington, with Mr Butler. But within weeks he suspected his new housemate was “snooping” in his room and they began to argue over money.
During the Bathurst V8 Supercars weekend in early October 2005, Mr Butler’s new girlfriend Jodi Harris attended the property and asked to use the shower.
She told police that there, in the bath, she found a large white hessian bag.
“The water was red in colour and I immediately thought it was blood mixed in with the water,” she told police.
Tuesday’s inquest heard that when Ms Harris questioned her partner about the bag’s contents, he said it was fish.
In statements to police, Ms Harris said she later walked past Mr Tascas’ bedroom and saw a blood-soaked sheet. When she told her boyfriend she wanted to leave, he allegedly replied: “You know what you’ve seen, you are now a part of this.”
Ms Harris said her boyfriend then dragged the bag outside into a large barrel.
Days later Ms Harris said she returned to the Whittington home to find “bone fragments” in the ash, some the size of fingers.
The inquest heard that several days later the pair drove Mr Tascas’ maroon Holden Commodore to Queensland, where it was sold for cash.
Months later Ms Harris withdrew $10,000 from the missing man’s bank accounts, giving some to her ex-husband to purchase a blue sports car.
The coroner Mr Olle acknowledged the police investigation was thorough.
“While Mr Tascas’ body has not been located, there is sufficient evidence to satisfy me that his disappearance is due to him being deceased and that the death is a suspected homicide,” he said.
Sister Kirsty Tascas said the family would never give up hope of finding out what happened to her older brother.
“Hopefully it’s chewing [the killer] up inside.”
Mr Tascas’ father Joe Van Der Wel died of a heart attack last year, never knowing what happened to his son.
