It’s become like an episode of Murder She Wrote, the US Crime series starring Angela Lansbury.  The family of a cruise ship singer who died mysteriously on the Seven Seas Voyager five years ago has decided to have her body exhumed in a bid to prove she might have been murdered.

Kathy and Mike Kastrinelis, the parents of Jackie Kastrinelis,  claim that her death was never investigated properly and that she might have been murdered, according to The Australian.

The glamourous Ms Kastrinelis was found dead on the luxurious Regent Seven Seas ship in February 2013 near Darwin and her family was left with no choice following the Territoy coroner’s recent denial to hold an inquest into her unexplained death.

“This is really difficult for our family but have to make sure justice is done for Jackie. The investigation into her death was flawed from the start and we are at a loss as to why they did not open an inquest,” Mrs Kastrinelis said.

The Kastrinelis fear that Jackie was murdered following the exposure of a host of errors in the way her case was initially handled. The official reason for the 24-year-olds death was an extremely rare ‘sudden unexplained death syndrome’, and she died in her sleep.

While her family feel uncomfortable with the decision, Mr Kastrinelis told The Australian that they believed this was the only way to get answers.

“It involves taking sections of her organs that in their opinion could retain key markers of drug interactions or proteins and enzymes that might indicate a cause of death.”

Ms Kastrinelis was the lead singer onboard the Cirque Voyager show and was seen the night before, enjoying herself and having a few drinks the night before she died.

On the evening of her death, Ms Kastrinelis was bid goodnight by Jaanus, an Estonian engineer and Daniel, who admitted having consensual sex with the singer about 30 hours before her death.

Also onboard was her ex-boyfriend, Roman, a saxophonist who said seeing Ms Kastrinelis with other men, made him jealous. The police reports revealed Roman had lied in his first interview and the door swipe records from that night do not match accounts provided by the three men.

Despite the coroner’s report, which found that the young woman died from a rare and possible hereditary condition, failed to test for the drug, ketamine.

The report also showed that the investigators failed to collect enough DNA samples to identify the source of male DNA found on Ms Kastrinelis’ underwear.

But there were inconsistencies with the accounts of the last people who saw her alive – the three men.
