Jackie Kastrinelis, Cruise Ship Singer Mystery: Found Dead on Regent Seven Seas Voyager Ported in Australia, Death Remains Unsolved [VIDEO]

Reports confirm that 24-year-old Massachusetts native Jackie Kastrinelis, a singer aboard the Regent Cruise Lines' Seven Seas Voyager, was found dead in her cabin while the ship was docked in Australia on Sunday, Feb. 3. The details surrounding Kastrinelis' unfortunate passing still remain a mystery, although authorities have ruled out any foul play. Kastrinelis' family members are in utter shock and disbelief, and hope that authorities are able to provide more revealing information about the young University of Hartford graduate's death sometime soon.

Regent recently released the following statement concerning the luxury cruise ship singer's death:

"The Regent Seven Seas Cruises' family is deeply saddened by the unexpected passing of Jackie. Our hearts and prayers go out to her family and loved ones."

According to several reports, Kastrinelis' lifeless body was discovered aboard the Regent Seven Seas Voyager after the ship docked in Darwin Harbor, Australia on Sunday morning. Authorities initially treated the young woman's cabin as a crime scene, but later determined that there was nothing suspicious and that murder was not a factor. Even so, Kastrinelis' death remains a total mystery. "The Crime Division is no longer treating the death as suspicious," said Det. Superintendent James O'Brien of the Northern Territory Police, according to the Daily Mail. "Further toxicology results will be analyzed in due course to determine the exact cause of death."

Cruise Law News claims that Kastrinelis, a lead singer for the talent cruise ship provider Jean Ann Ryan Productions, suffered a head injury during rehearsals on Saturday night and was given medication by a ship doctor. It could still take weeks for any conclusive news from the toxicology tests and autopsy report.

The website also claims that Kastrinelis was only aboard the Seven Seas Voyager for a short period of time, but had worked on other Regent ships since 2011. Jean Ann Ryan, who runs the production firm, said that Kastrinelis was a "ray of sunshine, a life force and a beautiful person."

The Seven Seas Voyager holds approximately 447 crew members and 700 passengers. 

According to the Eagle Tribune, Kastrinelis' family was set to arrive in Australia on Thursday (Feb. 7) to claim the young woman's body. They are hoping to solve the mystery behind Kastrinelis' unexpected death, and aren't just relying on police work to do so. Chris Stein, Kastrinelis' uncle, has been named the family's spokesperson and is collecting tips and any further information that may help solve the mystery of the cruise ship singer's death. Anyone that might have any clues are urged to contact Stein at chris.stein1@gmail.com or 508-696-8968.

Thoughts and condolences go out to Kastrinelis' family, friends, and colleagues during this time of tragedy.
