The family of a B.C. woman who vanished mysteriously from a cruise ship off the Florida coast is demanding a full investigation, CBC News has learned.

Fariba Amani, 47, of the Vancouver suburb of Port Moody, B.C., was reported missing by her boyfriend, Ramiz Golshani, 46, on the morning of Feb. 29 as the cruise they were on returned to Palm Beach, Fla.

Golshani and Amani had been travelling together on the two-day cruise between Grand Bahama Island and Palm Beach.

Amani's sisters told CBC News she was in a troubled relationship with Golshani and was poised to break it off, but decided to go on the pre-booked cruise.

One sister urged her not to go, afraid she might not make it back.

"It went through my mind right away that she wasn't coming back and that was just a gut instinct," Sahel Amani said.

Last week her fears were realized, she said.

"It’s been a nightmare, it’s been very emotionally disturbing," said Amani's other sister, Sally Amani.

The family has been in contact with the FBI, but "the questions that we have, we're not getting answers to."

They said her presumed death is suspicious, and so far, has been too easily dismissed by the FBI.

"There is something missing. There is information that's not being told. There's something that's not being shared, and someone needs to look into it," said Sally.

Vanished without a trace

The FBI isn't commenting publicly on the case, but said previously that Golshani reported he last saw Amani on board the ship at 1 a.m. ET at the ship's duty free shop.

He reported he went to sleep and when he woke up later she still hadn’t returned to their room. He then reported Amani missing at about 8 a.m. ET as the ship returned to Palm Beach.

A search of the ship turned up no trace of the woman. Her belongings and her passport were found in her room.

The U.S. Coast Guard searched the route taken by the Bahamas Celebration but found nothing.

Ramiz Golshani returned to B.C. three days ago and hasn't talked to the missing woman's family.

He said he told investigators everything he knows about the incident and they have cleared him of any suspicions.

"The FBI has all sides of my story," Golshani said in Port Moody on Monday.

"If I had any per cent of guilt, I would not be out."

Sally Amani said family members just want the mystery cleared up.

"We want to be her voice, her eyes, her feet — everything that she can't do, we want to do for her right now," a tearful Amani said Monday. "Because we know if the tables were turned, she would do exactly that for us."
