Even though video surveillance footage from the cruise ship which Mindy Jordan fell to her death from shows no foul play, her mother still wants the FBI to investigate.

American mother-of-two Mindy Jordan, of New Jersey — plunged from the Norwegian Dawn 45 miles northeast of Atlantic City on May 11 after witnesses said she was climbing from balcony to balcony.

The FBI, who have been investigating the case, says no foul play was involved. But Ms Jordan's mother Louise Horton, of Bordentown, New Jersey, is not satisfied, The Associated Press reports.

The report, posted on newsday.com said: "Miami-based Norwegian Cruise Line says surveillance video from an interior hallway shows that Jordan was alone in their room from 7.36 p.m. until 7.53 p.m., when an exterior camera shows her falling from the balcony.

"The cruise line has said its preliminary investigation indicated that Jordan, a 46-year-old nurse and mother of two teenagers, slipped while trying to climb over from her room's balcony to a neighbouring balcony where her boyfriend, Jorge Caputo, was visiting with friends."

Mrs. Horton, told The Associated Press that the cruise line told her about the surveillance video, which hasn't been made public and that she doesn't believe the video shows exactly what happened leading up to the fall.

"If that happened, how would they know that?" she was quoted.

The report continued: "Cruise line spokeswoman AnneMarie Mathews said that the exterior video shows the railing of the balcony, but not the area inside of that.

"She said she had not seen it and was not certain whether it shows what Jordan was doing before she fell. Mark Mershon, an FBI assistant director, told Fox News that the video quality is not clean enough to determine exactly what happened.

"But, he said, 'The information that we have acquired does not suggest a crime, but that is not definitive.'"

Mrs. Horton had declined the cruise line's offer to fly her to Bermuda to see the video and pick up her daughter's belongings.
