 The woman plunged from a deck of the Royal Princess early Tuesday, landing so hard on a lifeboat she shattered its windows, the publication reported. 
 
 Passengers saw the “muscular” man choking the woman, Diario noted. Authorities hope an autopsy will reveal if she died from the fall or from asphyxiation, it said. 
 
 Princess Cruises confirmed to USA Today that a woman had died on the vessel, but did not share further details of the incident, the outlet stated. 
 
 The cruise company shared the following statement with Newsweek: "A 52-year-old, American, female guest passed away early Tuesday morning aboard Royal Princess as the ship was en route to Aruba.

 On November 7, an elderly woman died after falling from a tender platform on a Holland America Line cruise ship traveling in the Cook Islands. The woman was pulled alive from the water before losing consciousness on the platform, the cruise company told Newsweek. Although the circumstances of the death are still unclear, passengers reported rough seas at the time. 
 
 In October, A Royal Caribbean cruise ship recently made an emergency stop after taking on water. “We were experiencing rough sea last night, and then in the early hours last night we heard a bang,” one passenger told The Express. “We were told there was a minor technical fault... But it was a major problem and we were on a ship hundreds of miles from land taking on water.”

 The 52-year-old woman, described only as a "female guest" on the Royal Princess from the U.S., died under unclear circumstances. The ship was on a seven-day cruise from Fort Lauderdale, Florida, to Aruba. 
 
 The victim's brother, Tony Rodriguez, identified the woman to ABC News as American citizen Almarosa Tenorio. 
 
 “Almarosa was a very loving daughter, sister, mom and grandmother with a good heart," Rodriguez said in a statement. "Her passion was teaching and working with children. She had a vivacious personality with a smile that would light up a room. We are sad that she was taken from us at such a young age. She will be missed by all that knew her." 
 
 Tenorio lived with her son, a student at the University of South Alabama, according to a GoFundMe campaign set up for the family. 
 
 No cause of death has been reported, but her death was ruled unnatural, Aruba Public Prosecutor's Office spokeswoman Ann Angela told ABC News. The prosecutor's office will not be releasing the details of the autopsy. 
 
 The woman's husband was questioned as a witness and is not being investigated at this time as a suspect, Angela said. 
 
 Angela said the death is being investigated at every angle but would not disclose whether it's being considered a homicide. 
 
 "The incident was reported to the FBI and local authorities and the local authorities met and boarded the ship upon arrival in Aruba," Princess Cruises said in a statement Wednesday. "We are cooperating fully with the investigating authorities, including the FBI." 
 
 The ship, which can carry up to 3,560 passengers, was expected to return to South Florida on Saturday. The Royal Princess is set to undergo a $15.9 million makeover in just a matter of weeks. 
 
 "We are deeply saddened by this incident and offer our sincere condolences to the family and those affected," the cruise line said. 
 
 The woman's name and hometown have not been released. 
 
 The death was the second announcement of a person being killed on a cruise ship on Wednesday. Holland America announced a 70-year-old woman was killed when she fell into the water in the South Pacific while trying to move between deck and a smaller boat.

– Not many details are out yet, but it's a big enough story that the FBI is now involved. ABC News reports that both local and federal authorities are investigating the Tuesday death of a 52-year-old woman on Princess Cruises' Royal Princess cruise ship. The vessel had departed its Florida port in Fort Lauderdale and was on a seven-day journey, with Aruba as one of its destinations. That's where police boarded the ship after the incident was reported. "We are cooperating fully with the investigating authorities, including the FBI," Princess Cruises noted in a statement. CBS News and USA Today report that some Aruba news outlets are saying authorities may be treating the incident as a possible murder; an island police update on Facebook Tuesday notes it doesn't appear to be a "natural death." Per Newsweek, one outlet gets even more detail, reporting that the woman fell off the boat's top deck after she was seen scuffling with a "muscular" man who appeared to be choking her. A person claiming to be a passenger posted in a cruise forum that passengers weren't immediately allowed off the ship in Aruba, and that cops and forensic technicians had come onboard. "We are deeply saddened by this incident and offer our sincere condolences to the family and those affected," the cruise line added in its statement. The ship is set to arrive back in Florida on Saturday. (A "tragic accident" on another cruise line last month.)
