Roberta Musquiz Pagan, a 35-year-old woman from Las Vegas, was last seen while aboard the Carnival cruise ship Elation during a voyage between Mazatlan and Cabo San Lucas in late January 2003. Reports place her disappearance on January 31, 2003, though some agencies list January 26. She was last seen leaving her cabin around 1:00 a.m., reportedly to take a walk, and did not return. The ship docked in Cabo San Lucas the next day but there is no indication she disembarked there; the formal investigation began when the Elation reached San Pedro, California.

Pagan is described as Hispanic, 5 feet 5 inches, 160 pounds, with brown hair and brown eyes. Distinguishing marks include a scar on her left ankle, a mole on her right cheek, and scars on her left thigh and breast from a dog attack about a decade earlier. She was reportedly wearing a cream-colored shirt and shorts set with dolphins and the words Puerto Vellarta, and black flip-flops. Her husband and five-year-old son were aboard; the husband has been ruled out as a suspect. The U.S. Coast Guard could not assist because the disappearance occurred in Mexican waters. Authorities have said there is no evidence of foul play, though family and friends disagree and have questioned ship security. The FBI is investigating.

If anyone was on the Elation that night or remembers seeing Roberta leaving her cabin, please share what you know.
