Houston ? More than a year after a horrific bias attack nearly killed him, David Ritcheson masked his pain with a smile, concealing his anguish from the people closest to him, an attorney for his family said Tuesday.

Ritcheson, a Mexican-American who was beaten unconscious and sodomized with a plastic pole by a man shouting “White Power!” in April 2006, leaped to his death in the Gulf of Mexico from an upper deck of a Carnival Cruise ship on Sunday, witnesses said.

Attorney Carlos Leon said Ritcheson had never threatened or talked of suicide and left no note.

“It seemed to everyone that David was climbing back to normalcy in his life,” Leon said at a news conference. “What we’ve learned from this is he just internalized his pain.”

The lawyer said Ritcheson boarded the ship Saturday in Galveston with two friends and the parents of one of the friends. The ship was to have gone to Cozumel before returning July 5. Leon said he was not aware of any incident aboard the ship that might have upset the teenager.

Ritcheson’s parents did not attend the news conference. Leon said they were en route Tuesday to meet the ship at an unidentified small port in Mexico and accompany their son’s body to Galveston. An autopsy will be performed there as part of an investigation overseen by the FBI.

“This comes as a shock to everybody … to his family, to everybody who knew David,” he said.

Ritcheson had endured more than two dozen painful surgeries and had to use a colostomy bag. Perhaps worse, virtually everyone he met knew what had happened to him that terrifying night.

Leon said his client’s physical condition had been improving, and he underwent his most recent surgery just 45 days ago. But he said Ritcheson had rebuffed repeated attempts to persuade him to seek counseling for the emotional and mental scars.
