The Federal Bureau of Investigation will pay $30,000 for information leading to the arrest of a fugitive wanted in connection with the murder of five men at Boston's Chinatown 30 years ago.
Hung Tien Pham was last seen in Thailand around the mid- to late-1990s.
Pham, who is now 60, was indicted in 1991 for five counts of murder, one count of assault using a deadly weapon with intent to murder, one count of conspiracy and one count of illegal possession of a firearm.
Pham is wanted for "one of the bloodiest massacres" in Boston's history, the bureau's director in Boston said Tuesday - the 30th anniversary of the killings.
Pham and two others shot six men while they were playing cards at a social club on Tyler Street in Boston Jan. 12, 1991, according to the bureau.
Five of the men died, while the sixth survived and identified the suspects - two of whom were arrested in China in 1998.
The survivor became a witness in the trial of two of the shooters. They were convicted and sentenced to life in prison. Siny Van Tran and Nam The Tham were found guilty of first degree murder in 2005.
"We are renewing our call for the public's assistance in locating longtime fugitive Hung Tien Pham," Joseph Bonavolonta, special agent in charge of the bureau in Boston, said.
Pham was born in North Vietnam and is fluent in English, Vietnamese and Chinese. He was a permanent resident of the U.S. and lived in Dorchester at the time of the killings.
"This cold-blooded killer has been on the run for 30 years and we're hoping this reward will incentivize anyone with information on Pham's whereabouts to come forward," Bonavolonta said.
