Judge sentences San Francisco Chinatown gang leader 'Shrimp Boy' to life in prison

A judge has sentenced a San Francisco Chinatown gang leader known as "Shrimp Boy" to life in prison for killing a rival.

Raymond Chow was sentenced Thursday by U.S. District Court Judge Charles Breyer.

His prosecution was part of a major organized crime investigation in San Francisco's Chinatown that also brought down a state senator.

Prosecutors say Chow killed a rival in 2006 and took over a Chinese fraternal group that had members that engaged in drug trafficking, money laundering and the sale of stolen cigarettes and some top-shelf liquor.
