In the early afternoon of October 8, 2014, a coworker of Jin Chen, 39, of Guilderland, New York, United States found the bodies of Chen, his wife and their two children in their home. Police were called to the scene and determined that the family had been killed sometime in the hours before dawn that day by either a knife or a hammer. No suspects have been identified and , the investigation is continuing. It was the first quadruple homicide to occur in New York's Capital District, the region surrounding Albany, the state capital. A considerable amount of forensic evidence, including DNA, has been collected but has not generated any leads; cultural, legal, and linguistic barriers have also made progress difficult despite outreach to other law enforcement agencies in other large U.S. cities, Canada, and China. Investigators have considered links to Chinese American organized crime; there is evidence the Chens may have been involved in illegal gambling and/or the human trafficking of undocumented immigrants from China. They have also considered whether the killings are connected to two other unsolved slayings of Chinese immigrant families elsewhere in the U.S. during the early 2010s. Background Chen Jinfeng (陈锦峰) and his similarly aged wife, Hai Yi Li (李海燕), natives of Houyu in the province of Fujian on the southeastern shore of mainland China, came to the U.S. in the early 2000s. They settled in the Albany suburb of Guilderland, near a take-out Chinese restaurant owned and operated by relatives, where Jin also worked. Two sons, Anthony and Eddy, were born in 2004 and 2007 respectively. They attended the local elementary school. A neighbor told the Albany Times-Union later that the family lived what to him appeared to be a fairly normal life. He recalled the boys playing in the backyard while their mother gardened and kept watch. He recalled having brief conversations with Jin, whose English was adequate enough. Killings Around midday on October 8, 2014, a coworker of Chen's at the King's Wok restaurant where he worked became concerned when he had not reported for work or called to say he would be absent or late. He went to the Chens' house a half-mile (1km) away, on Western Avenue (U.S. Route 20), a busy four-lane highway, and found the bodies. Since his English was extremely limited, he had to ask another coworker, a relative of the Chens, to call 9-1-1 for him.
