A Massachusetts man who the FBI says has traveled to Yemen and Pakistan for training in how to kill American soldiers now has a $50,000 price on his head.

Ahmad Abousamra, 31, last lived in the U.S. in a tony Boston suburb and has relatives in Detroit. He left the United States in 2006 and may now be living in Aleppo, Syria, with his wife, at least one daughter and other relatives. He was indicted in 2009 for taking multiple trips to Pakistan and Yemen to seek jihad training and has been charged with conspiracy to provide material support to Al Qaeda.

“Knowing that the public is the FBI’s best ally in finding fugitives, today we’re requesting your assistance to locate Abousamra,” said Richard DesLauriers, special agent in charge of the FBI’s Boston office.
