A man wanted for questioning in the murders of two Chinatown women last month who was pulled off a plane Monday evening used cash to pay for a one-way ticket to Hong Kong, law enforcement sources tell NBC 4 New York.

The man, identified as Songfei Li, was tracked to and pulled off a Hong Kong-bound Delta flight at JFK Airport after authorities put out a bulletin indicating he was wanted for questioning in the June double homicide and fire on Henry Street.

Li was previously arrested in Brooklyn over an incident with a cab driver. He remains in police custody on assault charges in connection with that case while the Manhattan district attorney's office decides if there is sufficient evidence to charge him in connection with the Chinatown slayings, law enforcement sources said.

Police say the two women were found shot in the head after authorities extinguished the blaze at the seven-story building. One victim was in her 50s and the other was in her 70s, police said.

Li may also face new charges in the Brooklyn case where he allegedly threatened a cab driver with a gun, law enforcement sources say. Li was previously charged with menacing, harassment and criminal mischief in that case.
