Qinxuan Pan, 29, is facing murder and second-degree larceny charges in the death of Kevin Jiang, a second-year Master's student at Yale, who was shot and killed in February in New Haven, Connecticut.
New Haven police named Pan as a person of interest in the case Feb. 10. The search was expanded nationwide on March 1.
U.S. Marshals had secured an international warrant for Pan; Interpol issued a "Red Notice" last month, ABC News reported.
The notice is defined as "a request to law enforcement worldwide to locate and provisionally arrest a person pending extradition, surrender, or similar legal action."
