The U.S. Marshals Service has increased the reward to $10,000 for information about a man last seen in the Atlanta area who is considered a person of interest in the murder of a Yale graduate student.

Quinxuan Pan, 29, is wanted for questioning in the shooting death of Kevin Jiang, who was killed in New Haven, Connecticut, on Feb. 6, according to the marshals service. Pan also has warrants for two charges: one count of unlawful flight to avoid prosecution and one count of interstate theft of a vehicle.

Pan, a graduate student at MIT, was last seen early Thursday, the marshals said. They believe he is staying with friends or relatives in either the Brookhaven or Duluth areas. While it’s not clear if Pan is still in metro Atlanta, the marshals are continuing to concentrate their search here, agency spokesman Deputy Matthew Duffy told The Atlanta Journal-Constitution.

Jiang was laid to rest earlier Tuesday at the State Veterans Cemetery in Middletown, Connecticut, according to the Connecticut National Guard. He was a 2nd Lieutenant in the 118th Multifunctional Medical Battalion.

Anyone with information about Pan’s whereabouts is asked to contact the U.S. Marshals Service at 1-877-926-8332. Pan is to be considered armed and dangerous, so anyone who spots him should avoid contact.
