Investigators searching for the person of interest in the February 6 killing of Yale graduate student Kevin Jiang are confident they’ll find him but say they may need to broaden the scope of the search, the New Haven Register reports.

Qinxuan Pan, a graduate student at the Massachusetts Institute of Technology — where he was acquainted with Jiang’s fiancee, Zion Perry —  has not been named a suspect in Jiang’s shooting death, although law enforcement consistently identifies him as “armed and dangerous.”

Jiang, 26, was found shot to death next to his Prius, which had rear-end damage, in New Haven’s East Rock neighborhood, as CrimeOnline previously reported.

Connecticut District Deputy U.S. Marshal Supervisor Matthew Duffy told the Register that search efforts are still focusing on Georgia, where Pan was last seen.

“We’re acting on information provided by the family and an eyewitness account that led us to that area,” Duffy said.

“We’re not ruling anything out,” he added. “There’s always the possibility that by the time we got the information, he’s already out of that area.”

Duffy described the 29-year-old Pan as “a very intelligent kid” but promised “he’s going to get caught.”

“We’re going to catch him,” he said.

The marshals service asks anyone with information to call 877-926- 8332. There’s a $5,000 reward for information leading to his arrest.
