There are currently two warrants out for Pan’s arrest. One is in Massachusetts for possession of a stolen vehicle he reportedly stole from that state. Another warrant is out for his arrest in New Haven for extradition for possession of the stolen vehicle he possessed in North Haven, Chief Otoniel Reyes explained.

“We know that this incident has rocked our community, particularly our community in East Rock, particularly our community at Yale University,” Reyes said. “We want you to know that we stand with you as we stand with every one of our community members, and we’re working day and night on this investigation to uncover exactly what happened here and bring the individual to justice.”

Pan is a known graduate student at Mass. Institute of Technology and has affiliations with that university, police said. Jiang’s fiancée, Zion Perry, is also a graduate of MIT. Police said they are exploring every angle of this investigation but are not prepared yet to say whether that connection is relevant to the investigation.

“We are not ruling out that he’s still in Connecticut, but we are exploring leads that he’s somewhere else nationwide,” Chief Reyes added.

MIT sent a statement to News 8 Thursday afternoon saying that while they do not comment on criminal matters, they can confirm Pan and Perry’s connections to the Institute. Pan had been enrolled as a grad student in MIT’s Dept. of Electrical Engineering and Computer Science since September 2014. He finished his undergrad studies at the Institute in June 2014. MIT confirms Perry graduated in 2020.

“We extend our heartfelt condolences to her, the Yale community, and all those impacted in this unfathomably painful time,” the Institute said in a statement. “Matters such as these can be extremely distressing, and MIT encourages members of our community to reach out to any of our many support resources for students and employees.”

Police warn the public Pan should be considered armed and dangerous. If you come in contact with him “extreme caution should be used.” Contact the police immediately. You can remain anonymous.
