As Yonglu Che ’13 continues to recover from his injuries, Yale and the state police are investigating last Sunday’s accident, when Che was struck by a Yale Police cruiser.

Connecticut State Police Lt. Paul Vance said troopers and technicians of the state’s Accident Reconstruction Unit are leading the inquiry. Officials said they could not estimate how long the investigation would take and would not discuss possible consequences until the reviews are completed.

In the meantime, Yale Police Officer Willie Guilford, who was driving the car that hit Che, is expected to return to work Thursday or Friday. Yale Associate Vice President for Administration Janet Linder, who oversees the Yale Police, said in an e-mail that she was concerned for the recoveries of both Che and Guilford.

“While [Guilford] didn’t suffer any physical injuries, I know this has to be a deeply traumatic experience for him,” she said.

In a Sunday e-mail to Berkeley students, Master Marvin Chun said Che was in good spirits and expected to return to school for the fall semester.

University spokesman Tom Conroy said the University is in contact with Che’s family and “will be providing any and all support and assistance needed at this most difficult time.”
