Here’s what you had to say:

A Statement from Chapel Hill Mayor Mark Kleinschmidt:

The death of Professor Feng Liu as a result of a serious assault and robbery Wednesday afternoon is a horrible tragedy and a loss for the Chapel Hill community.


A safe and secure environment is fundamental to our quality of life in Chapel Hill and, as a community, we must not tolerate such senseless violence. The Town and the University continue to partner on those matters impacting quality of life in Chapel Hill, public safety being chief among them.


Two suspects are currently in custody in the Orange County Jail in connection with this horrible incident. I have the utmost confidence in the investigation that is being conducted by the Chapel Hill Police Department, which will provide information to the public as it becomes available.


I offer my heartfelt condolences to Professor Liu’s family, friends, members of the University community, and all who knew him.

A Statement from UNC Chancellor Carol Folt:

Dear Carolina community:


I am writing in regard to the tragic loss of a member of the Carolina community. As many of you know, Dr. Feng Liu, a research professor in the Eshelman School of Pharmacy, passed away this morning in what the Chapel Hill Police Department is calling a robbery/homicide. This is a tremendous loss to Carolina, and I am heartbroken over this horrible tragedy. My thoughts and prayers are with Dr. Liu’s family, colleagues and friends during this difficult time.


Dr. Liu spent nearly 10 years at Carolina and was dedicated to the success of his students. He conducted important research on gene and drug delivery in the School of Pharmacy. Most importantly, he was a loving husband and father who will be greatly missed.


The Chapel Hill Police Department has arrested two individuals in connection with this tragedy. We will update the University’s Alert Carolina website, http://alertcarolina.unc.edu, as new information is available.


The University is cooperating fully with Chapel Hill police in this investigation. I want to assure you that safety and security of students, faculty, staff and visitors on Carolina’s campus and in the surrounding community is my highest priority.


During this time of loss, the Carolina Community has resources to help us in our grief. We are making counseling resources available. We encourage students to call Counseling and Psychological Services (919-966-3658), and faculty and staff to contact our Employee Assistance Program (877-314-5841), if you would like support.


I encourage all members of the Carolina Community to process their grief and support one another.




Carol L. Folt
