Horng-Chang Ke, 49, also known as Evin Ke, gradually disappeared from his life in State College, Pennsylvania after a period of housing instability. He was evicted from a residence on Waupelani Drive in 2013. In 2014 Penn State University Police encountered him in a campus building and noted he appeared to be experiencing homelessness; that was the last confirmed in-person sighting, though the exact date is unclear.

Contact with family dwindled afterward. The family last spoke with him by phone in March 2016. His final known social media activity, on Facebook under the name Evin Ke, was a post in October 2016. There have been no confirmed sightings or direct contacts since then, and his whereabouts remain unknown.

Did anyone in State College know Horng-Chang or Evin, or have information about where he might have gone after 2016?
