New surveillance video shows a missing Pittsburgh ICU nurse on the night that he disappeared.

Paul Kochu, 22, is seen on video walking with a towel wrapped around his hand, which he had injured earlier. Kochu disappeared on Dec. 16 after a night out with friends.

Kochu’s mother, Ellen, said that she got a call from her son’s roommates that he had not been seen all day. She went to Pittsburgh when Kochu didn’t show up for his job at Allegheny General Hospital.

Watch the surveillance video and an interview with Kochu’s mother above.

Anyone with information on Kochu is urged to call police at 412-323-7141 or 911.
