Police said that the surveillance video shows Fucci and Bailey, a 13-year-old cheerleader, walking just after midnight in the Durbin Crossing neighborhood of St. Johns County on the night she was stabbed to death, WTLV-TV reported

Over an hour later, Fucci is seen on the same surveillance camera running in the opposite direction of the woods where he allegedly stabbed Bailey to death, according to police.

Bailey’s body was found May 9 in a wooded area 20 miles south of Jacksonville, hours after she was reported missing. The tip of the knife allegedly used to kill her was found broken off in her skull, and the suspected weapon was found in a pond near her body, authorities previously said. 

Prosecutors also released video of Fucci’s mother allegedly washing blood from his jeans. His mother, 35-year-old Crystal Smith, was charged with evidence tampering in June after turning herself in. 

Smith, 35, was booked into the St. Johns County Sheriff's Office Detention Center on June 5 for tampering with evidence.
