Channel 9′s sister station Action News Jax obtained Fucci’s arrest report, which offers new insight into the case.

The report details that video footage shows Fucci and Bailey walking together around 1:45 a.m. Sunday morning east on Saddlestone Drive. At 3:27 a.m., Fucci was seen walking alone holding a pair of white shoes. Fucci told police he took his shoes off because his feet hurt.

Action News Jax reported that a search warrant was executed at Fucci’s house where police found clothing in his bedroom that “yielded a presumptive positive test result for the presence of blood.” When Fucci was taken into questioning, the arrest report details that he changed his story several times, but ultimately made several admissions.

The arrest report also states that Bailey was found on the south end of a retention pond. She appeared to have significant injury to her head and other trauma. She was found wearing black pants and a black shirt.
