Detectives with the Hillsborough County Sheriff's Office last week shared additional security camera footage of who is seen calmly walking away from the area behind the Regency Square shopping center around the time of the incident, WTSP reports.

"Most likely the individual that is seen on that angle, by the times we've collected and determined, would have had to have had at least seen or heard or something if they are not part of the actual incident himself," Detective Greg Thomas told the news station.
