Investigators were also asking for all business owners to check their outside surveillance video to see if that vehicle was seen on video. Police said they've reviewed a lot of video from Gainesville, but they were seeking areas outside of Gainesville due to the time window being so large.

They are encouraging property owners, residential or business, who may have lime rock roads on their property that are accessible to the general public to search those properties for any suspicious areas of ground that appear to have been disturbed.

"We had figured out some sort of a timeline for Christian on the last day he was seen. Now we're kind of switching gears to Pedro's timeline to figure out exactly where he was and see if we can kind of plug in some holes there," Gainesville police spokesman Ben Tobias said Friday morning.

Anyone who may have captured the SUV on video is asked to call police at 352-393-7670.
