Deputies have also released video footage depicting three individuals thought to be the suspects walking out of an alley from East Cliff Drive onto Pleasure Point Drive, near Atre's home.
Investigators are asking members of the community to take a close look at the clothing, mannerisms and "walk" of the individuals in the video to see if they recognize someone.
Anyone with information that could lead to the identification of the suspects involved in Atre's disappearance is asked to contact Sgt. Ainsworth at (831) 454-7635.
