The Palm Beach Post reports:

Speaking in a sometimes shaky voice Monday night to a Jupiter police dispatcher, the mother of Austin Harrouff is heard on a police recording saying her son was “a little delusional…and he feels immortal, like a superhero.” Mina Harrouff made the phone call just before midnight Monday to Jupiter police from her home in The Shores development.

Austin left the Duffy Sports Grill restaurant on Indiantown Road and Island Way in Jupiter about 10 p.m. and was last seen walking north on Island Way, she told police. Austin was wearing a red hat reading “Make America Great Again.” He was carrying a pocket knife, said Mina Harrouff.
