Ricardo is a comic book and mystery novel writer, toy buff and life-long Scooby-Doo fan. His projects include Legends of the Dark Knight and Teen Titans Go! for DC Comics, Boo the Dog for Dynamite, and Spotlight Soccer (Sports Illustrated Kids) for Stone Arch Books. His Elvis Sightings Mystery series has received rave reviews for its humor and inventive plots and his original graphic novel A Hero's Death, funded on Kickstarter and then published by IDW, has been hailed as "heart-warming yet heart-breaking and magical."
