The search for missing Marvel and DC comic book artist Norman Lee has been called off, CNN reports. Lee is presumed dead.

Lee, 47, was reported missing on Thursday during a snorkeling trip with his wife off the coast of Grand Cayman. He was best known for his ink work on X-Men, The Avengers, Starman, Wolverine Annual, and Supergirl. Friends, fans, and colleagues have taken to Lee’s Facebook page to share memories and artwork.
