First appearance: 1936
When Addie Gothorn was found dead in a hotel, Dick Tracy combined efforts with FBI agent Jim Trailer to find the killer. A bullet hole was apparent in the back of Gothorn's head, but there was no bullet to be found.
Shortly after, the same thing happened to a bellhop at the same hotel. Athnel's eyeglasses had been found at the scene of the crime, which prompted Tracy to plant Junior in disguise as a bellhop to spy on Jones. After Junior barely dodged an ice bullet, Tracy and Trailer break into Athnel's room where they discovered the refrigeration unit that Athnel used to produce his unique bullets.
Athnel returned to his room and found Tracy and Trailer, who were able to keep Athnel at bay until his bullets melted. Athnel was arrested and his guns were taken to Washington D.C. by Trailer for further study.
Athnel revealed that his motive for the murder had been that he had worked once for Gothorn but had many of his ideas stolen, so Athnel sought vengeance.
- The "Hotel Murders" storyline was one of the few genuine mysteries included in the strip, inasmuch as the reading audience learned the clues and the killer's identity along with Tracy.
- Another suspect in the Hotel Murder was Lips Manlis.
- There is no apparent connection between Athnel Jones and the criminal Jones Family or Model Jones.
