Case Breakers, a nonprofit run by investigative journalist Thomas Colbert, claims to have connected Air Force veteran Gary Francis Poste to the murders and said a FBI agent confirmed to them that he has been considered a suspect since 2016.

“The felon has been secretly listed as the Zodiac ‘suspect’ in Headquarters’ computers since 2016 – with his ‘partial DNA’ safely secured at the feds’ Quantico, Virginia lab,” Case Breakers said in a press release Thursday.

The team said the FBI has a partial DNA sample of Poste’s in its database but has failed to utilize the sample in its investigation into the serial killer responsible for five confirmed murders in northern California in the late 1960s.

[I’m not going to be entirely convinced until we see more evidence. There have been a number of declarations that someone has ID’d Zodiac, and yet here we still are. Could it be Poste? Sure, it *could* have been, but that’s not the same thing as confirming it. The update is still of interest, though. — Ed]
