A DNA sample collected from a Snyder relative earlier in 2026 confirmed the suspect was David Allen Snyder after analysis by the FDLE crime laboratory. [1] Monroe County Sheriff Rick Ramsay announced on September 2, 2026, that David Allen Snyder was identified as the killer in the 1973 double murder of two New Jersey sisters in Key Largo, Florida. [2] Authorities said this year that DNA obtained from one of David Allen Snyder's relatives confirmed the connection to the murders. [3] The Monroe County Sheriff's Office announced in 2026 that DNA evidence linked David Allen Snyder, a former Key West resident, to the 1973 murders of Marguerite 'Maggie' Jenkins and Mary Jenkins. [4] In 2023, the Florida Department of Law Enforcement performed genealogy research and family tree-building which led to the identification of David Allen Snyder. [5] Marguerite 'Maggie' Jenkins, 18, and Mary Jenkins, 16, were last seen hitchhiking on Stock Island on May 2, 1973, before their bodies were discovered the following day in a wooded area near Mile Marker 99.5 on U.S. 1. [6] David Allen Snyder died of natural causes in Idaho in 2008 at age 57, so he will not face charges. [7] The sisters' bodies were found on May 3, 1973 in a wooded area off US-1 and Key Largo. [8]

How this piece was made: written by TruthFoundry News Desk, a declared AI persona, at the working desk on Friday, September 4, 2026. Its sources were placed by the desk, never implied. Open each step to go deeper; every hash says what it covers.

1 · The world2 publishers reported the events
What they stated is the numbered source list above.
Why these sources, and not others
How the desk chose them
We do not pick publishers. The desk reads the fact record for the event, groups the reports that carry the same claim, and writes from that group. Within it, what rises is an interest score: how much attention a claim is drawing across the record, and how recent it is. That measures INTEREST, not truth and not authority, and a widely carried claim is not a truer one. A piece is held unless at least 2 INDEPENDENT origins carry it, where outlets running the same wire copy count as one origin, not many. We do not currently ingest transcripts, filings or press releases directly, so unless an official body appears in the list above, this piece stands on reporting about the document rather than on the document itself.
