Captain Glenn Ryder was a captain in the Jackson County Sheriff’s Department (Mississippi) who became the first law‑enforcement officer to interview Charles Hickson and Calvin Parker after their reported abduction on the Pascagoula River on October 11 1973.

Ryder conducted an extensive interrogation of the two men, secretly recording their conversation to assess their credibility. He later stated, “We did everything we knew to try to break their stories. If they were lying to me, they should be in Hollywood.” Ryder’s investigation concluded that Hickson and Parker were not hoaxers and appeared genuinely traumatized by their experience. His official report helped establish the Pascagoula incident as one of the most credible multiple‑witness abduction cases on record.
