New federal and state reports reveal details in Dylan Harrison drowning probe

Authorities investigating the August 2025 death of 12-year-old Dylan Harrison said federal and state reports released Feb. 24, 2026 contain new details tied to the open-water scuba certification course at The Scuba Ranch near Terrell. The reports mark the latest development in an investigation officials have continued to develop since the drowning.

Dylan Harrison was enrolled in an open-water scuba certification class at The Scuba Ranch near Terrell in August 2025 when he drowned, local records show. The initial response to the drowning prompted a multiagency inquiry; the separate federal and state reports issued Feb. 24, 2026 review aspects of that training exercise and the circumstances surrounding Dylan’s death.

The federal and state reporting in the past week highlighted specifics tied to the certification activity at The Scuba Ranch, according to investigators working the case. Authorities overseeing the probe have been comparing operational details from the Scuba Ranch course with applicable safety and training standards as they assess what happened in August 2025.

Collin County neighbors and families in the Terrell area learned of the new reporting on Feb. 24, 2026 after local authorities confirmed they had received the federal and state documents. Officials said the documents will be examined alongside the original incident file from August 2025 as part of the continuing investigation into Dylan Harrison’s drowning during the certification session.

Investigators have not closed the matter; law enforcement and regulatory officials in the region continue to review the findings contained in the reports released Feb. 24, 2026. County and state investigators remain involved while federal reviewers have provided the supplemental details now being scrutinized in the August 2025 case file related to Dylan’s death at The Scuba Ranch.

As the probe continues beyond Feb. 24, 2026, authorities in and around Terrell say they will integrate the federal and state report details into their ongoing work. The new documents represent the most recent official step in an investigation that began after the August 2025 drowning of 12-year-old Dylan Harrison during an open-water scuba certification course.
