Hawai‘i Island police are investigating a possible drowning involving 62-year-old Lori Trende-Landgraver of Portland, Oregon.
On April 30, Kona patrol officers and Hawai‘i County Fire Department (HFD) personnel responded to the Keauhou Pier for a report of a possible drowning. In the course of their investigation, officers learned that Trende-Landgraver was participating in a guided manta ray snorkel trip. Following a safety brief, she was in the water for approximately five minutes before returning to the boat complaining of soreness to her arms. After she re-boarded the boat, Trende-Landgraver related to the captain that she wasn’t feeling well and shortly thereafter became unresponsive. Crew members initiated CPR and the boat returned to Keauhou Harbor where it was met by HFD medics.
Trende-Landgraver was then transported to Kona Community Hospital where she was pronounced deceased.
Police have initiated a coroner’s inquest investigation to determine the exact cause of death. No foul play is suspected.
Police are asking anyone with any information regarding this incident to contact Kona Patrol Officer Lawrence Matsumoto (808) 935-3311 or via e-mail at lawrence.matsumoto@hawaiicounty.gov.
