Hawaii County police are investigating a possible drowning of a 62-year-old woman who was visiting from Portland, Ore., when she died Wednesday night while participating in a guided manta ray snorkel trip.
Hawaii island police said in a news release that at around 9:28 p.m. Wednesday, Kona patrol officers and Hawaii Fire Department personnel responded to the Keauhou Pier to a report of a possible drowning.
Officials said Lori Trende-Landgraver was participating in a guided manta ray snorkel trip and went into the water after a safety briefing.
Five minutes later, police said she returned to the boat complaining of soreness to her arms. When she re-boarded the boat, Trende-Landgraver told the captain that she wasn’t feeling well and shortly after became unresponsive.
Crew members conducted CPR on Trende-Landgraver and HFD medics met the boat at Keauhou Harbor when it returned.
Police said medics continued medical treatment and transported Trende-Landgraver to Kona Community Hospital where she was pronounced dead shortly after being admitted.
