One vacation stop for a newly-engaged couple turned to tragedy last week following an accident at Olympic National Park.

Officials announced the presumed death of 37-year-old Travis Valenti on Tuesday, citing a kayaking mishap on Lake Crescent. According to the statement, the incident occurred the afternoon of June 9 when Valenti and his fiancée, to whom he proposed just two days prior, ventured out into the chilled waters.

Valenti’s kayak began taking on water during the trip, eventually forcing him to abandon the vessel when he could no longer paddle. His fiancée, Marlene, attempted to help but also ultimately ended up in the water after her kayak overturned. While Marlene was able to swim to shore in the cold water -– around 50 degrees Fahrenheit on the surface around this time of year, according to the National Parks Service (NPS) – Valenti was unable to follow suit.

Though staff from the nearby Log Cabin Resort quickly responded by taking boats out onto the lake to search for Valenti, he could not be found near his last known location. Park rangers and the local fire department joined the search shortly after, spending more than two hours investigating the area roughly a quarter mile from the shore and combing the waters again the following morning.

Valenti has yet to be located.

The search continues

The couple, originally hailing from Massapequa, NY, were on vacation in Washington at the time of the accident, according to a Facebook post made by Valenti’s cousin.

The pair had just gotten engaged the Wednesday before the Friday accident and were “exciting to begin their lives together.” Valenti’s brother, Austin, told local station News 12 Long Island that Travis succumbed to drowning only after giving his fiancée the “push” that allowed her to return to shore safely, an act that he credits with saving her life.
