On Monday, the National Transportation Safe Board (NTSB) issued a statement on their website announcing that the wreckage from the plane crash on Sept. 4 that killed 10 people – including Hilty's pregnant sister, Lauren, her brother-in-law, Ross, and her nephew, Remy had been found.

"Due to the depth of the water (approximately 190 feet) and the current (3-5 knots), the most suitable tool for recovery is a work class remotely operated vehicle (ROV)," the statement on the NTSB website read. "NTSB continues to be in communication with federal agencies and local companies to obtain a work class ROV."

Hilty spoke out about the tragic incident over Labor Day weekend via her Instagram on Sept. 8.

"My beloved sister Lauren, brother-in-law Ross and baby nephew Remy were on that plane," the actress wrote. "To make this news even more devastating, my sister was eight months pregnant and we were expecting to welcome baby boy Luca into the world next month. 

"It is important these details be corrected to respectfully honor everyone we’ve lost and the loved ones they’ve left behind," Hilty continued.

The float plane crash happened near Whidbey Island in Puget Sound, halfway between its destination and takeoff points. The crashed aircraft was identified as a single-engine de Havilland DHC-3 Otter propeller plane, according to the NTSB. 

The plane was operated by Friday Harbor Seaplanes, an organization that says it is "heartbroken" by the crash.
