The search for actress Naya Rivera has now shifted from a rescue to a recovery mission.
The former Glee star, 33, went missing in water with only 5 to 9 inches of visibility, and US authorities say the lake is filled with trees and debris on the bottom. Law enforcement says it typically takes 7 to 10 days for a body to rise to the surface.
Authorities are now saying they’re treating the case as a possible drowning.
More than 80 people are currently involved in the search, which is utilising helicopters, boats, all terrain vehicles and ground personnel.
Rivera had used the lake before and on this occasion rented a pontoon boat, but when she did not return it, rental staff at the lake found it at the north side of the body of water, with 4 year old Josey alone and sleeping aboard. He was wearing a life jacket.
The little boy told investigators that his mother did not get back in the boat after being in the lake.
“Investigators believe Rivera drowned in what appears to be a tragic accident,” an incident report reads.
Car park footage and a 911 call have also been released by authorities.
