LOS ANGELES -- Authorities descended on the waters of Lake Piru just after sunrise Friday as the search for the body of actress Naya Rivera, who authorities say likely drowned while boating with her young son, stretches into a third day.
The 33-year-old was reported missing Wednesday afternoon after her 4-year-old son was found in a rental boat by himself. While authorities focused their initial search along the shoreline, hopeful she had made it out of the lake, Thursday became a recovery effort in the dark, murky waters of Lake Piru. Officials said the search of the lake could take up to a week.
"Our hearts and our prayers and thoughts go out to the Rivera family," Ventura County Sheriff's Sgt. Kevin Donoghue said at a Thursday news conference. "This is a terrible tragedy. ... We're going to do everything we can to find her."
Search teams raced to scour the lake Thursday before nightfall, when winds and lack of light would have complicated their undertaking. The search effort includes 100 personnel, including 25 divers, two helicopters and six pontoon boats, said Ventura County Deputy Chris Dyer.
Dyer said while Lake Piru isn't more dangerous than other lakes, the water can be deep in some areas and has tall underwater vegetation that could entangle swimmers.
"If the body is tangled in something beneath the water, it may never come back up," Donoghue said.
Rivera is best known for her role as Santana on Fox's "Glee." The Santa Clarita native gained praise for her performance as a gay cheerleader in the high school musical drama.
Video footage released by the Ventura County Sheriff's Office showed the actress and her son boarding the rental boat alone Wednesday afternoon.
Rivera parked near Condor Point and got out of her car, the video shows, walking around to the passenger side to lift her son out. Wearing shorts and a baseball cap, she opened her trunk, swung a bag over her shoulder and walked toward the boat ramp. Rivera looked over her shoulder, watching her little boy as he trailed steps behind her, his own bag in tow.
The mother and son were guided by staff to their rental boat, and about 1 p.m., they departed onto the lake. The pontoon boat soon became a spot on the lake's horizon.
