Actress and friend of Naya Rivera, Heather Morris has pleaded to join the search for the star.
The Glee star - who played Rivera's character's love interest on the long-running television series - has asked Ventura County Sheriff's Office if she can help the search for her friend, who is presumed dead.
The actress went missing on Wednesday afternoon. Her 4-year-old son Josey was found alone on a boat.
She wrote on Twitter: "My name is Heather Morris, I'm Naya's close friend and co-worker, and I'm trying to conduct an on foot search and rescue mission along with a small group of friends at Lake Piru. I understand your team is doing EVERYTHING in their power, but we are feeling helpless, powerless and want to help in any way. I have left a message with the department of Rescue and Air today, and I will call again tomorrow. Thank you."
