Lloyd Cearley, 43, found dead in Sacramento River

Sacramento County authorities confirmed Monday the death of a 43-year-old Mammoth Lakes man, whose body was found in the Sacramento River on Saturday.

Details as to the cause of death of Lloyd Cearley were withheld as of Monday morning, pending notification of his father, according to a Sacramento County coronor's office spokeswoman.

Cearley, who was suffering from thyroid cancer at the time of his death, was in Sacramento County to see a doctor, according to a Facebook post from his sister, Nicole Cearley Van Alstine.

Cearley disappeared on Thursday, but his truck was found in a dirt parking lot near the Sacramento River on Friday.

Cearley, an events producer who last June produced the Mammoth-to-Bishop Bike Ride to raise funds for his fight against cancer, also worked as a seasonal bartender.

Cearley's sister wrote that he was last seen around 9:30 p.m. on Tuesday, Aug. 13, at a friend's home in Sacramento.

He was staying with his friend to be closer to his radiation appointment scheduled for 1 p.m. on Wednesday, Aug. 14th.

When his friend awoke the next morning, Cearley was gone, along with his truck and his wallet, but he left his cell phone, medication, and all other personal belongings behind.
