A Lafayette family is holding out hope that their loved one will be found after going missing while tubing down the Sacramento River over the holiday weekend.



Brett Michael Olson is a student at Cal Poly-San Luis Obispo. He was last seen about 1 p.m. Sunday when he arrived at Beer Can Beach near Chico for a float down the river with a group of friends.



Olson was in Chico for the holiday weekend visiting Chico State friends.



Olson's parents handed out hundreds of fliers Tuesday. They were joined by more family and friends on Wednesday as they waited for word as search crews looked for Olson further down the river.



A Facebook page "Let's Bring Brett home", had more than 30,000 members by Wednesday afternoon.
