On Tuesday, the family issued a desperate plea for their son's return and offered a $20,000 reward. On Wednesday, the Fresno County Sheriff's Office said the reward for any information leading to Rodriquez's return has been raised to $100,000.
Ryan's family said he was in good spirits when he showed up for work Friday and it was a normal day, until he vanished around 10:30 a.m. while filling up a water truck near Huron.
Fresno County Sheriff's investigators have scoured the westside of Fresno County, using search dogs and a helicopter. A CHP airplane also flew the area using infrared heat sensors. But, so far they have turned up few clues as to where Ryan could be.
Ryan's family says they know of no life circumstance that would make him leave and it's not like him to ever lose contact with them. A co-worker, who spent early Friday with Ryan, did not report anything unusual.
Investigators have also been monitoring any financial activity, including Ryan's ATM card, but there have not been any transactions since he disappeared.
