Family members of Ryan Gabriel Rodriquez, who disappeared Friday while driving a water truck in rural Fresno County, offered a $20,000 reward for information about the missing man.
His father and mother, Gabriel and Cindy Rodriquez, pleaded for help at a Tuesday morning news conference called by the Fresno County Sheriff's Office.
Rodriquez, 32, was last seen around 10:30 a.m. Friday, driving a white water-tank truck in the area of Ford and Butte avenues near Huron, deputies said.
Rodriquez left a co-worker to go fill up the water truck, but never returned. His co-worker went looking for him and found his truck abandoned near a well where trucks get water. Rodriquez was nowhere to be found.
Cindy Rodriquez, Ryan's mother, pleaded for information about Ryan on her son's birthday.
"Thirty-two years ago, I gave birth to my only son Ryan," she said, with her voice breaking. "People love you Ryan, we want you back."
Sheriff's spokesman Chris Curtis said three detectives are working on the case and the sheriff's office has not ruled out foul play. He said that the search for Rodriquez was begun Friday afternoon by Rodriquez's family and friends and the California Highway Patrol plane also joined the effort Friday evening. The plane's crew was unable to find anything and the sheriff's helicopter crew also came up empty Saturday.
A Facebook page devoted to the search, Bring Ryan Home, had attracted nearly 3,000 followers by Tuesday evening. It included a mix of memories of the Firebaugh High School graduate, requests for help finding him and tips about possible sightings.
Friends and family have posted fliers in many communities asking for help.
Rodriquez is described as 5 feet 11 inches tall, about 170 pounds, with brown hair and brown eyes. He was last seen wearing white coveralls and boots.
Anyone with information is asked to call the sheriff's office at (559) 600-3111.
