Family and friends of Murillo are anxious and on Saturday moved their efforts into the water.
"We've be out on land passing out flyers, hitting every establishment that's around here in this pier area and now we're going to go in the water," said Ronnie De La Mancha, Murillo's uncle.
Late Saturday, six people rented kayaks to search the bay. They circled Pier 30-32, checking between pillars and rocks, while another group rented a boat and scanned the water from Angel Island to AT&T Park.
"It sounds like most promising place is around here where incident happened," said Heather Cropley, a friend.
But four hours into their search, they found nothing. The lack of any signs is taking its toll.
"Victor was important person to me and it just feels better for me to be out here doing something rather than sit around," said Cropley.
The 27-year-old man vanished after the Giants-Dodgers game. He was last seen on the pier when he suddenly disappeared. It is believed he fell into the water and he doesn't know how to swim.
"Even if a strong swimmer were to have fallen in that water, it would be quite some time to get themselves out, in conjunction with the temperature of the water being so cold, I mean, who knows what the actual situation was at that time," said Lyndsay Carlock, a friend.
Volunteers are posting fliers all along the Embarcadero and Crissy Field and are asking the public for help.
The US Coast Guard officially called off their search Tuesday, but volunteer searches will continue Sunday morning.
