Vincent Martin gave his grandson two $20 bills for work he had done around the house and drove him to a bus stop on Valley Boulevard near Lincoln Park. It was the last time he saw him.
But Romero said he and Scott never met that day. He expressed confusion about the swap meet story because he and Scott had never planned such an outing.
"He told me he was going home to get some money and that he would be back Friday night because there was a party at a hotel in Rosemead," Romero said. "That's the last I heard from him."
Ray Martin said his son was street-wise enough not to run into trouble by accident. He thinks Scott was taken by force to the concrete wash by people he knew.
"I saw the splatter of blood on the concrete wall. I wanted to know exactly what my son went through," he said. "The thing that eats at me is that he died alone and I wasn't there to help.
"If I had known and I was within a distance to be there, I would have been there. And they would have had to kill two Martins that day."
