Police arrested Raymond John Garcia, 24; Ernesto Guadalupe Ruiz Esparza, 19; and Ralph Anthony Garcia, 21 — all San Jose residents.They were arrested on April 23, 25 and 29 respectively, according to officer Garcia. He did not know specifically why police waited to announce the information until Thursday.The arrests stem from the death of Enrique Flores on April 17, as he walked from his house about 10 p.m. to a market near Almaden Expressway and Foxworthy Avenue. His girlfriend, Nancy Nieto, said he went out to buy beer, and chips for their daughter, who is a kindergartner at Schallenberger Elementary School. He never came home.According to police, Flores had no known relation to the suspects. Police had originally said the killing was not gang-related, but Thursday, Garcia said the motive does appear to be gang-related."I think he was there at the wrong time," Nieto said. "It makes me feel much better that they've been arrested."According to Nieto, Flores came to the United States from Mexico when he was 21, and was a mover for Graebel Relocation Services. She said he was the family's sole provider. The two had been together for seven years.
