Homicide detectives arrested Isaac Vaughn, 33, of Riverbank as he left a Walmart at 2480 Geer Road in Turlock. An anonymous caller who had seen Vaughn’s photo from CrimeStoppers wanted posters recognized him and called authorities.

Detectives were able to respond to the location and arrested Vaughn, without incident, as he exited the store.

Deputies had identified Vaughn as a suspect in the murder of Jesus Quintana, who was found dead and partially clothed in the front yard of a house in the 3700 block of Texas Avenue in Riverbank on Tuesday night, Aug. 5.

Investigators determined Quintana died during a fight with Vaughn.

After an autopsy later that day concluded the case was a homicide, detectives issued a warrant to arrest Vaughn on a charge of murder.
