A keen observation by a Modesto police officer led to the arrest of three suspected burglars early Tuesday. Officer Jesse Gutierrez was looking for stolen cars in the area of Tully Road and Del Monte Avenue when he saw three men wearing gloves and backpacks looking over fences and into residents' yards, said Lt. Scott Blom. Gutierrez stopped the three men and discovered they were carrying stolen property from two recent vehicle burglaries. They also were carrying shaved keys and porcelain chips, which are used to break into vehicles, Blom said. Jeremy Prather, 29, Nicholas Downs, 27, and Pedro Hernandez, 22, all of Modesto, were arrested on suspicion of vehicle burglary and receiving stolen property. "It was a great observation by the officer," Blom said. "He took down three burglars." Gutierrez was in the neighborhood just south of West Roseburg Avenue, where there has been a rash of stolen cars, Blom said.
