Car Causes StirLAS VEGAS, N.M. lt;AP) -Rio Arriba County deputies are using a patrol car purchased with federal grant funds until officials can decide what to do about the fact it isn’t the car for which the funds were meant.The Region Two Criminal Justice Commission this week voted to allow the use of the car until the grant manager, Tony Trujillo of Gov. Jerry Apodaca’s office, can determine its disposition or the proper procedure to obtain permission to use the vehicle as a patrol unit.Richard Serna of Santa Fe, the regional coordinator, said that in June 1975, two vehicles Were awarded from Law Enforcement Assistance Administration grant funds to the Rio yrlba County sheriff’s department.' He said the vehicles were to be unmarked police cars to be used by the area’s metro squad.But the day after delivery, officials discovered one of the cars was painted as a regular patrol car and was equipped with spotlights and emergency equipment, he said.Serna said this was in violation of the agreement because the vehicle was not intended to be used as a patrol car.The Rev. Robert Salazar, region two commission chairman, said he was concerned that the funds that were used by the sheriff’s office to change the car to a patrol car would havr to be given back to the LEAA.A sheriff’s department spokesman said the office thought the car was given to them and could be used as needed.He said the department already had three metro squad vehicles, and thought it would be all right to go ahead and paint one of the new cars for a regular patrol unit.
