There is once again a satellite office of the San Joaquin County District Attorney open in Manteca serving all of the South County including Tracy, Ripon, Lathrop and Escalon.District Attorney Tori Verber Salazar Thursday morning welcomed some 50 representatives of the law enforcement community into the front door of the new complex located at the Manteca Civic Center after a ribbon cutting ceremony in the walkway outside the front door.The modular office is housing DA staff that works with law enforcement and crime victims in the five South County cities as well as the CHP in the prosecution of cases. The move is designed to put prosecutors closer to officers to reduce costs and travel time which in turn increases officer time for patrols and other duties.She said it had been some six years since the former office on Center Street was closed due to the economic slowdown. It was also when the Tracy courthouse was closed.
