CROWN POINT â The Lake County Council will not jump the gun and establish a purchasing agent for the sheriff's department until its legal dispute with the Lake County Commissioners over control of county government purchasing is resolved. Sheriff Oscar Martinez Jr. asked the seven-member council to speed up its takeover of county purchasing because he said the continuing refusal by the three commissioners to consent to all his purchase requests is endangering officer and public safety in Lake County. Martinez specifically cited his department's need for "blue light" technology used to detect blood and other bodily fluids at crime scenes, vehicle antennas that connect to satellite internet service, and a new boat for Lake Michigan water rescues.
