The Waller County District Attorney’s Office is proud to have asked for and received help from State Representative Cecil Bell in sponsoring a bill during the 2015 Legislative Session that allows district attorneys to retain reserve investigators to assist with the duties of the office.  This new law will allow retired officers and officers which may be pursuing employment in the private sector to serve as reserve peace officers for the D.A., and to conduct investigations and enforce laws in the county.
