Jennifer was then promoted again to the Grand Jury warrant rotation where she presented numerous cases to the Grand Jury and secured indictments in nearly every case. In addition, during that time, Jennifer assisted police officers and detectives in determining what crimes to charge defendants with and advised them on how to handle certain legal situations. Jennifer also handled all requests by detectives and police officers for search warrants in matters including homicides and vehicular manslaughter.
