I need help nailing local authorities and mothers family

June 7,2004 my mother died of homicide covered by suicide.My mothers family is covering up death, her husband as well. My mothers husband was #1 deputy on scene. Purchased pictures from law enforcement, documents, toxicology reports as well. One lie and coverup right after another. Sherriff, deputy sherriff, deputy coronor, medical coronor as well as the pathologist are hiding and covering the truth. They all know as well as moms family that I know the truth and she was murdered and I wont quit til the truth is out. Pictures say 1000 words and deputies reports dont match up and all contradics with another. Someone tampered with evidence as well as her toxicology report. I need desperate help.
