After you contact authorities, prepare a short written statement detailing the key points of what you observed. Give dates, approximate times, and locations. Timely fact-gathering is crucial—the more time that passes, the greater the risk that evidence will disappear, injuries will heal, or you'll forget specific details. Written statements from other witnesses will help back up your observations, and if possible, take pictures and date them—photos or videos will strengthen your case.

Always keep a dated record of everyone you've contacted, along with the content and outcome of your discussions. Never forward a letter, photograph, or other documentation to anyone without first making a copy for your own files. Make it clear to authorities that you wish to pursue the case and that you are willing to lend your assistance if necessary. Be sure to follow up! If you stay involved, authorities are more likely to do the same.

If the first contact doesn't produce results, go straight to a supervisor. If that doesn't work, appeal to local government officials, such as the mayor, the district attorney, or city council members. A call to the media in your area (television and print) can move mountains. Above all, don't give up—you may be an animal's only hope!
