Keep good records
Write down all warning signs you observe. Try to include the dates, times, locations, and details of any incidents, the names of any people who observed the incident, and any photographs or other proof of what you observed. You can give this information to the authorities when you file a report.
Keep a record of all communications such as phone calls, meetings, letters, and emails. List the names and contact information for anyone you speak to about your concerns.
Talk to staff members and volunteers who may have observed something. Be sure that they also
document each incident in their records.
