Human tragedies such as the murder of seventeen people at the Marjory Stoneman Douglas High School in Parkland Florida bring out the best charitable impulses of many people, but unfortunately, they also bring out the worst impulses in scammers who use tragedies such as this to solicit contributions to phony charities and GoFundMe campaigns. The Broward County Sheriff has already warned people about a number of fraudulent GoFundMe accounts that have been set up to scam money from charitable donors. There is, however, an official GoFundMe account that is sponsored by the Broward Education Foundation which is legitimate. Here is a link to their account.

TIPS
In general when making charitable donations, in order to make sure that your charitable donations are going to where they can do the most good, make sure that any charity you wish to donate to is legitimate.  You can do this by going to http://www.charitynavigator.org and learn not just if the charity is a scam, but also how much of donations to the particular charity is spent on salaries and administrative expenses rather than going to the charitable purposes of the charity.  If you are contacted by phone, email or text message from a charity, you can never be sure that the person contacting you is legitimate even if he or she uses the name of a legitimate charity.  In that case, if you are charitably inclined, your best course of action is to contact the charity directly by phone or at an email address that you know is accurate to make your donation.
