Police Sgt. Ryan Lindenbaum of the Sully District Station was just 30, in August 2015, when he died of a brain tumor. The following year, three of his high school friends – Alex Fetterman, Andrew Donahoe and Brian Beruete – established The Hercules Foundation in his honor. It raises money for college scholarships for law-enforcement families and helps them in times of need. Its primary fundraiser is an annual golf tournament, and this year’s event – held May 17 at the Pleasant Valley Golf Club in Chantilly – yielded $3,917.
