Nikolas Cruz, the 19-year-old who charged with murdering 17 people at Marjory Stoneman Douglas High, honed his marksmanship skills in a school program supported by the NRA. Cruz was, according to the Associated Press, a member of the school’s four-person varsity marksmanship team, which received a $10,000 grant from the NRA in 2016.

The marksmanship team was part of the schools’ JROTC program. On the team, Cruz trained with “air rifles special-made for target shooting, typically on indoor ranges at targets the size of a coin.”

Cruz discussed his AR-15 with other team members and was given the nickname “Wolf.” Another member of the team described him as “a very good shot.”

The NRA declined to comment on the donation. The NRA foundation gave $2.2 million in similar grants promoting gun use to schools around the country

The NRA has been actively commenting on the Parkland massacre on social media, arguing that the only way to prevent future tragedies is more guns.
