Barry Lee Grunow was a 35-year-old English teacher at Lake Worth Middle School in Lake Worth, Florida, who was fatally shot on May 26, 2000. The shooting occurred on the last day of the school year when a 13-year-old student, Nathaniel Brazill, returned to school after being sent home earlier that day for throwing a water balloon. Brazill brought a .25-caliber handgun he had taken from a family friend, confronted Grunow in his classroom after being denied permission to speak with friends, and shot him in the face.

Brazill was arrested and charged with second-degree murder and aggravated assault. A jury convicted him of those charges but did not find him guilty of first-degree murder; he was sentenced to 28 years in prison and seven years of probation. The shooting prompted several civil suits: Pam Grunow, Barry’s widow, sued the handgun owner, the Palm Beach County School Board, and the pawn shop that sold the gun, with settlements exceeding $1 million; she also obtained a $1.2 million jury verdict against the gun manufacturer that was later set aside on appeal. The Lake Worth community later named the school gymnasium for Grunow and established a scholarship fund in his honor.
