SAN FRANCISCO — A first-grade student took a gun to his San Francisco elementary school Friday, the district's second such incident in two days, school officials and police said Monday.
Staffers at Cleveland Elementary School found the gun in the boy's backpack after overhearing children talking about a gun on campus, school officials said Monday. Police and the student's parents were then called to the Excelsior district school. It was unclear Monday whether the gun was loaded.
