8-year old boy brings uncle's gun to school in California

A second-grade boy brought a gun to school in his backpack and showed it to friends, in Cathedral City, Calilfornia.  The gun belonged to his uncle, who was charged with child-endangerment and who also had another gun with the serial number removed.

From an article and news video:

On Thursday, school officials sent home a letter with children telling parents a second grade student had an unloaded gun in his backpack. 

A Palm Springs Unified School District security officials tells KMIR6 that guns and bullets and kids is a recipe for disaster. Offices say parents need to help to lock up the guns, make sure they're not available to the kids, and lock up the ammunition. 

Police arrested the boy's uncle, 24-year-old Ricardo Olivera, for child endangerment. Police say Olivera faces other charges as well for another gun they found in the home with the serial numbers removed. 

School officials were pleading with adults to make sure to lock up weapons, saying if a child hurts himself or somebody else with those weapons, whoever the owner of those weapons are, charges will be filed against them

Every gun in the hands of a child must first pass through the hands of an adult.
