Today, a California high school student used a .45 caliber semiautomatic handgun to shoot up his school.
He killed two and wounded three others before turning the gun and gravely injuring himself.
Reuters reports it was his 16th birthday.
Police said the shooter acted alone and descended on his family home, blocking off the street.
There was no immediate word on where the teen gunman obtained the weapon.
This is at least the 85th incident of gunfire on school grounds this year.
This year marks the 20th anniversary of the shooting at Columbine High School as well.
