Today, we’re taking a look at teens who kill, in particular teen mass shooters. Since teen assailants Eric Harris and Dylan Klebold killed their fellow Columbine High School students in 1999, these criminals have faced increased public attention.

According to the Violence Prevention Project at Hamline University, shooters between the ages of 11 and 19 have conducted 19 mass shootings in the US since 1966, killing 162 people and injuring 145.

This episode will address four of these shooters: Payton Gendron, Salvador Ramos, Colt Gray and Ethan Crumbley, and the devastation they have left behind.
