Two Santa Maria High School students were investigated by police Thursday after both posted Snapchat photos -- one of a pistol replica and the other of an implied threat -- in the wake of Wednesday's mass shooting at a Florida high school. The first photo, reportedly posted on Snapchat by an unnamed freshman, made references to the Marjory Stoneman Douglas High School shooting Wednesday with a caption that read, "just wait until that same headline comes up on your mom's television one day, but it'll have Santa Maria High School instead, and well over 500 dead," followed by heart emojis.
