Are mass murderers supplanting serial killers? Improved forensic science such as DNA has allowed law enforcement to arrest budding serial killers before they can rack up three or more murders.
But, with the explosion of gun sales, spree killers are running rampant in America.
Just this past weekend alone in South Florida, Boca Raton Police responded to a fatal shooting that occurred at the Dixie Manor Apartments on Sunday afternoon.
When officers arrived they found two gunshot victims. One man was declared dead at the scene while the other was transported to Delray Medical Center for non-life threatening injuries. The suspect fled the scene in a gray older model vehicle.
And three people are dead and six more are hurt after a mass shooting late Saturday night outside Miami. Police say it happened after a graduation party in a Kendall strip mall hookah lounge. Two men and a woman, who was a Florida corrections officers are dead, while three other men and three women were hurt when gunfire erupted as people left the graduation party. Six others were wounded and are reportedly in stable condition.
