Florida Governor booed at vigil as hundreds mourn racist killings

There was a horrific scene in Florida on Saturday as a white man armed with a high-powered rifle and a handgun killed three black people at a Jacksonville dollar store, before shooting himself.

Local law enforcement are describing the shocking scene as a racially motivated crime.

Police say the killer had written several manifestos detailing his hatred for black people, and the senseless act of violence is now being investigated as a hate crime.
