I'm trying to classify this dude. Thought he might have fallen into the spree killer category, but due to the single location, it seems he does not qualify in this category:
"A spree killer is someone who kills two or more victims in a short time in multiple locations. The U.S. Bureau of Justice Statistics defines a spree killing as "killings at two or more locations with almost no time break between murders".[1]"

Eta / Reposting / Serial Killer:
"A serial killer is typically a person who murders three or more people,[1] usually in service of abnormal psychological gratification, with the murders taking place over more than a month and including a significant break (a "cooling off period") between them.[1][2] Different authorities apply different criteria when designating serial killers;[3] while most set a threshold of three murders,[1] others extend it to four or lessen it to two.[3] TheFederal Bureau of Investigation (FBI), for example, defines serial killing as "a series of two or more murders, committed as separate events, usually, but not always, by one offender acting alone".[2][4]
Although psychological gratification is the usual motive for serial killing, and most serial killings involve sexual contact with the victim,[5] the FBI states that the motives of serial killers can include anger, thrillseeking, financial gain, and attention seeking.[4] The murders may be attempted or completed in a similar fashion, and the victims may have something in common: age group, appearance, gender, or race, for example.[6]"

Rampage Killer is an umbrella term for spree killers.

Mass Murder:
"Mass murder (sometimes interchangeable with "mass destruction") is the act of murdering a number of people, typically simultaneously or over a relatively short period of time and in close geographic proximity.[1][2] The FBI defines mass murder as murdering four or more persons during an event with no "cooling-off period" between the murders. A mass murder typically occurs in a single location where one or more people kill several others.[3][4] Many acts of mass murder end with the perpetrator(s) dying by suicide or suicide by cop.[5]
A mass murder may be committed by individuals or organizations whereas a spree killing is committed by one or two individuals. Mass murderers differ from spree killers, who kill at two or more locations with almost no time break between murders and are not defined by the number of victims, and serial killers, who may kill people over long periods of time. Mass murder is the hypernym of genocide, which requires additional criteria."
