Police say the 21-year-old Higgins was "very drunk" at a Bristol house party last month and was ridiculed because of flatulence. Police say one woman even slapped him because of it.
Police say at that point he stormed out of the party and returned about 45 minutes later with three knives and started stabbing people indiscriminately.
Matthew Walton died of his wounds. Three others were injured. Higgins told police he was angry and wanted to show that people shouldn't make fun of him.
