BRISTOL, Tenn. — A man killed his ex-girlfriend's current boyfriend, her mother and two other people, then killed himself after police caught up with him in a rural area, authorities said.
Rusty L. Rumley came to the family's apartment in a public housing complex Wednesday morning under the ruse of needing help moving furniture, Bristol police Chief Blaine Wade said.
Rumley, 26, took Francis Watson — his ex-girlfriend's 43-year-old mother — and her neighbor Roy Malone to a breezeway outside the 10-story Edgemont Towers where he shot them, police said.
Then he returned to the family's eighth-floor apartment and asked his former girlfriend for a drink. As she got it, he fatally shot her boyfriend, Brandon Michael Roskos, 20, and another friend, 53-year-old Danny Wayne Murray, Wade said.
