In a Facebook post, Morristown Police identified the suspected shooter in the incident early Saturday as 30-year-old Brandon Michael McMurtury.
Police say 30-year-old Angel Robert Garcia died from his wounds, while the 29-year-old resident of the apartment was taken to the hospital with injuries not expected to be life-threatening.
Detectives believe McMurtury forced his way into the apartment and shot the two others with a handgun before turning the gun on himself.
Police say the three knew each other and the resident told investigators she previously had problems with McMurtury.
An investigation is still ongoing.
