Lexington Police are now investigating a shooting Friday night as a murder-suicide.

The Fayette County Coroner has identified 44-year-old Keith Plaster and 32-year-old Tiffany Duiguid as the two people who died in that shooting.

Neighbors ABC 36 spoke to Saturday say they are shocked, they did not see any warning signs. According to police, it appears the two were arguing when Plaster shot Duiguid.
