WILSON COUNTY, Tenn. (WKRN) — The gunman accused of killing his estranged wife and his mother-in-law in a Lebanon subdivision Monday morning was later found dead in a vehicle near his Bellevue home, according to investigators.

Lebanon police had issued an alert around 8 a.m. and said the shooting suspect, identified as 36-year-old Shaun Varsos, was believed to be on foot in the Stonebridge subdivision off Leeville Pike. Residents were urged to “lock in place.”

Officers later learned Varsos, a man from Nashville, had fled in a gray Nissan Pathfinder with Florida plates headed toward Davidson County.

After a manhunt for Varsos, police said they found him dead inside of the SUV on the side of Harpeth Knoll Road in Bellevue. He died from an apparent self-inflicted gunshot wound, according to Metro police.

During a news conference around 10 a.m., Lebanon police spokesperson P.J. Hardy said Varsos was responsible for killing two women. Hardy said one of the women was able to fire back, striking Varsos.

The victims were later identified by police as Varsos’ 31-year-old estranged wife, Marie, and her 60-year-old mother, Deborah Sisco.

Officers said Marie Varsos had been living with her mother on Whispering Oaks Drive in Lebanon. Shaun Varsos broke into the residence around 8 a.m. and killed the two women, then drove to Bellevue, where he took his own life, according to police.

The Central Labor Council of Nashville and Middle Tennessee issued a statement Monday afternoon regarding the death of Deborah Sisco, the president of the CWA Local 3808:
