MARIETTA, Ga. -- Cobb County police are investigating a triple shooting inside an apartment.

It happened at around 2:30 p.m. Sunday at the Ivy Ridge Apartments off Bentley Road.

Monday afternoon, police confirmed the shooting was a double murder-suicide. Cobb County Police Sgt. Dana Pierce said the shooter was 45-year-old Pericles Demoura. The other two victims were identified as 35-year-old Thelma Vinhal and 30-year-old Euclides Guinato-Bernardes.

Investigators confirmed Demoura once dated Vinhal, and that Guinato-Bernardes was her new boyfriend.

Pierce said the whole incident was contained within one apartment.

"Everything was contained here inside the apartment. Initially there was speculation that people were missing from this immediate scene. That was not the case," Pierce said.

Neighbors said the victims are part of a close-knit Brazilian community in the area.
