CUTLER BAY, Fla. – Miami-Dade police are investigating after a man and a woman were found dead in their Cutler Bay home.

Authorities said officers found a man and a woman dead Thursday night inside a home at 19311 Sterling Drive. Police said both appeared to have died from gunshot wounds.

Detective Argemis Colome confirmed Friday that the medical examiner's office and homicide detectives concluded that the deaths were the result of a double suicide.

Police said the 64-year-old woman shot herself. Her boyfriend, identified only as a 49-year-old man, found her, called 911 and then shot himself, authorities said.

The three-bedroom home is across from the Bel-Aire Elementary School.

"They're good neighbors," neighbor Laura Ault, said. "Always wave, say hi, very friendly. Get your mail when you're out of town. I'm all shaking. I'm just shaking, because it's a really nerve-wracking and scary situation. I really feel for their friends and family."

Authorities said the couple had been dating for more than 10 years.
