A man and woman were shot dead in what police believe was a murder-suicide in Brooklyn early Friday, cops said.

The pair — a 52-year-old woman and a 45-year-old man — were discovered inside the living room on the second floor of the building on Menahan Street near Wilson Avenue in Bushwick around 8:15 a.m., according to police.

Their names were not immediately released, pending family notification.

The couple did not live at the home — but the woman was an aide to a bedridden 93-year-old woman who resided there, said another neighbor, Nieves Dominici, 86.

“She was a very nice person,” Dominici said in Spanish. “We exchanged a few words here and there. I heard three shots. They say he killed her first, then he shot himself.”

Raul Salas, a 60-year-old retired correction officer who lived nearby said he heard around three or four shots.

“Then everyone ran outside to see what happened,” he recalled. “The [93-year-old] lady was screaming and someone called 911.”

The elderly woman was unharmed, cops said.

Another neighbor who declined to give her name told The Post that the victim wanted to return to the Dominican Republic early Friday.

“It was jealousy,” the neighbor claimed. “She was going back to her country this morning, after her shift. He didn’t want her to go.”

Another neighbor, Julio Valentin, said he had just seen the woman on Thursday.

“She came out to take out the garbage [and said], “Hi Junior, how you doing?” Valentin said. “Then she went upstairs and I never saw her again. She was a nice lady. It’s crazy, I’m shocked.”

A gun was recovered on scene, cops said.
