WEST MIAMI-DADE, FLA. (WSVN) - Police took one person into custody after, they said, a domestic-related stabbing in West Miami-Dade left one person dead and sent another to the hospital.

Miami-Dade Police and Fire Rescue units responded to a home in the area of Southwest 16th Street and 72nd Court, just after 8:30 p.m., Saturday.

Surveillance video from a neighbor’s home captured the moment first responders arrived at the scene.

“I heard more cops and I looked down and there was a fire rescue,” said next-door neighbor Dunaikis Roche. “I peeked out of that window and I actually saw somebody being pulled out in a stretcher.”

Police said it was a family fight that escalated into what would be a deadly stabbing.

Area resident Phil Acosta said he heard shouting coming from the backyard minutes before police arrived.

“They were arguing in the back, then stuff started to escalate,” he said.

Authorities said one victim died inside the home, another has been transported to the hospital in unknown condition, and the apparent aggressor was detained.

“I’ve been living here for almost 10 years already. I’ve never seen nothing like this,” said Roche. “It’s very surprising, and to hear that, it’s shocking.”

Acosta said he’s known the couple that lives at the home for about five years.

He said their adult son had moved in with them recently.

“I guess their son had some kind of problem, and they try to help them out by letting him live there, but I guess it didn’t work out,” said Acosta. “They’d been arguing for days.”

Police have not yet identified those involved.

As detectives work the case, neighbors are trying to understand what went so wrong behind closed doors.

“They were great people, both of them. They would do anything for you,” said Acosta.

As of late Sunday night, police have not disclosed the surviving victim’s condition.
