Video shows the moment the owner of a Brooklyn laundromat was shot dead during a robbery last week — leaving him lying on the ground in a pool of blood.

Money Perkins, 37, was cleaning the top of a washing machine at Money P Clean in Flatbush around 5:50 p.m. on Dec. 1 when three men in puffer jackets stormed in and drew guns on him, according to surveillance footage obtained by The Post.

Perkins can be seen lunging at one of the men, wrestling him to the ground and struggling with him briefly as the other two armed robbers stand by.

Moments later, a fourth attacker opens the door and shoots the laundromat owner — as a gunman standing near Perkins’ head also appears to blast the victim, the video shows.

It’s unclear which member of the violent crew shot first.

Perkins — no longer struggling — lays in a pool of his blood as the man he grappled with on the ground grabs at his neck, according to the clip.

The three others head out the door while the man smashes Perkins’ head into the laundromat’s floor multiple times, the stomach-churning footage shows. 

He then snatches Perkins’ chain from his neck before leaving the grisly scene, according to the video.

EMS rushed Perkins to Kings County Hospital, but he could not be saved, police said. 

The attackers targeted Perkins because of his chain, police sources told The Post. 

It’s unclear how they knew he would be at the business, located at 4710 Clarendon Road, at the time.

The suspects were still in the wind Wednesday.
