Disturbing footage has emerged purportedly showing the moment a Florida sheriff’s deputy shot his ex-girlfriend and then himself during a violent argument.

The Palm Beach Post reported that the surveillance video allegedly depicting the October 12 crime was recently released by Boynton Beach police.

Police say the footage shows Michael DeMarco, in his uniform, threaten 40-year-old Yuly Solano with a firearm before shooting and severely injuring her and turning the gun on himself. He allegedly shot her once in the arm and twice in the chest, then fired the gun at his own head.

DeMarco, 55, died at the scene and Solano faced treatment for extensive injuries at an area hospital.

The video was released along with transcripts of investigators’ first interview with Solano at Delray Medical Center nearly a month after the shooting.

At one point in the interview, she said the detective told her she treated him “worse than a dog” during the altercation outside of her condominium complex just before he fired his weapon.

The mother of one had been walking her dog when her ex-boyfriend approached.

DeMarco and Solano had recently separated at her direction, according to authorities, “because he was being racist and very possessive of her.”

The Daily Mail interviewed Solano’s daughter, 18-year-old Aryana, who spoke on the victim’s behalf.

“She wants to get her message across because this could have been prevented,” the daughter said. “She could have been well right now. She wouldn’t have been in the hospital.”

The teen said she was at home at the time the shooting occurred outside.

“She was walking the dog so she normally doesn’t take too long, but she was taking longer than usual,” she said of her mother. “When I heard the shots I didn’t really think it could be mom, but then I heard the sirens and she still wasn’t coming back and I was calling her phone and she wasn’t picking up.”

Solano’s family is accepting donations toward her medical and living expenses with a campaign on GoFundMe.
