A glamorous Brazilian businesswoman was gunned down by her paranoid, much-older boyfriend just after she dumped him in a phone call, according to a report. 

Priscila Lacerda Custodio, 24, had only been dating cattle rancher João Roberto Bolelli, 62, for four months — but complained he’d hired people to watch her while also threatening to kill her, an unidentified friend told Globo.

He also scared her by the way he quizzed her about trips she took, accusing her of cheating on him — and also allegedly assaulted her just four days before the murder Friday.

Custodio, who worked in digital marketing, was so scared of her much-older lover she made her brother and a friend join her as she went to Bolelli’s São Paulo ranch on Friday to return a pickup she’d been using.

But they started arguing during a phone call before she even got there, with the glamorous 24-year-old saying she’d finally had enough and was ending their short-lived romance, the outlet said.

Bolelli allegedly opened fire when his lover arrived, killing her with shots to the chest and arm.

Bolelli — who was previously banned from seeing a different ex years earlier — then aimed the gun at his slain ex’s brother, chasing him before fleeing the scene. An arrest warrant has been issued for what is being treated as femicide.

Custodio was a “wonderful person” whose life “was cut short by an evil man,” one friend, Juliana Amaral, told Globo.

“She was beautiful, charming, and extremely polite,” Amaral said. “In three years of friendship, I never saw her speak badly of anyone.”

Bolelli was previously convicted for breaching protective orders obtained by another former partner. He was sentenced to three months and 15 days in prison in December 2021.

A legal representative said the case was being reviewed but that the suspect had not been in touch.
