A Brazilian lifestyle influencer died after she plunged from the balcony of her 10th-floor condo — and cops have arrested her husband while probing the fatal fall as a potential homicide.

Maria Katiane Gomes da Sliva, 25, who boasted nearly 6,500 followers on Instagram, was found dead outside her building in São Paulo, with her husband clutching her lifeless body and telling responding officers she had committed suicide after an argument on Nov. 29, according to local reports.

Her death was initially deemed suspicious and her seemingly grief-stricken spouse, 40-year-old Alex Leandro Bispo dos Santos, was cuffed 10 days later on Dec. 9 for femicide, O Globo reported.

Authorities obtained alarming surveillance footage from the day Silva died, showing Santos allegedly beating her in the parking garage, then arguing with her in the elevator — reaching for her neck at one point — before violently dragging her out.

Santos then returned to the elevator, where he collapsed with his head in his hands, the outlet reported.

Shortly after, startled neighbors called police after hearing screaming and a loud bang.

Police suspect Santos hurled Silva off their balcony and have him in temporary custody as the investigation continues, the outlet reported.

About a week before his arrest, Santos attended his wife’s Dec. 1 funeral, where he was seen kneeling beside her casket in tears, according to local reports.

Silva was born in Crateús, Brazil, where she later worked in a restaurant and supermarket before relocating to São Paulo, where she met and married her suspected killer husband, G1 reported.

The content creator — whose last social media post was on Nov. 8 — regularly shared videos about travel, makeup, health, and her daily routine, according to her Instagram.

Her final post showed her putting what appeared to be protein powder into a glass while dancing.

The investigation remains ongoing.
