Rodrigues handed herself into police in the city of Manaus on March 8, three days after she allegedly shot the businessman at the back of the head with a 380 calibre pistol.
Paulo Roberto was then rushed to the hospital, but died on March 7.
Speaking with reporters, the victim’s brother, Rodrigo said the suspect killed Roberto because he refused to pay for her silicone breast implants, which can cost around £1,300 ($1,800) in Brazil.
“He gave her a car, a job, money. She wanted silicone, but in times of pandemic, the company was cutting costs and he could not give her this surgery.
“They fought a lot because of this on the night she took my brother’s life,” He told local media.
The victim’s sister, Roberta, told local media her brother employed the ex-girlfriend at his company and they had a year-and-a-half-long relationship.
“From what we saw, she was just with him out of self-interest. She liked to show off, but she never posted anything about him.
“It seems he discovered something serious about her and they broke up,” she said.
Roberta said the suspect went to the victim’s house and said she wanted to speak to him. Hours later, his family was told he had been shot.
“She still had access. Before arriving, she switched off the house’s cameras.
“She premeditated everything. When she fired the shot, she walked out and called her mother to tell her.
“Her mother told my brother and the two of them went there. My brother arrived and saw him dying in the kitchen.”
Rodrigues fled after the shooting, but handed herself in to police accompanied by lawyers after an arrest warrant was issued for her.
She appeared with a lawyer at the Specialized Homicide Police and Kidnappings (DEHS) on Monday, but was arrested after she claimed the shooting was accidental.
Chief Marilia Campello, deputy of DEHS, said: “Cristina confessed to the crime, but claimed she had no intention of killing Paulo Roberto. She said the businessman had two firearms, one in the house and the other in the car.”
KanyiDaily had also reported how a 20-year-old girl was rescued while attempting suicide after discovering that her boyfriend for whom she was pregnant, was already married with kids.
