He then filmed her apparently fighting for breath at her home in São Paulo, Brazil.
The couple had been in a troubled relationship for about a year.
In the days leading up to the incident, Cassiane left the house with her youngest daughter, four, after telling her relatives that Rodrigo had been threatening her.
In one message, the victim said: “When I get home, he said everything will be broken.
“He said he’s going to kill me today.”
Rodrigo allegedly sent a video of him threatening Cassiane with a knife to her sister the day before her death, as reported by Need To Know.
On the day of the crime, she returned to the property to collect some belongings and found the suspect waiting for her.
He then sent a video of the victim in agony to her relatives.
He claimed she had attempted suicide.
He said in the clip: “Look what she’s spitting out there.
“That’s the coffee and acid she drank, you understand?”
The emergency services arrived on the scene and found Cassiane with burns from her tongue to her oesophagus, consistent with forced ingestion of a corrosive substance.
A bottle of caustic soda with a warning label was found at the scene along with a knife left under the bed.
The police have already ruled out suicide after analysing the scene and taking statements.
They are currently investigating the case as qualified homicide and torture.
The victim leaves behind three children.
Rodrigo disappeared after the alleged murder and currently remains on the run.
He has been formally declared a fugitive as the investigation continues.
