Ira Jones Jr., also known as 'Tick,' had been on life-support since June 25. That's when police say his live-in girlfriend -- Keira Jones, 17 -- attacked him in their northwest Houston home.
According to court documents, she became angry with him because he had been speaking with another woman. At some point, investigators say she threw a pot of boiling water on him.
Jones Jr. was taken to Memorial Hermann Hospital's burn unit with second degree burns on 15 percent of his body.
Keira Jones was arrested Wednesday and charged with aggravated assault of a family member. She is now being held in the Harris County Jail without bond.
She was to have a bond setting court appearance Friday, but it was postponed until August.
With her boyfriend's death, the charge could be changed to murder. However, the Harris County District Attorney's Office says the aggravated assault charge may remain.
Prosecutors say it's a first degree felony and, if she is convicted, it would carry the same punishment as a murder charge.
The family of Keira Jones says the two met when she was 15 and the victim was 30.
The defendant's mother, Karen Jones, says she never approved of the relationship and tried to get Jones Jr. to leave her daughter. She says she has never known her daughter to be violent.
