A northwest Houston man was clinging to life at the hospital Thursday, almost a week after authorities said his teenage girlfriend scalded him with boiling water.

Keira Jones, 17, was charged with aggravated assault after the June 18 attack on Ira Jones, 33, inside the home they shared in the 1000 block of E. 32nd Street.

According to the criminal complaint filed against her, the teen became angry because Ira Jones had been talking to another woman. She then threw a pot of boiling water at him..

His family declined to comment Thursday.

Neighbors said the couple had been together for at least two years — since she was 15. The complaint identifies her as the man's girlfriend.

"They acted like they really loved each other. But, they just couldn't get along," said Tony Spikes, whose son grew up with Ira Jones.

After the incident, Keira Jones allegedly fled — later taking her clothing and personal belongings from the house.

After he was doused with the boiling water, Ira Jones then called his father

His father took him to his own home then called police. Ira Jones was rushed to Memorial Hermann Hospital's burn unit. Doctors there said he had second-degree burns over 15 percent of his body and other medical problems, including renal failure, according to the criminal complaint.

Ira Jones is on life support and is not expected to survive, police said in the complaint.

On Tuesday, an aggravated assault of a family member charge was filed against Keira Jones.

"It was difficult to get a statement from (Ira Jones) given the condition he was in. It took a couple of days to find out exactly what happened," said Victor Senties, a Houston police spokesman.

HPD patrol officers arrested Keira Jones on Wednesday after they saw her walking along the 8000 block of Lawn.

On what appears to be her Facebook page, Keira Jones traces the relationship with her much-older boyfriend.

On April 23, she posted being at home with her "husband," whom she identified as Ira Jones, Jr.

She continues along that vein for several days on Facebook, saying "He brings so much joy to me."

Her Facebook postings become darker within a few days. On May 2, Keira Jones wrote that she was "letting (him) go" and "can do better" without him.

In later expletive-filled Facebook postings, Keira Jones condemned people who "claim they love you but when you need them they (are) never there."

On June 19, the day after police said Keira Jones threw the boiling water, her Facebook status suddenly changed to "single."

On the day Harris County prosecutors filed the aggravated assault charge against her, Keira Jones posted her latest comment on Facebook.

"You shouldn't have hurt me the way you did and (you) wouldn't have (gotten) the reaction I gave you," she wrote.

Keira Jones is being held without bail at the Harris County Jail.
