ANGLETON, Texas – Brazoria County prosecutors are seeking the death penalty against the Porter mother accused of shooting her four children last year, killing two of them and critically injuring two others.
According to a court document obtained by KPRC 2 Thursday, prosecutors intend to seek the death penalty against Oninda Romelus, 31, who is charged with capital murder and aggravated assault in connection with the Oct. 4, 2025, shooting.

The filing states prosecutors intend to prove aggravating factors that would warrant a death sentence, including allegations that Romelus would pose a continuing threat to society if allowed to live.
The development comes months after a Brazoria County grand jury indicted Romelus on charges related to the shooting.
According to investigators, Romelus called 911 shortly after pulling into a gas station at FM 521 and Highway 288 in Angleton.
When deputies arrived, they found all four of her children suffering from gunshot wounds inside the vehicle.
A 13-year-old boy and a 3-year-old girl were pronounced dead at the scene. An 8-year-old boy and a 9-year-old girl were flown to a Houston hospital and survived their injuries.
Previous court records obtained by KPRC 2 revealed Romelus allegedly made disturbing statements to investigators after her arrest.
Documents state she initially told investigators she “couldn’t talk about it,” before later saying, “Instead of them doing it to me, I’m gonna do it to them.”
When investigators asked what she meant, records show she responded, “Kill them all.”
Search warrants executed at Romelus’ Porter home also revealed investigators seized dozens of Social Security cards, identification cards and credit cards belonging to other individuals, along with computers, phones, printers and other devices investigators believed may have been used to create fraudulent identification documents.
The death penalty notice marks a significant escalation in the case and means prosecutors will now pursue the most severe punishment available under Texas law if Romelus is convicted.
The filing comes as defense attorneys continue preparing for trial.
Recent court filings show the defense has requested access to grand jury testimony, sought expanded juror questionnaires and asked for additional pretrial motions as the capital murder case moves forward.
Romelus remains in jail in Brazoria County on a $14 million bond.
KPRC 2 contacted Romelus’ legal representation for a statement on the new developments. Her attorney, Mike Diaz, said he is unable to speak due to an active gag order in the case.
