A man arrested in Richardson after he allegedly broke into a home and tried to carjack a nearby driver is also one of three people charged in the stabbing death of a 63-year-old man.
Jose Portillo was arrested Thursday after he allegedly forced his way into a woman's apartment at gunpoint. Police said the woman successfully fought him off. Minutes later, Portillo allegedly tried to carjack a man who took the gun away and called police.
"Once our victim took the gun away from him -- that gun was similar in make and model [to one] that we were looking for in our homicide," Richardson police spokesman Sgt. Kevin Perlich said.
The gun had been stolen from 63-year-old Jimmy Donawho's apartment. He was found stabbed to death in his home Sept. 7.
"We began to question him after he'd been taken into custody about the homicide, and he eventually confessed to the homicide and led us to identify two additional individuals that may have also had a role in that homicide," Perlich said.
Portillo, Omar Lima Lopez and Saul Montero Mata face capital murder charges in Donawho's slaying.
At the time of Portillo's arrest in Richardson, arrest warrants indicated that a Dallas police officer had tracked him to the Richardson area and suspected him in a sexual assault in the M Streets neighborhood.
However, Dallas police have not charged Portillo or confirmed if he is a suspect in the case.
Lopez, and Montero-Mata will all be held at the Dallas County jail. None of the men have legal immigration statuses, police said.
Police said they are working with the district attorney's office on all current and potential charges.
