A pistol was recovered from the stolen car, the sheriff said.
“We’re very relieved this morning,” Gonzalez said about Rodriguez’s capture.

The sheriff said his agency had deputies positioned in the Cypress area before the suspect was spotted because the first crime attributed to Rodriguez, a July 9 home invasion and robbery, took place less than half a mile from where he was ultimately captured.
Rodriguez’s parents also live in the area and he grew up there, the sheriff confirmed.
The first homicide that Rodriguez is suspected of committing also took place in Cypress. Pamela Johnson, 62, was found shot to death in her home there Friday evening.
Gonzalez said during a news conference over the weekend that Johnson's family became worried when no one could get in touch with her. The last time family members spoke to Johnson was around noon on July 10, the day after the home invasion about two and a half miles away.
Detectives investigating Johnson’s slaying found that personal property was stolen, including Johnson’s maroon 2004 Chrysler PT Cruiser, the sheriff said. The PT Cruiser was found Saturday evening at Willowbrook Mall after a citizen reported seeing the vehicle aedbandoned in the parking lot.
Mall surveillance video footage showed a man -- later identified by investigators as Rodriguez -- park the vehicle around 11 a.m. that morning. The man was seen on video walking through the mall and exiting the building on the opposite side from where he abandoned the victim’s car.
Around 7 p.m. that same night, the body of Mattress Firm manager Allie Barrow, 28, was found by a fellow employee, stuffed between two mattresses in the back of the store. The Mattress Firm store where Barrow was slain is in a strip mall across the street from Willowbrook Mall.
Barrow had been shot in the head, investigators said.
Gonzalez and Houston police Chief Art Acevedo, who held a joint news conference Monday afternoon to identify Rodriguez as a person of “strong interest” and ask for the public’s help in tracking him down, reported that a third homicide took place that morning at a Mattress One store in Houston, where a man was found shot to death.
The Nissan Rodriguez was driving when captured was taken from the scene of the Mattress One homicide, officials said. KPRC in Houston identified the victim of that killing as Edward Magana, 57.
A fourth person, a 22-year-old Metro Lift driver, was also shot in the abdomen and robbed Monday morning in Houston. Acevedo said that the bus driver was expected to survive.
The motive for the crimes was not known, Gonzalez said Tuesday morning. Neither he nor Acevedo detailed how Rodriguez was tied to all the crimes.
Rodriguez was released from prison in September, the Chronicle reported. Texas Department of Criminal Justice spokesman Jeremy Desel told the newspaper that his release was mandated by law, due to the amount of time he'd already served.
Rodriguez, whose violent criminal history dates back to at least 1989, was on parole and was supposed to be on supervised release until 2023. He was ordered to wear an ankle monitor, but the Chronicle reported that he had tampered with it in the days before police and sheriff's deputies began searching for him in connection with the homicides.
It was unclear if he was still wearing the disabled device when he was arrested.
Records accessed by the Chronicle showed that Rodriguez was sent to prison for attempted sex abuse, burglary and auto theft charges in 1989. Then 17, he was sentenced to 25 years in prison.
While in prison, he was charged in a theft case out of Montgomery County, for which he was sentenced to 10 years, with that time to run concurrently with his sentence on the previous charges.
Rodriguez was also found with a weapon while serving time, the Chronicle reported. Another 10 years was added to his sentence.
He served 28 years in prison before his release on parole last fall. Texas' sex offender registry shows that Rodriguez was classified as high risk.
