Raul Meza told police he was having a sexual relationship with an 80-year-old retired probation officer in Pflugerville that caused him to get mad at the man on the day he killed him, according to an arrest affidavit released Wednesday.

Austin police said Tuesday that Meza, 62, is a serial killer responsible for the deaths of at least three people. Police said they are looking for links between him and up to 10 other unsolved homicides. Meza was arrested Monday without incident in North Austin. Officials said he had a backpack with him containing duct tape, zip ties and a .22-caliber gun.

He was charged May 25 with capital murder in the death of Jesse Fraga, a retired probation officer who befriended him and allowed Meza to live with him at his Pflugerville home, police said. Meza also stole Fraga's truck, investigators said.

He also was charged this week with murder in the death of Austin resident Gloria Lofton in 2019 after he called police and confessed to it on May 24, police said Tuesday. Officials were able to match DNA at the scene to Meza.

Meza had been convicted of murder in the 1982 sexual assault and strangulation of 8-year-old Kendra Page.

Fraga, the most recent person that Meza is accused of killing, had befriended him when Meza was first released from prison in 1993 and having a hard time finding a place to live, according to a lawsuit.

Police learned of Fraga's death after his niece asked them to check on him May 20, the affidavit said. It said officers found Fraga's body in a bathroom and blood at the scene.

When officers arrived at Fraga's house on Camp Fire Trail, there were two people there who said they knew Meza and Fraga. One of them said she was a friend of Meza's and said Meza was Fraga's caregiver, the affidavit said.

The woman "stated that she got a feeling that something bad had happened to Raul and wanted to go by the house," according to the affidavit. It said Meza had made a statement that she interpreted "as a suicidal statement."

The other person at the scene, a man, said the woman was his neighbor and Meza's girlfriend, the affidavit said.

It said the man had picked up Meza on May 13 from a hospital where Meza was being treated for kidney stones. The man said that after he picked up Meza, Meza said "I f---ked" up!" according to the affidavit. "(He) then observed Raul make a gesture with his hand as if he was slicing someone's neck," the document said.

Police said Fraga had a punctured neck and a broken cervical spine. Meza had agreed to move out of Fraga's house and did so on May 12, according to a search warrant.

Lofton, who died in 2019, was strangled, police said Tuesday. Her death at the time was called suspicious because investigators were not able to determine how she died until Meza confessed to strangling her, police said.

Some of Lofton's neighbors said this week they thought the 66-year-old died of natural causes at her home in the 4800 block of Sara Drive.

They described her as a kind and trusting woman. She was private, they said, but she had a big heart, and she often let strangers live with her if they needed.

“She helped everyone she could,” said Sergio Rodriguez, a friend and former roommate. “She was a good lady, a tough lady.”

Rodriguez said he didn't learn Lofton had been killed until about a month after her death, when he spoke to her daughter about it. He had known her since he was a child because his family lived across the street from her house, and he used to help Lofton’s father with chores and errands. Years later, Rodriguez said, he was one of the many people who took shelter with Lofton.

In the mid-2000s, he moved in with her and started paying rent. He lived there for about a year before a dispute over rent payments drove him to move next door with a roommate. Despite the move, Rodriguez said he maintained contact with her for years and admired her generosity.

Eventually, Rodriguez said he started to worry whether that generosity extended too far. He suspected Lofton might have been developing memory issues, and said he grew increasingly concerned she was opening her door to people she couldn’t trust. When he shared her concerns with her, Rodriguez said he was met with resistance.

“There were always people coming in and out of there,” Rodriguez said. “I told her to be careful, but she would always get mad.”

Rodriguez and other neighbors said they didn't know if Meza ever stayed with Lofton or if the two knew each other. According to public records, Meza once lived next door to Lofton.

The case that Meza has been most notorious for is the murder of Page, whose body was found by a dumpster at Langford Elementary in 1982.

One of Page's brothers, Kevin Page, said Wednesday that he can still remember the day his little sister died.

"Me and my brother rode bicycles and saw her body before the cops did," he said.

Page said he was unable to go to work Wednesday after hearing that Meza had been accused of more murders.

"I'm definitely angry," he said. "I'm heartbroken. I cried a lot yesterday because of the whole thing. It brings back a lot of memories."

Page said Meza is a "sick man" who never should have gotten out of prison. "I just really feel like the judicial system didn't do their job."

Another of Kendra's brothers, Cary Page, said Wednesday that he wasn't surprised Meza had been charged with other murders.

"He is a serial killer, which I knew he would become all along," Cary Page said. "I saw what he did to my sister. Meza had piled a Christmas tree and a bike on top of Kendra Page's body to hide her."

He said his family, including himself, had tried to persuade authorities to keep Meza in prison by going to his parole hearings.

Meza was sentenced to 30 years after pleading guilty to Kendra Page's death, but he was released after the time he served plus additional time counted for good behavior equaled the length of his sentence under the state's mandatory supervision law, which has since been changed.

Police were disappointed that Meza was offered a plea deal instead of standing trial, interim Assistant City Manager Bruce Mills said Tuesday. Mills was an Austin police officer when Kendra Page was killed.
