STANISLAUS COUNTY, Calif. (KTXL) — Detectives are looking for more victims of a handyman who allegedly broke into a Stanislaus County woman’s home Friday morning and sexually assaulted her.

Around 7:30 a.m., a woman reported waking up to someone in her home, the Stanislaus County Sheriff’s Office said.

“That was absolutely a violation of a person’s sanctity of their home,” Stanislaus County Sheriff’s spokesman Sgt. Luke Schwartz told FOX40. “This kind of thing can take place at any time, day or night.”

The woman told deputies a masked man armed with a handgun came into her bedroom, the sheriff’s office reported. He then tied her up, choked her and sexually assaulted her.

Before leaving, the masked man stole the woman’s ATM card and threatened her, telling her not to call police once he was gone.

“Through the course of that follow-up investigation, were able to identify the responsible individual that afternoon and make an arrest and take this individual into custody,” Schwartz said.

The sheriff’s office said detectives with its Crimes Against Persons Unit determined the suspect was 40-year-old Jose Luis Ramos Rivera, a handyman who had worked for the woman for several months.

“It happened to be someone that she had done business with previously,” Schwartz said.

When she hired Rivera, the woman took a photo of his ID, which the sheriff’s office said helped “in his apprehension the same day he committed the crimes.”

Rivera was booked into the Stanislaus County Public Safety Center and faces multiple charges, including robbery, home invasion and assault with the intent to commit rape.

Stephanie Barraza with Haven Women’s Center-Stanislaus, an organization that advocates for sexual assault survivors, told FOX40 that it was brave of the woman to come forward in this case.

“It is courageous when somebody comes forward and talks about such a traumatic incident,” Barraza said. “It takes so much vulnerability to, you know, come forward and say, ‘Hey, you know, this occurred to me and now, you know, I don’t want it to happen to somebody else.’”

The women’s center provides services to survivors.

“We meet them where they’re at in terms of what they want to do, if that is a restraining order, if a safe location, individual peer counseling,” Barraza said.

Stanislaus County detectives said they believe Rivera may have more victims. However, they aren’t releasing Rivera’s mugshot because they said it could compromise future investigations.

They’ve asked anyone who was a victim or knows a victim to call Detective V. Esquivez at 209-567-4466. They can also make an anonymous tip by calling Crime Stoppers at 209-521-4636 or going to

“We urge them to come forward and talk to our detectives so we can make sure that he’s held accountable,” Schwartz said.

Barraza has a message for all survivors who may feel isolated: You are not alone.

“Our job is to believe and understand,” Barraza explained. “Nobody deserves to go through something like that and you don’t have to heal by yourself. There is a community out there that can lend a hand.”
