A woman who escaped a cinderblock cell in a man’s garage in Klamath Falls, Oregon, was abducted hundreds of miles away last month in Seattle, and now authorities are looking for more potential victims across multiple states.

The man, 29-year-old Negasi Zuberi of Klamath Falls, posed as an undercover police officer and kidnapped the woman in the early morning hours July 15, then shackled, sexually assaulted her and locked her up, according to court records.

He was arrested and federally charged with interstate kidnapping, which carries a maximum sentence of life in prison if convicted, Assistant U.S. Attorney Nathan Lichvarcik said at a news conference Wednesday.Authorities said Zuberi has been linked to sexual assaults in at least four more states, and they are searching for more potential victims. He’s lived in multiple states since 2016, possibly including California, Washington, Oregon, Colorado, Utah, Florida, New York, New Jersey, Alabama, and Nevada, the FBI said.

Fighting for her life, she escaped bloodied

The victim in Klamath Falls, who wasn’t identified, “briefly slept and awoke to the realization that she would likely die if she did not attempt to escape,” according to a criminal complaint.

A woman escaped a makeshift cell in Klamath Falls, Oregon, where she was held after being kidnapped in Seattle in July, authorities said.

The “makeshift” cell was made of cinderblocks and a metal door that had been installed backwards so it couldn’t be opened from the inside, the complaint said. There was also an exterior door, and the cell had been built to be soundproof, Klamath Falls police said in a press release.

She banged against the door, bloodying and bruising her hands, until she managed to open it, the FBI in Portland said Wednesday. According to Klamath Falls Police Captain Rob Reynolds, the victim was able to break welds on the door, rip a metal screen off of it, and crawl out. She had lacerations on her knuckles from punching the door and walls, Reynolds said.

She then retrieved a gun that belonged to Zuberi and escaped. She climbed over a fence and flagged down a driver who called 911.

“The woman fought for her life, beating the doors and the walls of this cell with bloodied hands,” Stephanie Shark, the assistant special agent in charge of the FBI’s Portland field office, said Wednesday. “The victim’s focus, actions and her will to survive triggered a law enforcement response that may have actually saved many other women from a similar nightmare.”
