There may be Alabama victims of an Oregon man facing interstate kidnapping charges for allegedly holding a Washington woman captive in a makeshift cinderblock cell and sexually assaulting her, the FBI said Wednesday.

The investigation into Negasi Zuberi, 29, of Klamath Falls, Oregon, has expanded to nine other states, including Alabama, where he lived for portions of the last nine years.

“We’re looking at anyone where he has lived because he’s moved around quite frequently,” said Joy Jiras, a spokeswoman for the FBI’s Portland field office, which held a news conference Wednesday appealing for possible victims to come forward.

Zuberi lived in Tuscaloosa from around June 2014 to April 2015 and Northport from roughly June 2018 to April 2020.

He left his home in Klamath Falls to Seattle on July 15, where he solicited a prostitute while posing as a police officer, the FBI said, citing court records.

The woman told authorities Zuberi pointed a Taser at her and put her in handcuffs and leg irons before putting her in the back seat of his car.

Zuberi then traveled about 450 miles with the woman, sexually assaulting her during the trip.

When Zuberi and the woman arrived at his home in Oregon, he put her in a makeshift cell he built in his garage. The cell was made of cinder blocks and contained a metal door installed in reverse so it could not be opened from the inside.

Once Zuberi left, the woman repeatedly banged on the the cell door, bloodying her hands in the process, until she was able to break the door down. She then flagged down a passing motorist, who called 911.

The woman’s “quick thinking and will to survive may have saved other women from a similar nightmare,” said Stephanie Shark, assistant special agent in charge of the FBI’s Portland field office, in a statement.

“We are fortunate that this brave woman escaped and alerted authorities. Through quick law enforcement action, we were able to get Zuberi in custody the next day,” Shark continued. “While she may have helped protect future victims, sadly we have now linked Zuberi to additional violent sexual assaults in at least four states, and there could be more.”

Klamath Falls police obtained a search warrant for Zuberi’s home, where they found the makeshift cell described by the woman.

Zuberi, who is also known as Sakima, Justin Hyche and Justin Kouassi, fled the area and was found in Reno, Nevada, where he was taken into custody following a brief standoff with local police.

He has lived in 10 states in the last decade, including Alabama, and the FBI believes there may be other sexual assault victims of Zuberi.

Besides Alabama, the FBI has extended the investigation to California, Washington, Oregon, Colorado, Utah, Florida, New York, New Jersey, Alabama, and Nevada.

Victims may know Zuberi by “Sakima,” the bureau said.

He may have used different methods to gain control of his victims, including drugging their drinks and impersonating a police officer.
