OREGON – The Federal Bureau of Investigation’s Portland Field Office is asking for the public’s help in identifying potential victims of a violent sex assault offender who has lived in at least 10 states. 

29-year-old, Negasi Zuberi (aka Sakima, Justin Hyche and Justin Kouassi), is in federal custody for interstate kidnappingafter a Washington woman escaped his home in Klamath Falls, OR, claiming she was kidnapped, sexually assaulted and locked in a dungeon. 

According to court records, on Saturday, July 15, 2023, Zuberi traveled from his home in Klamath Falls, OR to Seattle, WA where he solicited the services of a prostitute, he then posed as an undercover police officer. The victim told investigators that he pointed a taser at her and placed her in handcuffs, leg irons and put her in the back seat of his car. He then traveled roughly 450 miles with the woman, sexually assaulting her during the trip.


According to the victim, once he arrived at his home in Klamath Falls, OR, Zuberi moved her into a makeshift cell that he had constructed in his garage. The cell was made of cinder blocks and a metal door installed in reverse so it could not be opened from the inside. Once Zuberi left, the victim says she repeatedly banged on the door and was able to break the door open and escape the room. She was able to flag down a passing motoristwho called 9-1-1.

Klamath Falls Police Department obtained a search warrant for Zuberi’s residence and found the makeshift cell described by the victim. Zuberi fled and was located in Reno, NV where he was taken into custody after a brief standoff with local police. 

“This woman was kidnapped, chained, sexually assaulted, and locked in a cinderblock cell. She beat the door with her hands until they were bloody in order to break free. Her quick thinking and will to survive will undoubtably save other women from a similar nightmare,” says Assistant Special Agent in Charge, Stephanie Shark with the FBI Portland Field Office. “We are fortunate that this brave woman escaped and alerted authorities. Through quick law enforcement action we were able to get Zuberi in custody within 24 hours. While she may have helped protect future victims, sadly we have now linked Zuberi to several violent sexual assaults in at least four states and we believe there may be many more.”

Zuberi has lived in ten states over the last ten years and FBI investigators have reason to believe there are several more sexual assault victims. 

The FBI believes he primarily targeted sex workers or roommates in California, Washington, Oregon, Colorado, Utah, Florida, New York, New Jersey, Alabama, and Nevada between the timeframe of August of 2016 to July of 2023.  

Zuberi is known by many victims as “Sakima.” He is believed to have several different methods to gain control of his victims to include drugging their drinks, pretending to be a police officer, and soliciting the services of sex workers and then violently sexually assaulting them. Some of the encounters may have been filmed to make it appear as if the assault was consensual. The victims are threatened with retaliation if they notify the police.
