PORTLAND, Ore. (KOIN) — A driver accused of killing 15-year-old Fallon Smart on SE Hawthorne Boulevard in August 2016 removed the GPS monitoring device he had been wearing since being released on bail, police said.

Abdulrahman Sameer Noorah, 21, bailed out of jail in September 2016 and was placed on house arrest.

KOIN 6 News learned the consulate of Saudi Arabia posted Noorah’s $100,000 bail on September 9, 2016, and he had been under Close Street Supervision ever since. But on Sunday, Noorah reportedly removed his electronic monitoring device.

Now Portland Police Bureau and Crime Stoppers of Oregon are asking for the public’s help finding him.

“He is not home and our attempts to locate him have been unsuccessful,” court records state. “He is accordingly in violation of his pre-trial release conditions to abide by GPS monitoring requirements and house arrest; a warrant for his arrest is respectfully requested.”

Noorah is described as a Saudi Arabian man, 6’1″ tall and 150 pounds. He was last known to be in the area of SE 106th Avenue and SE Division Street.

Police are concerned he is having a mental health crisis as a result of his pending trial.

Court records show he had a court hearing on June 8 and another scheduled for June 20. He has warrants for 1st-degree manslaughter, reckless driving, failure to perform the duties of a driver (hit-and-run) and recklessly endangering another person.

As part of his release agreement, Noorah was not allowed to drive, use any kind of intoxicant, contact any witness, or the victim’s family. He had to turn over his passport to the U.S. Department of Homeland Security.
