HILLSBORO, Ore. -- A Hillsboro man who works as a substitute teaching aide has been arrested on suspicion of sexually abusing a girl at his home.
Police booked Rafael Abinacer, 41, in the Washington County Jail on Thursday on charges of first-degree sexual abuse, first-degree sodomy and second-degree sodomy. He is being held on $250,000 bail.
Investigators believe there may be more victims and said more charges could be forthcoming.
Detectives said they received a tip on Wednesday that Abinacer had sexual contact with a girl younger than 14 and that he sexually assaulted her on "numerous" occasions over an extended period of time.
Investigators did not reveal how Abinacer knew the girl, but said they have not received any reports of victims from the schools.
Abinacer was a substitute teaching aide who contracted with the Hillsboro School District. He primarily assisted with special education classes at Lincoln Elementary School in Hillsboro, police said.
"Sheriff's detectives are concerned with Mr. Abinacer's access to children in the schools," a Washington County Sheriff's Office news release said.
Employed the school district since March, Abinacer assisted in more than 10 schools. In addition to Lincoln elementary, they include: Jackson Elementary School, W.L. Henry Elementary School, Minter Bridge Elementary School, Brown Middle School, Evergreen Middle School, South Meadows Middle School and Liberty High School. With the exception of Lincoln, Abinacer only worked one day in each of these schools.
The Hillsboro School District issued a press release Friday, saying officials are in the process of terminating Abinacer.
Abinacer had been convicted in 1993 in New York of felony possession of a non-registered firearm. But school officials said in the news release that the nature of the crime and time since the conviction didn't preclude him from a substitute position.
Further, school officials said the school district has not received any complaints about Abinacer.
Detectives are hoping any possible victims who have not reported abuse will come forward. Anyone with information on Abinacer should call the Washington County Sheriff's Office at 503-846-2500.
