CHARLESTON -- A substitute teacher with the Charleston school district was arrested Thursday by the U.S. Marshals Service on a Texas warrant for being a fugitive from justice on a charge of indecency with a child.

A school district press release issued Friday reported that the U.S. Marshals Service contacted district officials on Thursday with information that Adrian Rivas, an at-will substitute teacher in the district, was wanted as a fugitive from justice for arrest in Texas on outstanding felony charges. District officials cooperated with the U.S. Marshals Service and Charleston Police Department, and Rivas was taken into custody.

Detective Sgt. Tony West of the CPD said Rivas was arrested at approximately noon Thursday while he was working at Jefferson Elementary School, but law enforcement personnel took him into custody outside of the school building.

"The arrest was outside the view of the children," West said, adding that the arrest occurred without incident. Inmate records at the Coles County jail show that Rivas, 39, was confined there at 12:20 p.m. Thursday following his arrest. West said the warrant was issued out of Montgomery County, Texas.

Coles County State's Attorney Brian Bower said the warrant was issued on Jan. 19 and the face of the warrant document listed indecency with a child as being the State of Texas charge that led to the warrant being issued.

Justin Hamrock, a supervisory deputy with the U.S. Marshals Office, said their Central Illinois task force that is based in Urbana was recently asked by the U.S. Marshals Service office in Houston to arrest Rivas on the Montgomery County, Texas, warrant. Hamrock said the Houston office took this action after finding out that Rivas was living in the Charleston area.

Hamrock said Rivas will be extradited to Montgomery County, Texas, and he referred further questions on the felony charges against Rivas to authorities there. They could not be reached for comment late Friday afternoon.

The Charleston school district's press release reported that every employee in the district, including Rivas, must undergo and pass a criminal background check that includes FBI fingerprinting as a condition of employment. The district reported that Rivas worked intermittently as a substitute teacher from Oct. 18 until Thursday and that his arrest was not related to his employment in the district.

Burgett and West said they believe that the felony charges against Rivas were filed and the arrest warrant was issued sometime after he passed his background check with the school district.
