ROSEBURG, Ore. (CBS) -- An Oregon teacher has been accused of having a sexual relationship with a student.

Lt. Chris Merrifield of the Douglas County Sheriff's Office said Monday that 29-year-old Andrea Baber was arrested after investigators obtained a warrant to search her Cottage Grove home.

Baber taught at Logos Christian Academy in Springfield.

Merrifield says the relationship began in 2016, when the male student was 15 years old. Merrifield says the relationship continued on a regular basis, with Baber also providing the boy with marijuana.

Baber is charged with third-degree rape, third-degree sodomy, unlawful delivery of marijuana to a minor, online sexual corruption of a child and contributing to the sexual delinquency of a minor.

CBS affiliate KPIC reports that on December 15, detectives obtained a search warrant for Baber's residence where detectives say they located additional evidence.

The sheriff's office identified Baber as a former teacher, but she remains on the school's online staff directory. The website says Baber teaches writing and literature, and is married.

"Andrea has always felt called to work with youth and is very excited that God opened the door for her to be part of the Logos team," her biography says, according to KPIC.
