A West Ashley High School teacher charged last week with a raping a woman drove his car into a tree and died this morning in Florence County, authorities said.

A suicide note was reportedly found in Scott Larue Knight's car, but emergency workers were still clearing the scene and further details were unavailable, said Charleston County Sheriff's Maj. John Clark.

Florence County authorities could not immediately be reached for comment.

On Friday, Charleston County deputies arrested, Knight, 39, on charges of third-degree criminal sexual conduct and assault and battery of a high and aggravated nature. Affidavits describe an attack in September at Knight's home at Concord West of the Ashley on 45 Sycamore Ave.

Knight is accused of pushing a woman in her early 30s into his room and locking the door, then forcibly raping her, Clark said. Knight was arrested at home. He left the Charleston County Detention Center on Saturday after posting $20,000 bail, according to court documents and the jail.

Knight had been on administrative leave from his teaching job since being arrested Nov. 14 on two counts of first-degree harassment, according to the school district.

Student complaints about Knight go back to June, when a 16-year-old girl reported him making off-color remarks about her to her boyfriend, an arrest affidavit states. Her parents made a report to the school's administration. She claimed he continued trying to make conversation with her this school year and would stand outside her classroom door and stare.

A 14-year-old girl also reported him making inappropriate comments.
