A Sheldon High School assistant coach who also teaches middle school in Springfield was arrested at his home in Eugene on Saturday and charged with sexually abusing a 15-year-old female student at the high school.

Chad Ger-ald Schacht, 40, coached cross country at the high school and taught sixth grade science, math and physical education at Agnes Stewart Middle School in Springfield.

He was held at the Lane County Jail on two counts of third-degree rape and one count each of third-degree sodomy and second-degree sexual abuse. All charges are Class C felonies. Bail had not been set Saturday night.

Eugene police spokeswoman Melinda McLaughlin said staff members at Sheldon reported information about Schacht and the student to the police “a couple days ago.” The alleged crimes took place in Eugene, she said.

Schacht was arrested at 3 p.m. Saturday without incident, McLaughlin said.

He was hired in September 2005 as a part-time assistant cross country coach at Sheldon, said Kerry Delf, the communications coordinator for the Eugene School District. Schacht was suspended from his coaching job at 5 p.m. Thursday and placed on administrative leave, she said.

Sheldon principal Bob Bolden e-mailed Sheldon parents and staff members about the matter Saturday evening.

“I can assure you that nothing is more important to this school and district than the safety and well-being of each of our students,” the e-mail said, noting that it was Sheldon staff members who first alerted police. “I hope you will not let the alleged misconduct of one person cast a shadow over all of our staff members.”

Schacht is a full-time teacher at Agnes Stewart Middle School and has worked for the district for about 10 years, said Springfield School District spokesman Jeff DeFranco.

“He will not be returning to work in the near future, pending the results of this investigation,” DeFranco said.

Despite the investigation, Schacht taught at the middle school on Friday, DeFranco said.

“We were not contacted about this issue until after the school day on Friday,” he said.

DeFranco added that Springfield school officials have had no indication that any Springfield students were victims in the case.

“There is nothing we have heard of at this time,” he said.

Eugene Police are investigating whether there may have been more victims.

Police asked with information to telephone Detective Dan Braziel at 541-682-5836.
