While several students reported the issue this past week, police are unsure if it has been an ongoing problem, assistant Chief Robb Parthemore said.
One of the students involved may have hired an attorney, Perkins police Chief Ken Klamar said.
Police were first notified of the situation last Tuesday. They first provided an incident report Monday, after the Register requested one Friday. The report contains a three-sentence narrative stating school resource officer Dan McLaughlin met with the district's superintendent and athletic director at their request about a "safety concern." It does not mention drugs or the investigation.
"The information was explained by (athletic director Mike Strohl) and the information will be addressed as time permits," the report states.
The coach, Tracey Hiss, allegedly provided students with adhesive Lidoderm patches, which contain the drug lidocaine, Klamar said.
Lidoderm patches are placed on the skin to numb areas for temporary pain relief, according to the U.S. Food and Drug Administration's website. Side effects typically include a range of temporary skin irritations or allergic reactions. Rarely can an individual overdose on local anesthetics such as lidocaine, but serious side effects are possible.
Providing a student with a seemingly harmless drug may not appear dangerous, but coaches and teachers must consider all possibilities, district parent Nancy David said.
"You never know what sort of allergic reaction someone might have," David said Monday while waiting to pick up her daughter at Perkins High School. "It's illegal for teachers to do that for a reason. People just don't think sometimes."
Perkins Schools superintendent Jim Gunner gave Hiss a written notice of her suspension Tuesday, pending the outcome of the investigation. She is prohibited from school grounds and is not permitted to discuss the matter with any students or employees, according to the letter.
Gunner declined to provide further information, citing the ongoing investigation.
Hiss has been varsity girls track coach for 25 years. She is also a health teacher at Briar Middle School for sixth-graders and junior high students.
