CLEVELAND, Ohio – The former Lakewood High School band director, who lost his job after being accused of sexual battery, told authorities that he picked up a 16-year-old boy June 10 and spent the day with him having sex, showering together and seeing a movie.

After the movie, Nathan Harris said, he and the youth drove to the Rocky River Reservation of the Cleveland Metro Parks and parked near the Lorain Bridge about 10:20 p.m. There, he said, he and the youth had sex again.

"It was at that point that the ranger on duty shone his spotlight on the vehicle,'' Harris said in his statement to authorities.

The statement was filed in Cuyahoga County Common Pleas Court and has become a flashpoint in Harris' case. He is charged with two counts of sexual battery. He is free after posting $40,000 bond.

Harris' lawyer, Larry Zukerman, is seeking to have the statement thrown out. He said in court documents that park rangers began questioning Harris before they gave him his Miranda rights. Later, they transported Harris to the ranger headquarters and read him his rights, Zukerman said.

Jennifer Driscoll, an assistant Cuyahoga County prosecutor, said in court documents that the key issue in the case "is a matter of investigative detention versus custody.''

Driscoll said that soon after the ranger first approached the car, Harris was placed in "investigative custody.'' She said that police are permitted to detain a person briefly to determine what is going on.

She said park rangers found Harris nearly naked and the boy, a student of Harris' at Lakewood, completely naked. Minutes after he was arrested and read his Miranda rights, Harris made a voluntary written statement.

Common Pleas Judge Daniel Gaul set a hearing Oct. 16 on whether the statement should be thrown out.

Harris said in a videotaped interview that he and the youth would text, iMessage and Snapchat. He said in his written statement that he contacted and picked up the youth at 9 a.m. He said he and the youth "returned to my apartment and proceeded upstairs.''

They left his apartment in Lakewood about 3:30 p.m., ate and went to a movie theater in Cleveland Heights to see latest X-Men film. After the movie, they drove to the Metro Parks.

The last line of the statement reads, "I am the band director at Lakewood High School.''

Harris had been in the school district for two years. He also had served as the band director at Harding Middle School. A district spokeswoman declined to comment earlier this summer, saying "Nathan Harris is no longer a district employee.''

After Harris was initially charged, Lakewood schools released a statement on the case, saying it was banning Harris from the district.

"Our thoughts are with the student and the student's family," said Superintendent Jeff Patterson. "We will be working with them to provide appropriate counseling and support services as needed and we will provide services to any other student who may need counseling and support as well."
