PONTE VEDRA, Fla. -- Instead of being in school, a Ponte Vedra High School employee was in court on Tuesday after being arrested and accused of using the Internet to solicit sex from a 16-year-old boy.

Investigators tracked William Turner Online for several weeks after police received a tip from an out-of-state law enforcement agency that the 46-year-old man might be trying to contact underage boys.

Earlier this month, police were notified that Turner had contacted a teenage boy on the Internet and e-mailed the teen pictures of male genitalia.

A cyber-crime investigator located the boy and his parents and was given permission to take over the boy's Yahoo account. Officials said Turner sent another e-mail offering to meet the teen for a sexual encounter on Monday morning at the McDonald's on Emerson Street. When Turner arrived, police were there to arrest him.

"I couldn't even express how disappointed I was," said Ponte Vedra High School Principal Craig Speziale. "I'm angry. I'm angry that this has happened. I'm angry for everyone associated with this school. It casts a dark cloud."

This year was Turner's fourth in the St. John's County school system. It was his first year coaching at Ponte Vedra High School.

The school system and the Attorney General's Office said Turner has no prior record.

Turner was an assistant coach for the Ponte Vedra football team, and during the school day he assisted a special-needs student in class. Investigators told Speziale there was no evidence that Turner had done anything inappropriate with his student.

"Nothing that would bring suspicion -- he was on time to work. He had a good rapport with the student that he worked with," Speziale said.

"We don't have any information if this has been going on with other children. We will find that out when we conduct forensics on the computer. We have seized the computer," said director of the Child Predator Cybercrime Unit Maureen Horkan.

Turner was in court Tuesday morning. He faces three felony charges and is being held in jail on $25,000.
