"We're just very thankful for the jury's decision on all five counts," Cohn said. "We're much relieved, and our client is much relieved that he can move on with his life."
According to Cohn, the district put Ontiveros on administrative leave without pay in January 2010, and his future with Oxford Academy remains unclear. District officials could not be reached Wednesday afternoon.
The student, Cohn said, was a senior at the time of the alleged acts and has since graduated.
Deputy District Attorney Angela Hong, who led the prosecution, called the verdict an "extreme disappointment."
The case, she said, began in 2009 when the student's mother discovered text messages from Ontiveros on her daughter's phone and reported them to the principal, who in turn called police. A forensic analysis of Ontiveros' phone revealed identical phrases to those that appeared in the student's inbox, Hong said.
Cohn, though, said those phrases could have been saved in the phone's memory from e-mails, Internet searches or other sources, and that the student may have used a computer to send text messages to her phone to give the appearance of having been contacted by Ontiveros.
The student's phone, he said, did not have any saved text messages that she had sent to Ontiveros.
