Retired Mendota High School science teacher John G. Holzman is accused of sexual misconduct with a student.
The 56-year-old Holzman was arrested Monday from the 600 block of 19th Street in Mendota.
Mendota police say the arrest followed a weeks-long investigation that involved electronic messages, phone records, and photographs.
Holzman posted bond to be released.
The school district had no comment.
Holzman retired in last month. He was also a volleyball coach.
His first court date is scheduled for Thursday.
