STURGEON BAY (AP)-- A 39 year-old Sturgeon Bay High School teacher has been charged with having sex with a student.
Darren Berg was arrested last month after authorities say a teenage girl confessed to having a relationship with him. He was charged Monday with three counts of sexual assault of a student by school staff.
Door County prosecutors say they have incriminating text messages between Berg and the girl.
The criminal complaint says she told police they had sex last summer at her home after babysitting his children. It says she also told police she thought Berg might have victimized other girls at the school.
Berg teaches math and coached track at Sturgeon Bay High School. He's been on paid leave since Feb. 2.
