ST. LOUIS COUNTY, Mo. — A former Lindbergh High School teacher was charged Thursday with having sexual contact with a student, and police believe there may be more victims.

Grant Gaumer, 37, also faces two counts of statutory sodomy in the second degree. Police said Guamer made sexual contact with a student under the age of 17 earlier this year, between March 1 and March 31, while still a teacher at Lindbergh High School.

Gaumer had been a teacher at the high school for eight years. He was also the assistant water polo coach and the teacher liaison for the Gay-Straight Alliance group at the school. Amid the investigation, the district confirmed he no longer works there.

Investigators suspect that there may be additional victims due to the amount of interaction he had with students. Staff members in the Lindbergh School District are cooperating with authorities.

Gaumer is being held on a $500,000, no 10%, cash bond.

Anyone with information should call the St. Louis County Police Department at 636-529-8210.
