A former Beadle County janitor indicted last September on two counts of sexual contact with a child under the age of 16 has pleaded not guilty.
The trial for Fred Sylaart is set for March 6 in Beadle County.
His 18-year-old son, Jordan Sylaart, is charged with two counts of first-degree rape.
Prosecutors say the alleged incidents involved girls under the age of 12 who attended a day care ran by Fred Sylaart's wife. The day care is currently closed.
Former Brown County States Attorney Kimberly Dorsett is acting as special prosecutor in the case because Fred Sylaart is a former county employee.
