Criminal charges have been dropped against a bus driver formerly accused of inappropriately touching a special needs boy.

The Ramsey County attorney’s office dismissed the case against Charles E. Glover, 53, on Monday.

“GPS data from the bus that the defendant drove does not register a stop in the park where the victim said the incident occurred,” said a letter written by Assistant Ramsey County Attorney Andrew R.K. Johnson. “Thus, without additional evidence, the State is unable to prove the allegations beyond a reasonable doubt.”

Glover had been charged earlier this year with one count of second-degree criminal sexual conduct after a 5-year-old boy said Glover touched him in Mounds Park in 2015.

The boy was interviewed at the Midwest Children’s Resource Center, and said that while at the park, Glover pulled the boy’s pants down and squeezed the boy’s genitals.

Glover was a driver for Twin City Transportation, which has provided special needs transportation services since 1989.

Glover was accused of inappropriately touching a 10-year-old boy’s genitals in 1998, and denied the encounter. Criminal charges were never filed. He also was accused in 2010 of possessing child porn involving boys on his computer. He denied those allegations as well, and charges were never filed.
