A 52-year-old former police officer was arrested after police said he tried to pass himself off as a high school student. Police said Christopher Schildt, 52, a retired police officer, gained access to Waterford High School Thursday morning. They said Schildt tried to pass himself off as an 18-year-old student and sat in a class. School officials said they thought Schildt, who looks youthful for his age, was a transfer student from Florida. Schildt told school officials he was registering his 18-year-old nephew, who had the same name and the alleged teen had medical issues and would appear older.
