MARION, Iowa (AP) — Linn County authorities in eastern Iowa have arrested a school nurse who’s accused of having sex with a 16-year-old student. Cedar Rapids police say 46-year-old Angela Beik is being charged with sexual exploitation by a school employee. Beik was the school nurse at Linn-Mar High School in Marion and also employed at St. Luke’s Hospital in Cedar Rapids. Police began an investigation of Beik last month. They’d learned that state officials were checking a report that Beik told fellow St. Luke’s nurses that she’d had consensual sex with the boy. They reported the conversation to officials.
