Former pastor arrested in 1975 murder of young girl walking to his church

On. Aug. 15, 1975, 8-year-old Gretchen Harrington was walking to Bible camp in a township outside Philadelphia when she was kidnapped and killed.

On Monday, authorities said a man who had been the pastor of one of the camp's host churches has been arrested and charged with Harrington's murder.

The Delaware County District Attorney's Office said David Zandstra, 83, recently confessed after he was confronted with new evidence, including a witness' allegations that the former pastor had groped her and may have tried to kidnap another local girl.
