The ex-husband is stated as living near Philadelphia in Camden, PA. Camden is actually located in New Jersey, across the Delaware River from Philadelphia. This is not entirely correct. When the victim's mother tells Briscoe and Green that her ex-husband lives "near Philadelphia" this would be accurate as Camden, New Jersey is only 5 miles from Philadelphia. However, the title card preceding Briscoe and Green's meeting with the ex-husband incorrectly states the location as "Camden, Pennsylvania" which doesn't exist.
When the coroner is asked if there was any sign of sexual assault, he replies, "None that I could see." Since the victim was completely clothed, the coroner had no way of telling one way or the other whether she was sexually assaulted until he examined her unclothed body at the morgue.
