Character mistake: Dr. Sloan and Quinn are in the victim's apartment. Right before Dr. Sloan opens the door for the old lady witness to ID Quinn, Dr. Sloan says, "saw a man visiting Holly the night before he died." Holly is a woman. Dr. Sloan should have said "she." (00:33:51)
Diagnosis Murder (1993)
1 character mistake in season 7
Starring: Dick Van Dyke, Barry Van Dyke, Charlie Schlatter, Victoria Rowell
Factual error: Early in the show, 3 Marine officers are being questioned about the death of a 4th. All 3 are wearing the Marine insignia on their jacket lapels reversed. [The anchors should point IN, not out] That mistake is corrected for some characters later in the episode, however at least two of the officers are seen later without their jackets, and their shirts do not have military creases - 2 in the front, 3 in the back - standard for a Marine blouse.
