Well, my informant says that legend has it that in the fall of 1959 a couple of thespians staged/performed a "murder" at 14th & Mass.
The first car (northbound I believe) came to the stoplite.  The victim (was it Ward R.?) was ejected from the car.
The second car pulled up alongside, a sound of an automatic machine-gun was heard.  Blood (ketchup) spewed forth from the victim.
The victim was scooped up from the pavement and removed from the scene.
Allegedly, both cars were secreted in a garage belonging to either Bob A or another individual (C. A.-in class of 60).  One car was thought to have a scanner.

Vice Prin HC Stewart was intent on uncovering the participants even though the event was off campus. There was quite a stir in the HS office (mostly by HC).  He either could never find out or gave up. It was also rumored that an elderly customer of the drug store suffered ill effects of the stunt.

Perhaps someone else knows of this and can shed a more accurate account
