Captain Daniel Pitta recorded being flagged down by Stella Medeiros at 11:25 pm, who described the two victims laying on the turnout floor. He radioed Benicia Police Department, where Officer Pierre Bidou had just pulled into the parking lot with his partner. Pierre Bidou stated "During that night we had served a search warrant at what we call The Cottage at Lake Herman which was owned by the city of Benicia, a narcotics search warrant my partner and I, we confiscated about a pound and a half of marijuana, which in the 1960s was a big drugs bust, today it wouldn't get very high on the Richter scale. We had left and were heading back to the police department to put the marijuana into evidence and as we drove by we didn't see or observe anybody in that area, there's a turn there (the crime scene turnout) and your headlights shine right in there as you go by. As I was pulling into the lot at the police department we heard the Benicia Police Department dispatcher put out a call of a possible shooting and victims on Lake Herman Road and described the location. My partner and I turned around at that time and responded to the call". Captain Daniel Pitta would have took the details from Stella Medeiros and relayed them to the Benicia Police Department dispatcher, who then "put out the call", which was heard by Officer Pierre Bidou as he pulled into the parking lot. He stated he immediately turned around and headed back to the Lake Herman Road turnout.
It was estimated that Robert Connelly and Frank Gasser left the area (heading to Benicia) at approximately 11:05 pm. Officer Pierre Bidou passed the turnout at approximately 11:13 pm. That means the Rambler was sitting on the west bank for eight minutes, but had then relocated just one minute or so later when James Owen passed. This must have been the crucial period when the Zodiac Killer pulled up behind the Rambler and ushered it back across the turnout. It may very well have been seconds before James Owen passed. Had it been too long, then Owen would have either seen the attack or the bodies laying on the turnout floor (which he didn't). He also failed to see any occupants in or around the vehicles. They had to be situated in their vehicles. He most likely just failed to notice them.
