Here is the section regarding LeRoy Sweet in the October 12th 1969 police report: "Assistant traffic manager of Yellow Cab, LeRoy Sweet responded and gave reporting officers the victim's identification. Mr. Sweet further stated the last dispatch given the victim was at 9:45 pm to 500 9th Ave. apt. #1. Victim allegedly never arrived at the above location as the dispatch was reassigned to another cab at 9:58 pm". The prevailing narrative is that the Zodiac Killer entered the taxicab somewhere by the intersection of Mason and Geary Streets in the theater district of San Francisco and then traveled to the Presidio Heights district. But Mason and Geary (or Union Square) is unlikely to be where Paul Stine was when he received the 9:45pm dispatch from LeRoy Sweet, asking him to pick up a fare from 500 9th Avenue.
The journey time from Mason and Geary (or Union Square) to 500 9th Avenue on a busy Saturday night is about 12 to 13 minutes. Therefore, if LeRoy Sweet knew that Paul Stine was in the vicinity of Mason and Geary or Union Square at 9:45pm when he gave him his second fare that night, he would have known that Paul Stine's journey time to 500 9th Avenue would have him arriving there at 9:58pm. So why did the police report state that another taxicab was allocated to that address at 9:58pm, when that was the time Paul Stine was expected at the address? Unless, of course, Paul Stine wasn't near the theater district when he received the 9:45pm dispatch - and the dispatch was given to him much closer to Washington and Cherry Streets, with the Zodiac Killer already seated in the taxicab. Paul Stine may have been already heading to Presidio Heights when he accepted the dispatch to 500 9th Avenue. One would assume that LeRoy Sweet knew exactly where Paul Stine was at 9:45pm because he expected Paul Stine to arrive at 500 9th Avenue earlier than 9:58pm. So when he didn't, LeRoy Sweet reassigned the dispatch to another taxicab.
If the expected time of arrival was 9:58pm from Mason and Geary Streets and the customer knew this, then there would have never have been any need for LeRoy Sweet to reassign another taxicab to the address that night. However, if Paul Stine arrived at Washington and Cherry two minutes after the 9:45pm dispatch, then he arrived at the murder scene at 9:47pm, eight minutes before the 9:55pm time of attack given in the police report (supposedly when the three teenagers first looked out of the window). If this was the case, then what was the Zodiac Killer doing in the taxicab for eight minutes? The further back towards Mason and Geary Streets (or Union Square) we take the taxicab when the 9:45pm dispatch was given by LeRoy Sweet, the less reason the customer has to become impatient and for another taxicab to be assigned to that address.
Paul Stine would likely have been traveling along Highway 101 from the San Francisco International Airport after his first fare was dropped off, and may have exited Highway 101 and Interstate 80 by 7th Street to pick up a random fare at the theater district - so the Zodiac Killer could have entered the taxicab anywhere in this locality. The taxicab meter reading taken at the crime scene supports the Zodiac Killer entering the taxicab in this area. However, when LeRoy Sweet gave Paul Stine the final dispatch, he was possibly much closer to Presidio Heights than once considered. Many will not like this analysis of a killer arriving at Washington and Cherry up to eight minutes prior to the 9:55pm attack time, because it doesn't conform to the widely held narrative of a taxicab driver being murdered the moment he parked up at the Washington and Cherry intersection. The statements of LeRoy Sweet may be erroneous, but they are what they are. Is it possible this extra time was swallowed up by something that occurred at the intersection of Washington and Maple Streets - the destination written in the taxicab trip sheet?
