The above is listed in the police report concerning the murder of Paul Stine on October 11th 1969, but something isn't quite right with these statements. The last dispatch given to Paul Stine was supposedly in the area of Union Square, San Francisco at 9.45 pm.
Leroy Sweet, fully aware it was a busy Saturday night deployed Paul Stine to a regular pick up at 500 9th Avenue. This is a minimum journey time of 18 minutes from Union Square, to which Paul Stine should have arrived at 10.03 pm, yet Leroy Sweet had already reassigned another taxicab to 500 9th Avenue at 9.58 pm, after only 13 minutes, so why the impatience.
The time of the attack was marked at approximately 9.55 pm, with the radio dispatch to police officers issued at 9.58 pm. This on the face of it ties perfectly with the statement of Zodiac, who stated in the November 9th 1969 'Bus Bomb' letter "2 cops pulled a goof about 3 min after I left the cab." Donald Fouke and Eric Zelms received the dispatch at 9.58 pm traveling northbound on Presidio Avenue, having just passed Washington Street. The journey time to the intersection of Jackson and Maple where he they spotted the 'lumbering man', is just shy of one minute, placing them there at 9.59 pm. We know the journey time from the taxicab to the intersection of Jackson and Maple is 3 minutes walking time, validating that the Zodiac Killer left the taxicab at 9.56 pm. The attack on Paul Stine was observed by the three teenagers at 9.55 pm, with the Zodiac leaving one minute later.
We do not know exactly how long the taxicab was sitting at the Washington and Cherry intersection before the teenagers set eyes on it, however we know that the Zodiac had already exited the rear of the taxicab to enter the front passenger seat. The taxicab may have arrived slightly earlier than 9.55 pm, but for the sake of argument we will leave the time at 9.55 pm. This would mean that had Paul Stine received a dispatch from Leroy Sweet at 9.45 pm, the journey time took 10 minutes from Union Square, possibly as low as 9 minutes, when the journey time should have took a minimum of 12-13 minutes. This could have Paul Stine leaving Union Square at 9.42-9.43 pm, instead of 9.45 pm. The margins are small and may seem inconsequential. However, if Paul Stine had departed Union Square at 9.45 pm, a journey time of 18 minutes to 500 9th Avenue would be 10.03 pm, at which point Leroy Sweet had already allocated another taxicab for the fare up to five minutes earlier. His impatience in removing Paul Stine from the scheduled pick up seems unwarranted, unless of course the time delay was considerably longer.
The return journey to Union Square is approximately 21 minutes, bringing Paul Stine back to the theater district at 9.31 pm, fourteen minutes earlier than the final dispatch by Leroy Sweet of 9.45 pm. It is unlikely he arrived back quite this early, but 9.45 pm, allowing for Paul Stine to pick up Zodiac, in an unscheduled stop, fill out his trip sheet and arrive at Washington and Cherry in 9-10 minutes is not likely.
The Harvey Hines report, secured by Alex Lewis, seems to suggest that the Zodiac Killer ordered a taxicab from a public payphone at Union Square near to the St. Francis Hotel on the night of October 11th 1969. It stated "In looking at an area map of San Francisco, I found 217 Eddy Street appeared to only be two to three blocks from where Paul Stine picked up the Zodiac on October 11, 1969. I then called Inspector Dave Toschi at the SFPD and got more details on the Stine Killing. Toschi said that they had determined that the killer had called for a cab using the public payphone located at Union Square. Toschi said the cab then picked the killer up and drove to the corner of Washington and Cherry Streets."
If the killer had entered the taxicab, say 9.42 pm, then Paul Stine would be three minutes en route, with the Zodiac Killer already in tow, heading toward Washington and Cherry when he received the dispatch from Leroy Sweet at 9.45 pm. This now gives Paul Stine enough time to reach Washington and Cherry by 9.54-9.55 pm. In other words the dispatch by Leroy Sweet was issued to Paul Stine close to the theater district, but not in it.
There appeared only one reason for Leroy Sweet to reallocate a second taxicab at 9.58 pm to 500 9th Avenue, after just 13 minutes, for a 18 minute journey. The reason was not likely impatience, but the fact he was likely informed of the regrettable events at Washington and Cherry almost immediately, so the police could learn where the passenger entered the taxicab, along with any associated details, and sadly for him was compelled to send an alternative taxicab. Using the 9.45 pm dispatch time by Leroy Sweet, allied with the taxicab meter reading, it is highly likely the Zodiac Killer entered the taxicab of Paul Stine in the theater district of San Francisco, but not after 9.45 pm, and not en route. He was already firmly seated in the back of Paul Stine's taxicab, away from Union Square.
