In summary; Time of attack recorded as 9.55 pm. Both officers receive the initial broadcast at 9.58 pm.
Zodiac leaves crime scene at
9.56 pm, arrives near corner of Jackson and Maple at
9.59 pm. It is a 3 minute walk.
Donald Fouke responds from Presidio Avenue/Washington St
9.58 pm. It takes 1 minute to arrive at Jackson and Maple.
Time now
9.59 pm. Zodiac and Donald Fouke cross paths.
Zodiac directs Donald Fouke towards Arguello. Time now approximately
9.59:30 pm.
Donald Fouke heads up to Arguello. Receives update to WMA at
10.00 pm. Thinks crikey, that may be the man I just spoke to heading up Maple towards the Presidio, where
HE stated he last saw him going.
Donald Fouke heads into West Pacific Avenue to Julius Khan playground for a cursory search. Time now
10.01 pm.
Donald Fouke finds nothing, heads back to Cherry. Time now
10.02 pm.
Armond Pelissetti receives the initial broadcast at
9.58 pm. Arrives at crime scene
9.58:30 pm.
Armond Pelissetti ushers the kids, checks on Stine, gets the amended description and rushes to radio to update to WMA. This takes 90 secs approximately. So Armond Pelissetti gives the update to WMA at
10.00 pm.
Up above we stated Donald Fouke received this update at
10.00 pm, this tallies perfectly with Armond Pelissetti.
Cherry Street takes 1 minute to walk, but Armond Pelissetti is checking alcoves and parked cars so "he doesn't get his head blown off." So he goes half the speed and arrives at the top of Cherry at
10.02 pm. Exactly the time above that Donald Fouke arrived after his search for the man at Julius Khan playground. Donald Fouke and Armond Pelissetti are now at the top of Cherry at
10.02 pm.
Zodiac is not a fool though, he knows Donald Fouke last saw him heading into Maple at approx
9.59:30 pm. So he re-enters Jackson Street and heads to Spruce Street, arriving at
10.01:30 pm. It takes 2 minutes to walk this block. Donald Fouke saw and spoke to him by
9.59:30 pm, thus explaining what time he arrives at Spruce.
Neighbors near Spruce are alerted to Donald Fouke's patrol car siren arriving at Julius Khan playground at
10.01 pm (time stated above), so look out of their windows.
Seconds later after Donald Fouke has finished his cursory search by Julius Khan playground, he leaves.
Zodiac enters the park hastily, seen by these neighbors, who are still nosing out of their windows and reported as such here. The timeline fits perfectly.
This is why the man Donald Fouke stopped had to be Zodiac. Because Donald Fouke saw only one person, not two, and the description given by Donald Fouke virtually matched the teenagers, and Zodiac is the only person to have any reason to direct Donald Fouke away from the crime scene, which he did.
