All of the timestamps that follow are, I believe, accurate to within 1 second. Listen to the recording of Zimmerman's call to police, and then feel free to challenge any of the timestamps I've come up with.
Starting at 7:11:40 PM, Trayvon starts running. This is the 00:00 point where the timeline evidence becomes critical.
The dispatcher says "he's running, which way is he running"?
At 7:11:44 PM (00:04 seconds in), Zimmerman's car door opens, indicated by a door chime heard on the recording.
At 7:11:45 PM (00:05), Zimmerman begins saying "Down by the other entrance".
Here's where we need to ask an important question: How does Zimmerman know Trayvon is running toward the other entrance? If you look at the map of the Retreat at Twin Lakes, the other entrance is at the South end of the townhome complex. Zimmerman, still in his truck, is well over 500 feet and North of the South entrance and cannot see the South entrance. The only logical conclusion we can make is that Trayvon had to have disappeared behind 1211 Twin Trees Lane - or Trayvon was running in such a way that it was obvious he was about to disappear behind 1211 Twin Trees Lane. Other evidence confirms Trayvon did indeed run behind the row of townhomes, so there should be no dispute regarding the direction he ran.
At 7:11:47 PM (00:07), Zimmerman's car door is shut, indicated by a thump that no one disagrees is a car door closing. Now we know Zimmerman has exited his vehicle. If Trayvon has already disappeared behind 1211 Twin Trees Lane, then he has no idea Zimmerman is out of the vehicle. More importantly, even if Zimmerman was chasing after Trayvon, Trayvon wouldn't know it. The narrative that Zimmerman chased Trayvon is key in believing Zimmerman to be guilty. But did he really chase him? Did he even really follow him? If we pay attention to the evidence, the answers are not very difficult.
At this point (still at 00:07), the 2nd timeline perspective becomes relevant. According to Trayvon Martin's phone records, his call with Rachel Jeantel disconnected at 7:11:47 PM. Rachel Jeantel stated she heard wind noise from Trayvon's phone and the phone soon disconnected. Rachel reconnected to Trayvon 19 seconds later (again according to Trayvon's phone records). If you think I'm making these times up, search out the trial video where a T-Mobile manager, Raymond MacDonald, testified and confirmed the timestamps shown in State's exhibit 166 (Zimmerman's phone record) and 167 (Trayvon's phone record). Mr. MacDonald testified the time durations on Trayvon's phone records were shown to the nearest hundredth of a minute.
At 7:11:53 PM (00:13 seconds in), the first wind noise can be heard in Zimmerman's phone. If the wind noise is what later gave Zimmerman away to the dispatcher, prompting to ask if he was following Trayvon, then we can only reasonably infer the wind noise beginning at 00:13 is when Zimmerman first began following (on foot) in the same direction Trayvon had first run. That Zimmerman may have lost sight of Trayvon at the 00:05 mark - or possibly even sooner and then waited until 00:13 before he started running, this dilutes the chase theory, if not completely negating it. What happens further down the timeline will completely negate the chase theory.
At only 12 seconds in (and no wind noise yet in Zimmerman's phone), and if Trayvon was at the rear corner of 1211 Twin Trees Lane at the 00:05 mark, then we can reasonably guess where Trayvon was at the 00:12 mark. If Trayvon was running relatively slowly, say he was averaging 10ft per second, then he would be 70 feet South of the rear corner of 1211 Twin Trees Lane while Zimmerman had not yet started running. The distance between the two of them could be as much as 220 feet (150 feet between Zimmerman's truck and the rear corner of the building + the 70 feet South). Let's not give Zimmerman the benefit of any doubt and say Trayvon did not reach the rear corner of 1211 Twin Trees Lane until the 00:10 mark. I am being more than reasonable in extending the time this far. In this scenario, and Trayvon still only averaging 10ft per second, he would be 20 feet South of the rear corner of 1211 Twin Trees Lane, and as much as 170 feet away from Zimmerman before Zimmerman started running. You can do the math in either scenario if Trayvon was running closer to full speed, say around 20ft per second. Again, I am being reasonable and not giving Zimmerman any benefit of doubt by my using the example that Trayvon was running slowly. The farther away Trayvon was from Zimmerman, the less it looks like a chase, no?
Do you now see how Zimmerman almost positively lost sight of Trayvon before he followed in the same direction? Do you also see understanding this evidence paints a very different picture than the one most people believe? Do you also realize Zimmerman, in real time at only 12 seconds in, has no idea he will ever lay eyes on Trayvon again?
What happens over the next 108 seconds also confirms Zimmerman has no idea he will ever lay eyes on Trayvon again. It also completely negates any chase theory, and it completely negates the fabrication that Zimmerman followed Trayvon even after being told "we don't need you to do that". We get to hear all of it and can replay the recording to our hearts content. If you disagree with me, are you willing to listen to the recording and then state why you disagree?
Getting back to the critical part of the timeline -
At 7:11:56 PM (00:16), the dispatcher asks "Are you following him?".
At 7:11:59 PM (00:19), Zimmerman says "Yeah".
At 7:12:00 PM (00:20), the dispatcher says "We don't need you to do that".
At 7:12:02 PM (00:22), Zimmerman says "OKay".
At 7:12:11 PM (00:31), Zimmarman says "He ran" as if to say "he ran away" or "he ran off". There is no indication Zimmerman knows where Trayvon is, and this will not change for the remaining minute and a half of the recorded phone call.
Going back to the 2nd timeline perspective -
At 7:12:06 PM (00:26), Rachel Jeantel reconnects with Trayvon (again, according to Trayvon's phone records). According to her statements, she says she still heard wind noise in Trayvon's phone, indicating Trayvon was still running. If Trayvon was running for all of those 26 seconds (and the evidence indicates he was), at 10ft per second, then he would have run 260 feet. Even when using the example where Trayvon was at the rear corner of 1211 Twin Trees Lane at the 00:10 mark (instead of the 00:05 mark), Trayvon would have to be 160 feet South of the corner of the building at the 00:26 mark. This would be 130 feet South of the spot of the shooting. If he was running more like 20ft per second, then he would have run 520 feet and could have literally been at the back door of the house he was staying at (and more than 300 feet South of the spot of the shooting). Upon reconnecting, Rachel Jeantel asked Trayvon where he was, and Trayvon replied "I'm in the back behind my daddy's fiance's house. I lost him". Interesting, is it not?
So, it seems neither Zimmerman or Trayvon knew where the other was. We know the address Trayvon was staying at was 2631 Retreat View Circle and that the home was three addresses North of the South entrance, some 300 feet from the spot of the shooting.
From just the first 30 seconds or so, starting at 00:00, why do people believe Zimmerman chased anyone? If we continue down the timeline beyond these 30 seconds, the only thing we will determine is that Zimmerman continued speaking with the dispatcher for another 90 seconds. And it is clear he has no idea where Trayvon is. Rachel Jeantel is unable (or unwilling) to describe what happened during those same 90 seconds. An additional 120 seconds goes by, and neither Rachel Jeantel or Zimmerman is able (or willing) to adequately describe what occurred during all of those 120 seconds. Rachel Jeantel claims a hard breathing man came up to Trayvon and said "what are you doing around here"? And then she heard a thump and "wet grass sounds" and then the phone disconnected for the last time. This disconnect time was 7:15:43 PM or 4 minutes and 3 seconds after Trayvon started running. Do you see that Zimmerman and Trayvon had no direct interaction for nearly 4 full minutes?
Three different ear witnesses, including Jenna Lauer, described a commotion that began immediately North of 1211 Twin Trees Lane, and 28 seconds after Rachel Jeantel's phone call disconnected, the first 911 call came in, 44 seconds before the gunshot. That caller was Jenna Lauer, and she lived at 1211 Twin Trees Lane (the very address that is at the Northern most spot of the area we are talking about). No other call to 911 came in before the gunshot. There is no physical evidence South of the spot of the shooting. So I ask again, how and why did Trayvon Martin run South of the spot of the shooting and then 4 minutes later return to the spot of the shooting? Given all the other evidence, what could Zimmerman possibly have done to force or even partially persuade Trayvon to return to the North end? If there is nothing to latch on to, then Trayvon had to have voluntarily returned to the North end? Why?
Finally, the gunshot occurred at 7:16:55 PM. As Rachel Jeantel's phone call ended at 7:15:43 PM, and we get to hear a man screaming for help for 44 seconds prior to the gunshot, this indicates the physical altercation lasted at least 72 seconds. What evidence is there the screams for help came from Trayvon? Given the totality of evidence, the only reasonable conclusion that can be made is that Zimmerman was the one screaming for help. If I'm wrong, please show me. I invite opposing viewpoints.
There was a fight that lasted at least 72 seconds, Zimmerman screamed for help for much of this time, an eye-witness saw the fight before the gunshot and saw Trayvon on top of Zimmerman, and Trayvon never acknowledged the witness or stopped fighting (or stopped doing whatever it was that was causing Zimmerman to continue screaming for help), and somehow people have no understanding of this evidence and don't want to. In fact, they won't even discuss it. Who is reasonable and who isn't?
