More details on the Zimmerman case. Much of it is what I’ve already told you. Precisely that Martin came up on Zimmerman and punched him in the face, then got on top of him. The rest?

“As has been reported, Zimmerman told police officials that he lost sight of Martin and went around a townhouse to see where he was. Then he claimed Martin confronted him and punched him, knocking him down.

According to The Daily Beast’s source, Zimmerman told police that when he was on the ground, Martin straddled him, striking him, and then tried to smother him.

Zimmerman claimed that he yelled for help, and that various neighbors who peered out to see the fight from their backyards didn’t get involved. Zimmerman, the source said, told officers he was so paralyzed by fear that he initially forgot he had a gun, but he said that after Martin noticed his 9mm pistol, Zimmerman pulled it out of his belt holder and fired one round, a hollow-point—the round that killed Martin. (The autopsy report on Martin has not yet been released.)

According to the source, Zimmerman told police that Martin’s last words after the shooting were, “Okay, you got it.” He said the phrase twice, then turned and fell face-down on the ground.

(Martin’s father told reporters last month that police had told him his son’s last words were, “You got me.” Benjamin Crump, the family’s lawyer, said he doesn’t believe either account.)

According to the source, Zimmerman told police he didn’t realize that Martin was seriously injured, and that he lunged to get on top of him after the teenager fell to the ground. Moments later, a police officer from Sanford arrived, placed him in handcuffs and took his gun.

The law-enforcement source said Sanford police investigators interviewed Zimmerman three times about the shooting. The last time followed a walk-through of the shooting site. Afterward, three detectives grilled Zimmerman at police headquarters in their most thorough and hostile questioning, according to the source. They told Zimmerman they didn’t believe him, the source said, and tried to poke holes in his story.

A spokesman for the Sanford Police Department declined to comment on the case.

The precise details of that story are crucial to the case against Zimmerman. Perhaps the key issue will be who instigated the confrontation. The brief affidavit filed by the special prosecutor in support of the murder charge contends that Zimmerman provoked the encounter by following and confronting the teenager.

Then there are the dramatic cries for help heard on the 911 call during the struggle. Martin’s mother said it was her son’s voice, and the special prosecutor in the case agrees. But Zimmerman’s supporters argue that the pleas came from him.

Of course as I pointed out here, when a Sanford Police detective initially played the 911 tape for Martin’s father he said that the voice wasn’t his son’s. He only changed that story afterwards, possibly on the advice of their lawyers.

Nevertheless the really interesting thing we learn in this story is that Angela Corey considered none of this evidence, didn’t even consider it, in spite of three witnesss, one who is the only eye-witness of the events before Martin was shot. This witness stated abolutely that it was Martin on top of Zimmerman and that it was Zimmerman calling for help.
