Martin Protest

A witness to the fight between George Zimmerman and Trayvon Martin moments before the 17-year-old was killed testified Friday at Zimmerman’s murder trial that from his vantage point Trayvon was on top of the 29-year-old volunteer watchman.

Jonathan Good, the witness, testified in a Florida courtroom Friday that he could not see whether Trayvon was punching Zimmerman during the fight, contradicting earlier police statements he made.

Zimmerman is facing second-degree murder charges in the killing of Martin. He claims he killed the teen in self-defense, while state prosecutors say Zimmerman is a murderer.

Good testified that he heard a commotion on the night of Feb. 26, 2012, and stepped outside his house to see what was going on. That’s when he said he saw Zimmerman and Martin fighting.

In his initial statements to police, Good said Zimmerman was on the ground and getting hit shortly before Martin was killed. He later clarified his statements to say he did not see any blows coming from Martin.

Good denied that he lied to cops when he changed his statements after being asked about the contradictions by Zimmerman defense attorney Mark O’Mara.

Good is the second prosecution witness to testify in the Zimmerman trial. His testimony was proceeded by Rachel Jeantel, a friend of Martin who was the last person to speak to the teen before his death.

The Zimmerman case has gained national attention due to race and the fact that Martin, who was black, was unarmed when Zimmerman, who is half white and half Hispanic, shot him.

The case adjourned for lunch at 11:30 a.m. EDT. The Zimmerman trial is scheduled to resume at 1 p.m. EDT.
