Trayvon Martin had THC in his system the night George Zimmerman shot him

ABC News buried that detail in the last paragraph of the second page of a story on their website. Also, Trayvon Martin's father told police the man screaming for help on tape was not his son. We have previously learned George Zimmerman was severely beaten up. Why is he being prosecuted?

Via ABC News:

Two police reports written the night that George Zimmerman shot Trayvon Martin said that Zimmerman had a bloody face and nose, according to police reports made public today.

The reports also note that two witness accounts appear to back up Zimmerman's version of what happened when they describe a man on his back with another person wearing a hoodie straddling him and throwing punches.

It has been such a contentious case that even the evidence is being disputed.

The police report states that Trayvon Martin's father told an investigator after listening to 911 tapes that captured a man's voice frantically callling for help that it was not his son calling for help[...]

The teen, who lived in Miami, was in Sanford while serving a suspension for a bag of marijuana being discovered in his possession. Martin had THC, the drug found in marijuana, in his blood on the night of his death, according to the autopsy. His family told ABC News that it was "trace amounts" of THC.
