A funeral director analyzing Trayvon Martin’s body said there were no signs of a violent struggle, NY Daily News reported.

The director, Richard Kurtz, told CBS News there were no bruises, cuts or scrapes indicative of a fight between Martin and George Zimmerman, the man accused of pulling the trigger.

Kurtz’s claims contradict the story Zimmerman told about being attacked by Martin for several minutes before he shot the 17-year-old in self-defense. Zimmerman said Martin had smashed his head into the pavement and punched him.

An approximately-5,000-strong demonstration in solidarity with Martin marched from Northrop Mall through Dinkytown and the Stadium Village Thursday evening. Protesters chanted and donned hooded sweatshirts.
