Sanford, Florida (CNN) -- An affidavit of probable cause in Florida's case against George Zimmerman for the shooting death of an unarmed 17-year-old says that the neighborhood watch volunteer "profiled" the victim, Trayvon Martin, and disregarded a police dispatcher's request that he await the arrival of police. The affidavit, which was drawn up Wednesday but not made public until Thursday, was prepared by investigators for the state attorney, who charged Zimmerman with second-degree murder Wednesday. Public documents in the Trayvon Martin shooting Zimmerman's relatives say that he did not profile Martin and that he shot him in self-defense. They say Zimmerman killed Martin after the teen punched him and slammed his head on the sidewalk.

"Martin was unarmed and was not committing a crime," affidavit says
@placeholder spoke to the dispatcher and asked for an officer to respond because Zimmerman perceived that Martin was acting suspicious.
"The witness advised that @placeholder was scared because he was being followed through the complex by an unknown male and didn't know why.
"The 'accident' I was referring to was the fact that @placeholder and my son ever crossed paths.
