The lawyers for Trayvon Martin's family want the US Justice Dept. to investigate the state attorney's office with relation to the case.

Attorneys sent a letter the Dept. of Justice asking for an investigation into the actions of the state attorney's office the night Trayvon Martin was shot and killed by George Zimmerman, who claimed self-defense for the shooting.

The letter says that on the night of the shooting, State Attorney Norm Wolfinger and Sanford Police Chief Bill Lee met and chose to overrule the lead homicide investigator, who said that Zimmerman should be arrested for manslaughter.

The letter claims the investigator filed an affidavit saying that he did not find Zimmerman's statements regarding the shooting to be credible. The letter also says that Zimmerman's family members were present at the police department when Wolfinger and Lee met regarding the case.

The attorneys want to know why Wolfinger and Lee made that decision.

Sanford Police Dept. has said that the state attorney's office told them they could not arrest Zimmerman because of his self-defense claims based on Florida's Stand Your Ground law.

State Attorney Norm Wolfinger issued the following statement in response to the letter:

"I am outraged by the outright lies contained in the letter by Benjamin Crump to Deputy Assistant Attorney General Roy Austin dated April 2, 2012.  I encourage the Justice Department to investigate and document that no such meeting or communication occurred. I have been encouraging those spreading the irresponsible rhetoric to stop and allow State Attorney Angela Corey to complete her work.  Another falsehood distributed to the media does nothing to forward that process."
