The lead homicide investigator on the Trayvon Martin case recommended that George Zimmerman be charged with manslaughter only to be denied, according to ABC News.

Chris Serino, the Sanford, Florida investigator, filed an affidavit on the night of crime saying he was unconvinced of Zimmerman's account. However, the state attorney's office Norman Wolfinger told Serino not to press charges against Zimmerman after he said there wasn't enough evidence against him.

Police later accepted Zimmerman's claim that he shot the 17-year-old Martin out of self-defense.

The state attorney's office said "no comment" when asked about Serino's affidavit.
