After interviewing nearly three dozen people in the George Zimmerman murder case, the FBI found no evidence that racial bias was a motivating factor in the shooting of Trayvon Martin, records released Thursday show.

Even the lead detective in the case, Sanford Det. Chris Serino, told agents that he thought Zimmerman profiled Trayvon because of his attire and the circumstances — but not his race.

Serino saw Zimmerman as “having little hero complex, but not as a racist.”
