But Sanford, Fla., Investigator Chris Serino was instructed to not press charges against Zimmerman because the state attorney's office headed by Norman Wolfinger determined there wasn't enough evidence to lead to a conviction, the sources told ABC News.
Police brought Zimmerman into the station for questioning for a few hours on the night of the shooting, said Zimmerman's attorney, despite his request for medical attention first. Ultimately they had to accept Zimmerman's claim of self defense. He was never charged with a crime.
Serino filed an affidavit on Feb. 26, the night that Martin was shot and killed by Zimmerman, that stated he was unconvinced Zimmerman's version of events.
