The lead homicide investigator in the shooting of unarmed teenager Trayvon Martin recommended that neighborhood watch captain George Zimmerman be charged with manslaughter the night of the shooting,multiple sources told ABC News.

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.

One complicating factor in the investigation was that the first detective to interview Zimmerman about the shooting was a narcotics officer rather than a homicide detective.

Since there was clearly a death involved, why did a narcotics officer have the priority in questioning Zimmerman?
The shooting and the circumstances and not drugs should have been the focus. If they knew the questioning would screw up the investigation, and they should have known, it should have been done later.
