Zimmerman was interviewed by Investigator D. Singleton and by Detective Chris Serino on the night of the shooting.[15][115] He also underwent voice stress analysis, a type of lie detector test, on the night of the shooting.[106] Crime Scene Tech D. Smith photographed his injuries and hands and collected gun shot residue. Zimmerman's clothes were taken as evidence after his wife arrived with a change of clothes.[116] The day after the shooting, Zimmerman performed a videotaped reenactment of the incident for police.[106]

Zimmerman was not given a drug or alcohol test.[18] Peter Bella, a retired Chicago Police forensic investigator, told The Washington Times, "Except for DUIs, police cannot test suspects for drugs or alcohol, unless the accused demands or consents to it, or they get a warrant".[117][118][119] The police did not suspect that Zimmerman was under the influence of drugs or alcohol, and he was never asked to take such a test.

The Martin family alleged that Seminole County Attorney Wolfinger met personally with Sanford Chief Lee on the night of the shooting and instructed Lee not to make an arrest. Based on their accusation, the Martin family requested that the Justice Department investigate the State prosecutor's office. Wolfinger responded that the accusations were "outright lies" and denied that any such meeting or communication took place. Wolfinger's office reported that the Sanford police consulted with Kelly Jo Hines, the prosecutor on call the night of the shooting, but it has not been disclosed what was talked about.[120]

On March 12, 2012, Police Chief Lee turned the investigation over to the State Attorney's office for review.[121] Lee said there was not enough evidence to arrest Zimmerman. "In this case Mr. Zimmerman has made the statement of self-defense," Lee said. "Until we can establish probable cause to dispute that, we don't have the grounds to arrest him." In response to criticisms of the investigation, Lee responded that "We are taking a beating over this" and defended the investigation.[122] "This is all very unsettling. I'm sure if George Zimmerman had the opportunity to relive Sunday, February 26, he'd probably do things differently. I'm sure Trayvon would, too."[71]

On March 13, 2012, Chris Serino sent a capias request to the state's attorney recommending charges of negligent manslaughter against Zimmerman, though Serino maintains he did not believe they had the evidence to support those charges and that manslaughter was only included in the capias in order for the prosecutor's office to continue with their own investigation.[123][124][125][126] The capias states, "the encounter between George Zimmerman and Trayvon Martin was ultimately avoidable by Zimmerman, if Zimmerman had remained in his vehicle and waited the arrival of law enforcement or conversely if he had identified himself to Martin as a concerned citizen and initiated dialog in an effort to dispel each party's concern". "There is no indication that Trayvon Martin was involved in any criminal activity at the time of the encounter."[127] The State Attorney's office initially determined there was insufficient evidence to charge Zimmerman and did not file charges based on the capias request.[126][128][129]

On March 16, Serino told the Orlando Sentinel that his investigation had turned up no reliable evidence that cast doubt on Zimmerman's account, that he had acted in self-defense. "The best evidence we have is the testimony of George Zimmerman, and he says the decedent was the primary aggressor in the whole event, everything I have is adding up to what he says."[130]
