Prosecutors are expected to wrap up their case Friday in the murder trial of George Zimmerman, with Trayvon Martins mother likely to be the states final witness.
On Wednesday, before a holiday break, jurors heard about Zimmermans criminal-justice studies and his interest in police work, as well as testimony from forensic experts.
Zimmerman, 29, is charged with second-degree murder in the Feb. 26, 2012, shooting death of Trayvon, 17, of Miami Gardens. Zimmerman claims self-defense, saying he was attacked by Trayvon in the gated Sanford community where Zimmerman lives and where Trayvon was visiting his father.
Part of the states theory in the case is that Zimmerman, a neighborhood-watch leader, acted as a vigilante and wannabe cop, profiling and pursuing an unarmed Trayvon.
Seminole Circuit Judge Debra Nelson cited that theory in allowing the state to call witnesses and present other evidence Wednesday that documented Zimmermans previous interest in legal issues and law enforcement.
Zimmerman was one of the better students in a criminal-litigation course, the professor, U.S. Army Capt. Alexis Carter, said. He earned an A in the 2011 class, which the instructor said covered on several occasions Floridas controversial Stand Your Ground law.
In an interview televised last year and played in court this week, Zimmerman said he had never heard of Stand Your Ground until after the shooting.
Defense attorney Don West took his cross-examination of Carter as an opportunity to have the witness explain elements of self-defense. Carter testified that injuries do not have to be life-threatening or even present to make a reasonable claim of self-defense.
You dont have to wait until youre almost dead before you can defend yourself? West asked.
No. I would not advise to do that, Carter replied.
Technical problems slightly delayed the testimony of another of Zimmermans Seminole State College professors. Gordon Scott Pleasants connected to the courtroom via Skype, but his screen quickly became inundated with call-in requests from pranksters who had been following the trial on TV.
There is now a really good chance that we are being toyed with, defense attorney Mark OMara said. They moved the interview from Skype to an iPhone projected into a microphone on the witness stand.
Prosecutors also called witnesses who confirmed that Zimmerman applied in 2009 for a job with the Prince William County, Va., police department. His application was rejected because of poor financial credit, Lt. Scott Kearns testified
And in 2010, Zimmerman requested to go on a ride-along with Sanford Police. He wrote on his request form that the experience would help solidify my chances of a career in law enforcement, said Jim Krzenski, a Sanford Police administrator.
Jurors ended the day with testimony from two Florida Department of Law Enforcement analysts.
Amy Siewert explained how Zimmermans semiautomatic pistol functioned. She testified that the single shot that killed Trayvon was a contact shot, meaning the muzzle of the gun was in contact with Trayvons hooded sweatshirt when it fired.
On cross-examination, Siewert said she could confirm that the gun was touching Trayvons hoodie, not that it was pressing against it, as prosecutor John Guy noted in his opening argument.
Anthony Gorgone, a state DNA specialist, gave a detailed rundown of the stains and other evidence he examined. His testimony took up most of the afternoon, and was often full of technical specifics, but jurors appeared to remain engaged in what he had to say.
Trayvons DNA was not on the grip of Zimmermans pistol, nor was Zimmermans DNA found under the teens fingernails.
A witness testified Tuesday that Zimmerman told him Trayvons hands touched the weapon. Gorgone noted that not all contact leaves behind DNA residue, and that weather could affect DNA preservation.
West spent part of his cross-examination asking Gorgone about how the DNA samples were packaged and handled. Gorgone testified that wet items should be left to dry or breathe before being processed for DNA. Trayvons hoodie and an inner sweatshirt he was wearing were packaged in plastic bags, leaving them with a moldy odor, he said.
The trial will resume Friday morning in a fifth-floor courtroom in Seminole County. Nelson indicated in court on Wednesday that the state will rest its case this week, and the defense will begin putting on its side. Zimmerman faces up to life in prison if convicted of second-degree murder.
As the state winds down its case against Zimmerman, community groups in South Florida are starting to prepare for possible reactions to the trial's verdict. The Miami-Dade County Community Relations Board and the Miami-Dade Youth Commission are hosting a meeting from 6 to 8 p.m. on Tuesday at the North Dade Regional Library to discuss activities being planned around the county before and after the verdict. They already have encouraged people to tweet with the hashtag #keepcalmfortrayvon.
The 44 days between Trayvon's death and Zimmermans arrest sparked racial protests and marches; the case also led to debate about Floridas controversial Stand Your Ground law.
