The fifth witness of Wednesday, Seminole State College Professor Scott Pleasants, testified via Skype. Dozens of people started trying to call Pleasants on Skype, forcing him to testify via phone instead.

Defense attorney and former Local 6 legal analyst Mark O'Mara questioned Pleasants about if Zimmerman read the book or discussed portions of it online. Pleasants said he can't confirm if Zimmerman participated in online discussions or read the book.

Pleasants testified Zimmerman posted to him on June 23, 2011 that his goal was to become an attorney and eventually a prosecutor, battling the state trying to show Zimmerman as a "wannabe cop."

The state also called as their 34th witness Amy Siewert, forensic technologist and Florida Department of Law Enforcement firearms analyst. Siewert showed jurors how Zimmerman's KelTec 9 semiautomatic gun works.

Siewert testified Zimmerman had a magazine full of 6 rounds, plus one in the chamber, meaning he had removed magazine and inserted round after one already in chamber. Prosecutor John Guy asked Siewert about the powder that comes from the gun after being fired and how the particles can leave a pattern on an object. Siewert said gas and particles can leave remnants on clothing and body called stippling.

The state then brought out Martin's clothing and had Siewart show how she found gunpowder on Martin's hooded sweatshirt during her analysis. Siewert said patterns of residue vary based on distance and other factors. Siewert said the hooded sweatshirt is consistent with contact shot, fire up against the hooded sweatshirt.

Siewert also said Martin's sweatshirt beneath the hoodie has the bullet hole that lines up with the hoodie. The sweatshirt also shows signs consistent with contact shot, Siewert said, adding that the sweatshirt is consistent with muzzle of gun touching outer hoodie and the garment being in contact with inner sweatshirt.

O'Mara then questioned Siewert about Zimmerman's gun, comparing it to a single-action gun. Siewert called Zimmerman's gun "safe in terms of it will not fire unless the trigger is pulled."

Siewert said the gun was "touching" garment and did not say it was pressed against Martin's chest. The state had previously told jurors the gun was "pressed" against Martin's chest. She didn't determine an exact distance between the gun and Martin's chest.

During redirect, prosecutor John Guy asked Siewert if a firearm could be used for other purposes.

The first witness called on Wednesday was Seminole State College registrar Sonja Boles-Melvin who had Zimmerman's college records. Records show Zimmerman applied for criminal justice degree in 2010/2011 anticipating graduation in spring 2012.

The state then called Lt. Scott Kearns of Prince William County Police--where Zimmerman applied to be a police officer. Nelson allowed testimony from Kearns at the hearing earlier Wednesday.

Kearns then testified Zimmerman's actual police application was destroyed on July 8, 2012. Zimmerman's rejection letter was dated July 8, 2009 and Kearns said he had no record of a sinister reason his job was denied.

Kearns said the reason Zimmerman's application was rejected was because of bad credit.

Earlier Wednesday, the defense voiced a desire to introduce 17-year-old Trayvon Martin's past because of Zimmerman's school records being allowed in the trial  Nelson said she disagreed and that the issues are not related. Nelson told defense any attempt to interject Martin's fight history is an "argument for another day."

Zimmerman, a former neighborhood watch volunteer, has pleaded not guilty to second-degree murder. He says he shot Martin, an unarmed black teenager, in self-defense.
