Last month, Shellie Zimmerman, 26, pleaded guilty to a misdemeanor perjury charge for lying about the couple's finances during a bail hearing following her husband's arrest after Martin's shooting.

George Zimmerman, 29, said he acted in self-defense when he killed Martin and the polarizing case opened up national discussions on self-defense laws and race. Martin was black. Zimmerman has a white father and Hispanic mother.

Shellie Zimmerman was sentenced to a year's probation and 100 hours of community service. Her husband did not attend the sentencing hearing in the Sanford courtroom.

Zimmerman has been involved with a domestic case at least once before. In 2005, Zimmerman's former fiancee filed for a restraining order against Zimmerman, alleging domestic violence. Zimmerman responded by requesting a restraining order against his then-fiancee.

Since his acquittal, Zimmerman has gotten a speeding ticket in Florida and was pulled over on suspicion of speeding on a highway near Dallas but not ticketed.

Forney police stopped Zimmerman as he drove west on U.S. 80, about 20 miles east of Dallas. A police dashcam video released July 31 shows an officer interacting with Zimmerman and letting him go with a warning.

The officer can be heard saying, "Just take it easy. Go ahead and shut your glove compartment. Don't play with your firearm."

Although the officer's comments indicated Zimmerman had a gun, a weapon can't be seen and it's not clear that he had one. However, Zimmerman had a concealed weapons permit in Florida that would be also recognized under Texas law. The gun used in Martin's shooting remains in the custody of the federal government, which is looking into a possible civil rights case.
