The attorney counseling George Zimmerman, who shot unarmed black teenager Trayvon Martin as he was walking home from the store with a bag of Skittles, says if charges are filed, Zimmerman will argue that he acted in self-defense and that Florida's stand-your-ground law applies.

Attorney Craig Sonner said the public is only hearing part of the story, and when all the facts come out, it will be clear that Zimmerman acted in self defense. A grand jury is scheduled to begin hearing the case April 10.

"George Zimmerman suffered a broken nose, and had an injury to the back of his head, he was attacked by Trayvon Martin on that evening," Sonner said. "This was a case of self defense."

When asked why Zimmerman went after Martin, even though a 911 dispatcher told him not to, Sonner said: "Those are questions that will be answered."

Sonner said the so-called stand-your-ground law, under which a person who feels threatened is not required to retreat and can "meet force with force" if attacked, will be applicable in the case.

Sonner insisted that Zimmerman is not a racist, pointing out that he and his wife mentored for two black children for free. READ MORE

A devastating storm system moved across the United States on Friday, spawning a slew of tornadoes that contributed to at least 28 fatalities in Indiana, Kentucky and Ohio.

National Weather Service meteorologist John Gordon reported Friday afternoon the agency had about "half a dozen reports of tornadoes on the ground," as well as reports of "significant damage" -- making his comments before some of the worst twisters were reported.

"This is an enormous outbreak that's going on right now across Kentucky and the South," Gordon said. "It's crazy. It's just nuts right here."

Southern Indiana was particularly hard hit, with Indiana Department of Homeland Security spokesman John Erickson saying three had died in Jefferson County as a result. Sgt. Rod Russell with the Indiana State Police said later that three people also were killed in Scott County.

In addition, Emergency Management Director Leslie Cavanaugh of Clark County -- which has about 110,000 people -- reported one death. Sheriff's Department Maj. Chuck Adams added that a man was found dead in his car several miles outside Henryville.

"We've got total devastation in the north-ceindntral part of the county (and) widespread damage from the west to the east," added Adams. "We are inundated with calls."

At least 15 people were killed across Indiana, authorities said.

Aerial footage from CNN affiliate WLKY showed structures torn to shreds and large swaths of trees knocked down in Henryville, about 20 miles north of Louisville, Kentucky.

Other aerial images showed similar devastation in St. Paul, Indiana. Several officials -- including Jeffersonville, Indiana, Mayor Mike Moore, U.S. Sen. Dan Coats and Adams -- indicated that the town of Marysville suffered especially significant damage.

Cavanaugh also said that the local high school, Henryville Junior-Senior High School, had been "demolished."

According to Sara Reschar, an administrative assistant for the West Clark Community Schools, "students were already out of the school when the storm hit" -- having been dismissed about 15 minutes earlier. Adams said there were some "scrapes and scratches," but no serious injuries as a result.

Authorities used thermal imaging equipment, search dogs and other means Friday night to look for a 9-year-old boy in Henryville whose whereabouts was unknown after the tornadoes came through, Adams said.
