Trayvon Martin's parents are reacting to what they believe is a new low from George Zimmerman's defense team.

Mark O'Mara told WFTV he's digging into Martin's past, including any information from social media accounts like Facebook and Twitter. It's a move that's causing controversy.

Martin has virtually disappeared from the Internet. There are no active Facebook accounts or Twitter feeds associated with him to access.

"We have not been able to find accounts that we know were there or that we have anecdotal evidence that they existed at one point, which means they were there and now they are not," said O'Mara. "In a case like this, we have to look and see what might be there to determine if it's truly relevant information."

The state responded, calling the motion a fishing exhibition. Zimmerman's attorney told WFTV he's just looking for anything relevant to the case.

But that's not stopping O'Mara, who has filed paperwork requesting copies of school records, copies of cellphone usage, and any social media activity.

"We know we have to look like a doctor looking for X-rays at lab results. Until we get the information we don't know what to do with it," said O'Mara.

The Martin family responded and sent WFTV the following statement:

"Trayvon's parents maintain that his school records and Facebook page are completely irrelevant to George Zimmerman's decision to get out of his car to profile, pursue, and shoot their son in the heart on February 26, 2012. How does George Zimmerman's review of Trayvon Martin's high school and middle school records and Facebook page bear any relevance to Zimmerman's decision to pull the trigger and kill a seventeen year old child? Is this going to be a new legal standard we are setting- for a murderer to review the school records and Facebook page of his teenage victim to determine whether or not he should have killed him?"

And O'Mara addressed allegations of being distasteful and going after details of Martin's past.

"Don't forget the state got my client's high school records before I even looked for Trayvon Martin's high school records, so I think the bar has been set," said O'Mara.

Martin's family said after his death there was a small group of hateful and racist people who attempted to destroy Martin's legacy. On the advice of counsel and with the intent to preserve Martin's public reputation, his parents deactivated all of his electronic accounts.

The defense also filed a motion to request review of certain discovery because it said some evidence was left out when it was initially handed over to them.

Zimmerman’s mother spoke out on CNN for the first time Monday night about the night that her son shot and killed Martin.

“I felt that the world had turned upside down.  To me it was like a nightmare.  I just couldn't believe what had happened,” she said.

Zimmerman is accused of shooting and killing the unarmed teenager in Sanford this past February. He claims he shot the 17-year-old in self-defense.

A hearing is scheduled next week where a judge will decide if he'll release that information.  The hearing will be at 1:30 p.m. on Oct. 19.
