I smell a cover-up!! I always had a feeling the parents knew more than they let on. 

ORANGE COUNTY, FL– The FBI is investigating an email, obtained only by Eyewitness News, and legal experts say what’s in it could land Cindy Anthony in a jail cell for obstructing justice.

If the FBI finds the email is legit, it could prove Cindy was deliberately hiding evidence from detectives and, while Eyewitness News investigates the possible cover-up, the state wants the Anthony family to shut up.

When Eyewitness News obtained an email from Larry Garrison (read the email), it was handed over to the FBI because of the explosive evidence inside. The email says Cindy gave investigators the wrong hairbrush when they asked for Caylee’s brush in late July to compare DNA from her hair to the hair they found in Casey’s trunk, where it smelled of death.

Eyewitness News told the FBI about it and now they’re investigating whether Cindy has tried to sabotage the investigation.

Cindy Anthony tries to give the appearance that she’s cooperating with investigators, but Eyewitness News has learned she and her husband George have been stalling for weeks to answer their follow-up questions in the investigation.

Then Tuesday, a controversial email surfaced. It appears that the Anthonys’ former spokesman, Larry Garrison, says he confronted Cindy by email about why she gave Casey’s hairbrush, instead of Caylee’s hairbrush, to investigators who wanted a DNA sample.

Garrison said Cindy’s emailed response was: “I never lied. I just never went to my bathroom to get the hairbrush that I used only for Caylee.”

Eyewitness News passed the email along to FBI Special Agent Nick Savage, who told Eyewitness News Tuesday: “The appropriate weight will be given to this like all other information received. Law enforcement will address this matter as it relates to the investigation.”

Eyewitness News legal analyst Bill Scheaffer told Eyewitness News the obstruction of justice statute could apply.

“If she knowingly gave the investigators the wrong hairbrush, then I think there’s enough elasticity in this statute that one could bring a charge of obstructing justice,” Schaeffer said.

It is unlikely the Anthonys would be charged since they lost their granddaughter, but the issues could affect their credibility if they try to defend Casey in court.

So is this “obstructing justice?” Eyewitness News looked up the legal definition: “An attempt to interfere with the administration of the courts, the judicial system or law enforcement officers, including threatening witnesses, improper conversations with jurors, hiding evidence, or interfering with an arrest. Such activity is a crime.”
