ORLANDO, Fla. -- In an e-mail obtained by Local 6 News that was sent by Cindy Anthony three days ago, she wrote that her daughter, Casey Anthony, never harmed Caylee and that fact would be proven, presumably in court.

Casey Anthony, 22, remains jailed on first-degree murder charges in the death of her daughter, Caylee, whose remains were found last month in a wooded area near the Anthony family's Orange County home.

In the e-mail obtained by Local 6 News, Cindy Anthony wrote to Lois Peter, "As for my daughter, she never hurt Caylee and that will be proven. She loved her deeply."

In August, Peter's 12-year-old granddaughter hosted a candlelight vigil for Caylee in St. Cloud while Casey Anthony was home on bond. Casey Anthony sent the girl a bracelet, a letter and some e-mails, which prompted Peter to unsuccessfully seek a restraining order against Cindy Anthony, who continued to correspond with the girl after Casey Anthony returned to jail.

In recent days, Cindy Anthony and Peter have exchanged biting e-mails, with Cindy Anthony telling Peter that she would not be invited to Caylee's funeral.

Peter responded in an e-mail, saying, "I would not want my granddaughter around a person that condones her daughter killing her own child. At least I know where mine is."

That's when Cindy Anthony replied, "As for my daughter, she never hurt Caylee and that will be proven, she loved her deeply."

Cindy Anthony and her husband, George Anthony, have avoided the media since Caylee's remains were discovered, allowing their attorney to speak on their behalf.

The last time Cindy Anthony spoke publicly was on CNN's "Larry King Live," the day before Caylee's remains were found. She also defended her daughter during that interview.

"I can say with 100 percent of my being (that) Casey has nothing to do with Caylee's disappearance," Cindy Anthony said.

"How are you holding up?" Larry King asked.

"We take one day at a time. A lot of sleep lost, weight lost," Cindy Anthony said.
