A Florida grand jury Tuesday returned a sealed indictment in the case of missing toddler Caylee Anthony after the child's grandfather testified.

Caylee has been missing since June but her absence wasn't reported for weeks.

CNN and the Orlando (Fla.) Sentinel report the name of the defendant won't be released until an arrest is made. Caylee's mother, Casey Anthony, 22, has been under suspicion and her lawyer told CNN she would surrender if she is named in the indictment.

"She's not running from this," attorney Jose Baez said. "She's doing her best to stand strong, to stand up to the powers that are working against her. And they threw the kitchen sink at her a long time ago."

George Anthony, Caylee's grandfather, Tuesday arrived at the Orlando courthouse to face a grand jury convened to determine if probable cause exists to indict Casey Anthony, CNN reported.

"This is going to be very hard for me to do," George Anthony told reporters gathered outside the courthouse. "The focus has always been on my granddaughter and always will be. I love my daughter, I love my wife, I love my son."

Caylee, 3, has been missing since mid-June, but Casey Anthony didn't call police to report the girl had disappeared despite being urged to do so by family members. It was Caylee's grandmother, Cindy Anthony, who eventually reported the girl's disappearance.

Meanwhile, reports surfaced Monday that volunteers searching for the missing girl had found a dress similar to one known to have been worn by Caylee. A volunteer leader told WKMG-TV, Orlando, the dress was discovered in a wooded area near Orlando Regional Airport.
