Florida investigators may release a videotape of a jailhouse meeting between the grandmother of missing toddler Caylee Marie Anthony and her daughter.

Orange County, Fla., detectives are considering making public a video of the visit between Cindy Anthony and her incarcerated daughter, Casey, taken on Friday, MyFOXOrlando.com reports. A prayer vigil was held for the child Sunday night.

"We expect that the information might be available but it’s still under discussion," Capt. Angelo Nieves of the Orange County sheriff's office told FOX News, noting that the video is public record.

Nieves said the police are looking over the tapes to see whether they hold any clues to where the missing toddler may be.

"We have a family that is extremely distraught here, and parents and a brother that are also trying to get to the bottom of the missing child," Nieves told FOX News. "Where is Caylee Anthony? That’s what they’re trying to discover as well as us."

Cindy Anthony and her son, Lee, visited Casey on Monday after saying over the weekend that their loved one is innocent.

"My daughter, her No. 1 priority has always been Caylee’s safety and that’s why I know when … Casey states that someone has taken Caylee that that is the truth," Cindy Anthony told FOX News on Monday. "Casey would do anything to protect her child."

Cindy Anthony, who plans to see her daughter in jail again on Tuesday, said Casey would be willing to talk to the FBI, since she doesn't trust local authorities.

"We are prepared to provide, at their request, any assistance with any investigative leads in other jurisdictions, any forensic assistance and any other requests that would be instrumental in Caylee's recovery," FBI spokesman Dave Couvertier told MyFOXOrlando.com.

Cindy Anthony said her daughter would be willing to work with authorities in drawing a composite sketch of a babysitter who Casey Anthony claims she'd left the child with when she disappeared. Caylee was not reported missing for more than a month.

Lee Anthony mentioned two other people who supposedly know the babysitter, Zenaida Fernandez Gonzalez, but he acknowledged that he had never met Gonzalez, MyFOXOrlando.com reported.

"I'm going to speak for myself first ... if I can do that. The reason why I never met this babysitter before is because I don't live at this residence. Whenever I come over, typically Caylee is here with mother or sister or that," Lee Anthony said.

Investigators told FOX News on Monday that they'd been in contact with several Zenaida Gonzalezes, but none were the babysitter.

"Zenaida Gonzalez is quite a common name," Dep. Carlos Padilla told FOX News on Monday, adding, "We’ve spoken to a Zenaida Gonzalez; we haven’t been able to speak with the Zenaida Gonzalez."

Cindy Anthony told FOX News on Monday "we’re frantically looking for this person."

Cindy Anthony says her daughter is afraid something may happen to Caylee and other members of the family.

Cindy also lambasted the media in what she said was inaccurate coverage.

"News media reaches out to people who know nothing. Why does the media want to harass innocent people?" she asked.

Cindy also expressed her displeasure with investigators on the case.

"Every time they call, they ask to speak to my husband or Casey's brother. They're treating me like a child. I'm not a child," Cindy Anthony said.

Casey Anthony is charged with child neglect, making false official statements and obstructing a criminal investigation. She's being held on $500,000 bond and has been named a person of interest in what Florida prosecutors say is beginning to look like a homicide investigation.
