The case of missing Caylee Anthony has captivated the nation. Here are the latest developments.

• Detectives visited the home of Caylee Anthony's grandparents today after being contacted by Cindy Anthony to discuss her granddaughter's disappearance. After authorities left, reporters bombarded Cindy's front door, but she had little to say. She admitted that she doesn't plan to see daughter Casey before Saturday, Caylee's third birthday.

• Yesterday, police also visited the Anthony residence and took away four to eight bags of evidence. That is at least the fifth time they have been to the home.

• Last night, Nancy Grace reported that Casey Anthony might have posed as the mystery babysitter, Zenaida Gonzalez, to look at a unit at Sawgrass Apartments. She may have signed the sitter's name during a visit to an apartment complex and written in a visit date within the time frame of the child's disappearance. She later took police to that apartment and told authorities that's where she'd left Caylee.

• The search warrant executed Thursday in the case revealed new information. Nancy Grace reported Thursday night that the private phone call that Casey supposedly received from Caylee never came in, according to phone records. Also, the warrant revealed that Cindy Anthony had found a pair of gray-and-white pinstriped pants in Casey's car that "smelled like a dead body" and unwittingly washed them. Those pants were the same ones Casey was wearing the last time Caylee was seen alive.

• Police diving crews plan to search one of the local lakes near the Anthony residence on Friday.
