A search warrant uncovers new details in the Caylee Anthony case, including what investigators were looking for.

The warrant also shows just how much mother Casey Anthony's been lying to investigators.

Casey Anthony told the cops she last heard from her daughter at noon on July 15th, in a call from the babysitter.

"I actually received a phone call today now from a number that is no longer in service," Casey said on that day, in a recorded phone call. "I did get to speak to my daughter for... about a minute."

Cell phone records show that Casey only got calls from her boyfriend at midnight, and a man named Kyle at 3:30 in the afternoon. Investigators have also cleared the Zenaida Gonzalez they've talked to, but there are over 400 women with that name in Florida.

Detectives were back at the home Thursday, and lots of Casey's clothing has been seized, including a gray pair of slacks that Cindy Anthony found in the abandoned family car when they got it back. Cindy washed those slacks because, she says, they had that same stinky smell that was in the car.

Divers will be out at lakes near the home this weekend, but Carlos Padilla says it's not related to Caylee.

"Keep in mind that this is something that was scheduled a while back, before this case even came to light," Padilla says. "Nothing is leading to her being in a waterway... It's just a training exercise."

Saturday is Caylee Anthony's 3rd birthday.
