"Sex is good with us, really good. And I know it's not the only reason you want to see me," Casey told him (read full conversation - explicit).

"Good, I hope so, but Jesus three week droughts blow," Rusciano replied. "So again, bring your little fine ass over here."

Rusciano was a sheriff's deputy later fired for lying about the affair. It seems like Casey's daughter Caylee was the problem in the relationship.

"Ha, want me to bring the little snot head?" Casey asked. "Didn't think so."

Later, in a police interview, Rusciano was asked about that comment.

"You believe that when she, when she's referring to the "little snot head" here, the child, she's talking about her daughter?" an investigator asked Rusciano on August 18.

"Yes," he replied.

Casey blamed her mother, Cindy, for not being around to take Caylee.

"Not your mom's fault, call that other bitch," Rusciano told her.

He's referring to Zenaida Gonzalez, the nanny Casey always talked about, but deputies never found.

During the Instant Message conversation release Friday, Casey often refereed to Caylee as passed out. But what does passed out really mean? Eyewitness News has reported that chloroform was found in the trunk of Casey's car. Casey makes it clear her own daughter tires her out.

"Seriously, spending the day with Caylee is 10 times more exhausting than working a 12-hour event," she said.
