I'm like the last person on earth to read up on the latest tabloid story but discovery of a body caught my attention. I found this Wikipedia link useful for a quick summary... [link to en.wikipedia.org]

Caylee Marie Anthony
(born August 9, 2005), from Orlando, Florida, has been missing since June 2008 and has attracted national attention in the United States for the mysterious and dubious circumstances of her disappearance and possible death. Her mother, Casey Anthony (born 1986), was indicted on October 14, 2008, for first-degree murder of Caylee. Police found Casey Anthony's account of Caylee's disappearance suspicious after learning that Casey had not reported her daughter missing for over a month. The last time Casey Anthony claimed to have seen Caylee was on June 9, 2008, but the child's disappearance was not reported to police until July 15, 2008.

Disappearance
Caylee Anthony was first reported missing to authorities on July 15, 2008. Caylee's grandmother, Cindy Anthony, reportedly called 9-1-1 when her daughter Casey Anthony, the mother of Caylee, would not produce the grandchild. Cindy Anthony had not seen her granddaughter for weeks and became alarmed when she smelled the odor of a "dead body" in the trunk of Casey Anthony's car. (Cindy Anthony later revised her account, stating that the smell was from old pizza.)

Probable death
During the investigation, police discovered hair samples and a stain in the trunk of Casey Anthony's car. Though there were claims that the stain was from the victim's blood, at the time this fact had not been publicly confirmed. Instead, a lead investigator on the case said the hair was the major deciding factor leading authorities to believe that Caylee had indeed been in the trunk of Casey Anthony's car. Together with these findings, authorities "air tested" the area of the car trunk to determine if a decomposing body had been stored there. The results of the air test were sent to the University of Tennessee Anthropological Research Facility for forensic examination. These results confirmed that a body had been in the trunk.
