This one Casey Anthony trial update will catch you up on two days of testimony — well, two half-days really — Saturday morning and Monday morning. On Saturday (day 16), the jury heard from an entomologist (insect scientist) who testified that 1) insects found in the trunk of Casey’s car were the kind of insects typically associated with decomposing bodies (e.g. “coffin flies”), and 2) insects found around Caylee’s remains indicated that the remains had been in the location for a period of several months. Two crime-scene investigators further described both the layout of the scene where Caylee’s body was found and specific items of evidence recovered there. Also on Saturday, a graphics expert who constructed a 3-D map of the scene where the body was found explained how the map was made. Monday (day 17) was an “all-FBI” day. An FBI hair expert testified that hair found in Casey’s trunk matched hair found both in Caylee’s hairbrush (although that’s not proof positive of identity) and in Caylee’s skull (remains) and that hair in the trunk and skull showed signs of progressive decomposition. The prosecution wanted to show a sequential presentation of digital photos to the jury to illustrate this witness’ testimony, but the judge disallowed that because the defense hadn’t had a prior opportunity to review the presentation and submit it to counter-expert analysis. Instead, the jury was shown limited photographic evidence to illustrate differentiating characteristics of a hair from a dead body. A second FBI agent testified about the duct tape found on the skull. She explained that she found no fingerprints on the tape but that she did find the outline of a heart on it, which she analogized to the outline that often remains on living skin after someone removes an adhesive bandage (e.g. “Band-Aid”) from it (and which, by the way, I think is more likely to have been placed there by a woman, e.g. Casey, than by a man, e.g. Casey’s father George). At that point, the prosecutor’s next witness wasn’t yet available to testify — apparently because he (the prosecutor) had expected the excluded picture presentation to take up significant time — so the judge recessed court for the day, half a day early. According to the judge, the prosecution is expected to finish its initial presentation (“case in chief”) late Tuesday or Wednesday, followed by 8-10 court days of testimony from witnesses called by the defense (whom the prosecution will still have the opportunity to cross-examine of course), followed by closing arguments from each side, which means that the jury could start deliberations toward the end of next week or the beginning of the following week. Stay tuned, especially to the Joy Behar show Monday night on HLN (10 p.m. Eastern, 9 p.m. Central), where I’ll again be discussing developments in the Anthony case with Joy!
