M. Lee Goff, an entomologist and chairman of the Forensic Sciences Department of Chaminade University in Honolulu, said his review of the crime scene photos, morgue photos, weather reports and other evidence suggest that Danielle's body was exposed to insects as early as Feb. 1 and no later than Feb. 14.
"We're working on an estimate. We're not running a stopwatch here," Goff said. The defense has contended that there was no way Westerfield could have placed the victim's body where it was found in the East County community of Dehesa, because he was under close surveillance by police beginning Feb. 5. Goff was called to the stand to rebut testimony from two forensic entomologists called by the defense who testified that Danielle's body could not have been exposed to insects any earlier than mid-February, nearly two weeks after Westerfield came under police surveillance. Westerfield could face the death penalty if convicted of the kidnap and murder of Danielle. He also has been charged with possession of child pornography. Danielle was reported missing from her family's Sabre Springs home on Feb. 2. Her body was found in a wooded area near El Cajon on Feb. 27 after a massive search drew national attention. Westerfield, who lived two doors down from the van Dams, became an early suspect in her disappearance.
Insect evidenceWhen Danielle's naked body was found, investigators took extensive photos of it and its surroundings, then put bags over her head, feet and hands and wrapped the body in a sheet to preserve any evidence.Law enforcement officials called in forensic entomologist David Faulker to study the signs of insect infestation on the body to try to gauge when Danielle had died. But lead defense attorney Steven Feldman argued in his opening statement that scientific evidence would prove his client could not have killed Danielle. As it turned out, the prosecution never called Faulker to the stand and he was called by Feldman as a defense witness. Early in the trial, San Diego County Medical Examiner Brian Blackbourne testified that the girl could have been dead from 10 days to six weeks when her body was found. Faulkner testified July 10 that his analysis of the life cycles of the insects found on Danielle's body showed it wasn't available to insects until sometime between Feb. 16 and 18. On July 22, a second defense expert, Dr. Neal Haskell, testified that Danielle's body couldn't have been exposed to flies any earlier than Feb. 12.
Insect rebuttalProsecutors began rebutting the defense insect evidence on Thursday by calling Dr. William C. Rodriguez III, a forensic anthropologist for the Department of Defense, who testified that Danielle's body was in "an advanced state of mummification" that would have delayed insect infestation.On Tuesday, Goff reiterated testimony about insect lifecycles presented by the previous experts: You can calculate how long a body has been exposed to the elements by gauging the age of the maggots – fly larvae – growing on the body. Flies are quickly drawn to dead bodies and will lay batches of eggs on them. The development of the eggs into different stages of larvae and adult flies is then affected by temperature, humidity and other environmental factors. Using charts of known development rates, a forensic entomologist can look at the age of maggots found on a body and, factoring in the weather, can calculate when the eggs they hatched from had been laid. Generally, the warmer the weather, the faster the insects develop. Goff, author of "A Fly for the Prosecution: How Insects Help Solve Crimes," said he calculated the "post-mortem interval" date from the maggots on Danielle's body using temperature records and charts from a 2000 fly study. He said Faulkner appeared to have made his calculations using a chart of insect development from a study that used 80-degree temperatures, far higher than the rates in the San Diego mountains in February. Haskell appeared to have calculated his dates assuming that the activity of the "maggot mass" on the body would have raised the temperature of the mass, speeding up their development. In both cases, Goff said, the other entomologists estimated that the maggots would have developed much faster than he did, giving a much later date for the exposure of Danielle's body to the elements. Goff was scheduled to resume testifying – and to face cross-examination by the defense – after a lunch break.
Fiber evidence
A series of shirts and other orange-colored items brought to the San Diego Police Department crime lab were made from either nylon, cotton or a polyester-cotton blend, criminalist Tanya DuLaney testified. "Did the fabric of any of these items consist of acrylic in any manner?" assistant prosecutor Woody Clarke asked. "No," DuLaney replied. Prosecutors called DuLaney back to the stand in response to defense suggestions that investigators could have inadvertently cross-contaminated the two crime scenes with the orange acrylic fibers, which became a key piece of prosecutor evidence linking Westerfield with Danielle's body. On June 25, police criminalist Jennifer Shen testified that an orange acrylic fiber tangled in Danielle's plastic necklace at the time her body was found was similar to orange acrylic fibers found in laundry inside Westerfield's home and on bedding in his bedroom. On July 24, lead defense attorney Steven Feldman introduced into evidence several still images from television that showed police investigators wearing orange or orangish shirts as they entered and left Westerfield's house on Feb. 4 or 5. In response, the district attorney's office identified all of the police and search-and-rescue personnel shown in the photos, collected anything orange-colored they were wearing at the time and gave the clothing to the crime lab. That evidence consister of two orange long-sleeved shirts, an orange short-sleeved shirt, four reddish polo shirts, an orange rope, an orange strap, a black-and-red backpack, an orange hat and an orange dog vest, DuLaney said. Under microscopic and infrared examination, none of the fibers taken from those items contained any acrylic material, DuLaney said.
Trial's end in sightAt the start of today's session, Superior Court Judge William Mudd told jurors that there will be no testimony on Wednesday, but that testimony will resume Thursday and could conclude on Monday."It appears to me that next week you'll hear closing arguments and be in deliberations," Mudd said. The judge said that he had not yet decided whether to sequester the jurors during deliberations. Mudd also warned jurors not to read or view any material about the Westerfield case or the Orange County kidnap-murder of Samantha Runnion, in which the girl's mother blamed a previous jury for failing to convict her daughter's accused murdered in a previous sexual abuse case. "The fact is the case is not similar in any way, shape or form," Mudd said. |
Entomologist hired by prosecuter, yet called by defense.
Lack of testimony of Barb Easton for the prosecution(who was at the home that night...they called the rest of the pizza people).
Lack of DW's dna, hair, prints, etc. in the VD home (while there are unidentified prints in the home).
Lack of evidence of Danielle in DW's SUV.
Character witnesses for DW, as opposed to the lying pizza group.
Porn being surfed while DW is being questioned.
Shell casing
Viagra Pill
BVD's nervousness with Barb around Danielle...BVD was not nervous about Danielle being around DW at the cookie sale.
Dope smoking having to be dragged out of the VD's after 17+ hours of their daughter missing.
"Swapping" having to be dragged out of the VD's after 17+ hours of their daughter missing.
Dumping of body at Dehasa road vs. the desert.
People coming over to house at 2:00am to "eat pizza"...c'mon go ahead and say it...nightcap, a drink, c'mon, no one had any liquor after being out drinking all night. More likely, coke, and that's why they won't admit "anything". I'll bet coke after a viagra will have you ready to "hook up" with anything, even layla.
Inviting strangers back to your house to "party".
Having lock reversed on the garage door, so people would not smoke inside, yet DVD thinks the slider is left open because people were smoking in the kitchen.
Bill Libby trip "story"...why doesn't dusek have him verify DVD's "story. Afraid of FELDMANIZATION?
Anyway, putting a man to death is pretty final. Unless the jury is made up of fools, which it may well be, I see "reasonable doubt" ALL OVER THIS CASE.
Dusek should have considered the lesser charge, IMO.
Think you want to let her know?
No. I haven't figured that out yet. Next time my grandson comes to visit I will have him show me how.
He changed more than his tune. He changed how you figure math too.
Tehehehehehehehehehehehehehehe!
