    30 or more cases in Florida. He is also a farmer, formerly a rancher.

    JA submits Dr. H as an expert.
    JP accepts him as expert witness

    Dr. Haskell's degrees, all four of them, are from Purdue University in Indiana.

    Doesn't bother me, but I'm sure the poor court reporter has an opinion

    Showing GA...looks composed but serious. Maybe his daughter could take lessons.

    Ugh...maggots and flies. Coffin flies.

    Problem is that it's very difficult to identify unless we have an adult of the species.

    Got adults from the sealed evidence from the trash bags and paper towels.

    Found 15-20 adults to positively identify the species.

    Entomology is the study of insects.

    Contacted in Sept. 2008 by Michael Vincent of OCSO. They discussed vehicle (Casey's(.
    Vincent said there were bugs in the car and sent Dr. Haskell samples of maggots and larvae. He received the samples in Sept. 2008.

    The problem with the group was it was 4 different types of flies and they're difficult to identify the species if MV had any material containing adult flies. And MV said there was such in the garbage bag in a the car. NH received the bag and examined it and vound adult flies and he had the means to do a causative identification.

    JA: describe the process of your exam as you opened the bag
    Dr. H: a number of paper towels, as he opened the paper towel there was an abundance of larvae & puperium. Shook them out into a pan. Very small flies.

    paper towels had cocoon stage and larve and a few adults--all dead. describes larve as being less than 1/16th of an inch.

    Associated the presense of the flies to the substance on the paper towels.

    substance was requested to be analyzed. Evaluation showed that the material adiopocere (fluids from decomposing materials)

    Dr. H had the towels analyzed. He says it was found to be adopocere.
    JB: objection
    JP: objection over ruled

    NH found 100s of tiny forest flies and once he contacted an expert in these flies, he sent adult flies to them for positive identification. The species of forest flies would be found regularly in decomposition--very, very common.

    Specimens int he white plastic bag and the bag contained paper towels. And I tried to pull them apart and there was an abundance of larvae and pupalea (sp?). He noticed adult flies as well in the paper towels. Very small larvae.

    When he opened the town, there was a substance the flies were attracted to. And he surmised it was decomp that drew the flies. He then requested the material be analyze the material. The material was went to Dr. Vass at Body Farm. The material was adipose material--decomp.

    (excuse my spelling in my posts please)

    Any other bug evidence? Yes of a leg of a fly---blowfly. Southern species of blowfly present at that time of year.

    The blowfly likes to feed on about anything. Doesn't have to be human decomp or animal decomp.

    did you find other entomol. evidence

    there was a leg of a fly, one of the species in a group of flies

    blow fly leg, 90 different kinds in N. america
    one of 7 present at that time of year

    are any of the flies specific for human decomp?
    No
    Are they common in human decomp?
    yes

    (fly name I didn't catch) is common in any decomp., likes to feed on anything

    suppose a child's body is in a car and then moved , does it fit the evidence?

    yes

    JA asks if these flies are exclusively found in human decomp
    Dr. H says no

    After NH received Dr. Vass' report, he determined the impact of decomp and presence of these insects, and developed an entomological timeline. A blowfly leg was in the towels.

    The flies are not specific to human decomposition.

    JA: The body of a young child was stored in that car for a period of time and does that fit with your conclusions?

    Absolutely. Decomp passes through many stages and as tissues goe from one biochemical and change to another and another throughout decomp, they have different insect groups coming in and feeding a that particular time. Blowflies usually are the first ones in and they are there almost immediately, esp. in Fla. As decomp progresses, the biochemistry changes and the blowflies are no longer interested. They drop out and other groups kick in. The forest fly comes early after the blowflies.

    Dr. H now explaining how the presence of these flies fits with the decompositional event in the trunk . Says blow fly are first ones in, within seconds or minutes if temp is high.
    As decomp progresses, the biochemistry changes and the blow fly is no longer interested.
    The next fly comes in when decomp is set in, a few days, or weeks, they are very tiny.
    They can get in through cracks, very small openings.

    Baez objecting. Says JA is leading. Overruled.

    The body was deposited very early into the trunk. As decomp progressed these small flies got into trunk (found a way in) and colonized.

    Have you see this fly in trunks in other cases? Yes.

    Dr. H says the body would have been deposited into trunk very early.
    JA: would wrapping the body in plastic bags delay flies getting to it
    Dr. H: yes, it would delay for days to the point blow flies may not be interested at all

    Dr. H: body could not have been in trunk very long because of heat in florida - made estimate that 3-5 days with the heat would have produced enough fluids to attract the minute flies that appeared on paper towels.

    Forest flies may come up to several months after decomp starts. Gnat-size flies--very tiny.

    You found an absence of the first decomp flies and a great # of the slightly later type of flies (forest flies)?

    This tells me the body had to be depostited very quickly into the trunk, the blow flies came, and the forest flies came later.

    What would be the effect of wrapping a body in a plastic bag? It delays decomp, and in some experiments, blowflies are no longer interested in the decomp.

    How much time would the decomposing material was in the car? Did you come to that conclusion.

    The body could not have been in the trunk for long. NH says the body was in the back of the car for 3, 4, 5 days and hence attracted the forest flies.

    When Nov./Dec of 2008, did you come inspect the vehicle yourself? Did you receive surprising news about the case?

    The remains of a little girl had been found.

    He inspected the area, as well as where the car was impounded. He went to the ME's office and examined evidence. He took entomological evidence from those places and examined those items.

    Dr. H: basically saying that the body was there many months, June or early July.
