Editing Scott Peterson (section)

===Evidence===
The only piece of forensic evidence identified was a single hair, thought to have been Laci's, found in a pair of pliers from Peterson's boat.<sup class="reference" id="cite_ref-26">[http://en.wikipedia.org/wiki/Scott_Peterson#cite_note-26 [26]]</sup>

Peterson changed his appearance and purchased a vehicle using his mother's name in order to avoid recognition by the press. He added two [http://en.wikipedia.org/wiki/Pornographic pornographic] television channels to his cable service only days after his wife's disappearance;<sup class="reference" id="cite_ref-27">[http://en.wikipedia.org/wiki/Scott_Peterson#cite_note-27 [27]]</sup> the prosecution suggested that this meant Peterson knew his wife would not be returning home. He expressed interest in selling the house he had shared with his wife,<sup class="reference" id="cite_ref-28">[http://en.wikipedia.org/wiki/Scott_Peterson#cite_note-28 [28]]</sup> and he sold Laci's [http://en.wikipedia.org/wiki/Land_Rover Land Rover].<sup class="reference" id="cite_ref-29">[http://en.wikipedia.org/wiki/Scott_Peterson#cite_note-29 [29]]</sup>

Testimony for the prosecution included Rick Cheng, a [http://en.wikipedia.org/wiki/Hydrology hydrologist] with the [http://en.wikipedia.org/wiki/United_States_Geological_Survey United States Geological Survey], and an [http://en.wikipedia.org/wiki/Expert_witness expert witness] on tides, particularly of the [http://en.wikipedia.org/wiki/San_Francisco_Bay San Francisco Bay]. Cheng admitted during his cross-examination that his findings were "probable, not precise"; tidal systems are sufficiently chaotic, and he was unable to develop an exact [http://en.wikipedia.org/wiki/Scientific_modelling model] of the bodies' disposal and travel. The prosecution explored an affair by the defendant with Amber Frey, and the contents of their taped telephone calls.

The defense suggested a prostitute accused of stealing checks from Peterson's mailbox may have murdered Laci, but Modesto police Detective Mike Hermosa did not indicate that the prostitute was ever a suspect in Laci Peterson's disappearance. Prosecutor Dave Harris noted that the checks were stolen after Laci vanished, meaning the woman was not involved in her disappearance.

Geragos seemed quite confident that Dr. Charles March could single-handedly [http://en.wikipedia.org/wiki/Exoneration exonerate] Peterson by showing that the fetus Laci carried died a week after prosecutors claimed. Under cross-examination, March admitted basing his findings on an anecdote from one of Laci's friends that she had taken a home pregnancy test on June 9, 2002. "Prosecutors pointed out that no medical records relied on the June 9 date and March became flustered and confused on the stand – and even asked a prosecutor to cut him 'some slack' – undermining his credibility."Summing up this key defense witness, Stan Goldman, a criminal law professor at [http://en.wikipedia.org/wiki/Loyola_Law_School Loyola Law School] in [http://en.wikipedia.org/wiki/Los_Angeles Los Angeles] said, "There were moments today that reminded me of [http://en.wikipedia.org/wiki/Chernobyl_disaster Chernobyl]." According to one newspaper account about Dr. March's testimony, "But by the end of his testimony Thursday, legal analysts and jurors closed their notebooks, rolled their eyes, and snickered when they thought no one was looking."
