Expert: Peterson researched extensively before San Francisco Bay trip
~ Prosecutors work to show premeditation ~

August 4, 2004 - Story in part by Harriet Ryan

Scott Peterson looked for used boats on the Internet a day after a friend of his mistress confronted
him about being married.  Prosecutors put a computer expert on the witness stand to help prove
their theory that Scott  used the Internet while plotting the murder of his pregnant wife, Laci.


Five computer hard drives seized from Peterson's home and office showed he checked several Web
sites using terms such as "pacific, boat ramp" and other seemingly innocuous words for information
on fishing,
currents in San Francisco Bay and area boat ramps, and to purchase a gift for his mistress,
Lydell Wall of the Stanislaus County Sheriff's Department High Tech Crimes Task Force testified.


The expert walked jurors through a minute-by-minute account of Peterson's Internet
usage on one particular weekend about two weeks before his wife, Laci, disappeared.


He said sales ads for used boats had been searched on the Modesto Bee & Fresno Bee Web sites on
Dec. 7& 8, 2002.  Scott used one of four laptops he owned to search ads on Saturday December 7, 2002.


The following day, he visited a plethora of Web sites about the San Francisco Bay and
looked at maps, fishing reports and a U.S. Geological Survey chart of water currents.
The chart was "clickable," allowing users to enlarge specific areas, Wall said, and
Peterson zoomed in on an area of the bay that included Brooks Island.  He later told
police he was fishing off Brooks Island December 24 when his wife went missing.


A hydrologist from the USGS is expected to testify that the location of Laci Peterson's remains
and those of the child she was carrying indicate they floated ashore from a position near the island.


The day after he researched the currents, Peterson bought a 14-foot fishing boat and told  Amber Frey, that
he had once been married but had "lost" his wife and would be spending his first Christmas season alone.


Prosecutors have hinted that Peterson hatched the murder plan that
weekend after learning his mistress was about to find out he was married.


Prosecutors allege Peterson murdered his wife, Laci, in their Modesto home around Dec. 24, 2002, then
drove to the bay and dumped her weighted body from a
small boat he had purchased just weeks earlier.
The badly decomposed remains of Laci Peterson and the couple's fetus
washed ashore in April 2003,
not far from where Scott Peterson said he launched a solo fishing trip the day she vanished.


The Dec. 7 date is important because Shawn Sibley, the woman who set Peterson up with Amber Frey,
his mistress, testified earlier in the trial that she confronted him on Dec. 6 after learning he
was married.

Wall also said Peterson received e-mails from Sibley a month
before his wife went missing but did not discuss the contents.


Wall also analyzed e-mail and said one December 23 message concerned a gift Peterson had shipped
to Frey. The e-mail receipt identifies the item as a "Star Theater 2." According to its manufacturer, the
Star Theater 2 is a home planetarium that projects light in the shape of stars and planets on ceilings.


Peterson's second date with Frey included star-gazing, according
to a police report obtained by Court TV's Catherine Crier.


Wall also showed jurors files from eBay that indicated Peterson was selling a diamond watch
inherited by his wife. Her sister, Amy Rocha, testified that Laci Peterson found the watch too
gaudy to wear. Prosecutor Dave Harris noted the online ad listed Scott Peterson as the seller.


Wall said Peterson thoroughly researched how to fish for sturgeon and striped bass on
San Francisco Bay. Peterson told police that's what he
was fishing for the day his
wife disappeared, but prosecutors say his gear was
not suited for catching such fish.

Wall later testified that Peterson searched Web sites from the computer in the
warehouse where he stored the boat prosecutors allege he used
to dump Laci's body.

He said Peterson spent about 26 minutes on the computer on the morning
of Dec. 24, 2002 — the same day prosecutors claim he disposed of the body.


The 31-year-old defendant always appears engaged in court proceedings, but as Wall described his Internet
habits, Peterson seemed to pay especially close attention. He whispered to his lawyers while flipping through evidence binders and occasionally pointing at the large projection screen displaying images of the sites.
