Day One: "DNA 101"

Oct. 29 (AP) — A hair found in a pair of pliers on the boat Scott Peterson took fishing the day his wife disappeared matched a genetic sample from Laci Peterson's mother, an FBI expert testified Wednesday, as prosecutors sought to have him tried in the murder of his wife and unborn son.

For much of the day inside a packed courtroom, FBI lab supervisor Constance Fisher testified about the disputed method of DNA analysis she specializes in that can show a genetic match between a mother and child.

She testified that a one-inch strand of hair found on pliers in the boat did not match Scott Peterson, but did match a swab of DNA taken from the mouth of his mother-in-law, Sharon Rocha.

Defense lawyer Mark Geragos is challenging the admissibility of the testimony, saying the analysis was the subject of a "raging debate" in the scientific community and suggesting that the hair sample may have been contaminated or tampered with by law enforcement.

The technique has not been widely accepted in courts, and it was only ruled admissible once in a California state court, in the case of an accused murderer in San Diego.

With the exception of a brief mention of Laci Peterson's family at the start of the hearing, the 27-year-old substitute teacher's name was never uttered again during the daylong hearing in Stanislaus County Superior Court.

The hearing is expected to last into next week, after which Stanislaus County Superior Court Judge Al Girolami will decide if Peterson is tried on two counts of murder that could lead to the death penalty. ..........

Peterson evidence set to be revealed
The public will hear at least some at the preliminary hearing.

MODESTO -- The public's first real look at evidence against double-murder suspect Scott Peterson is expected Wednesday, when prosecutors begin laying out a legal case that has been under wraps for 10 months. "Everything will be a revelation to us," said Ruth Jones, a criminal law professor at McGeorge School of Law in Sacramento and a former prosecutor. "This case is unique in that sense."

Peterson's preliminary hearing, which likely will last five days, could demonstrate the strength of the prosecution's case and outline the possible trial. The hearing that begins Wednesday is to determine whether there is enough evidence to try Peterson in the deaths of his 27-year-old wife, Laci, and their unborn son, Conner. Prosecutors are seeking the death penalty.

It's unclear how much evidence the prosecution will unveil at the hearing, because it's relatively easy to have a defendant held for trial. For that reason, the defense rarely calls witnesses, protecting them from cross-examination.

But this case is different, legal observers said, pointing to widespread public scrutiny that has influenced legal tactics and might affect the trial.

"There are two battles going on here," said San Francisco Deputy District Attorney James Hammer. "The legal battle and the PR battle."

In the legal battle, attorneys are poised to spar over an array of evidence the defense wants kept out of court, including information from wiretaps, electronic tracking devices, DNA testing and scent-tracking dogs.

The judge also is to hear a defense argument that a potentially key piece of evidence -- a single hair found attached to a pair of needle-nose pliers in Peterson's boat -- likely was "altered" while in police possession.

The hair could be a critical piece of physical evidence linking Laci Peterson to the boat her husband said he took fishing on Christmas Eve, the day she was reported missing.

The defense's challenge of the evidence signals a wider tactic of trying to show that investigators acted improperly, echoing the O.J. Simpson murder trial, legal observers said. A jury acquitted the former football star in 1995 of killing his ex-wife and her friend.

"It's a very important strategy," said Professor George Bisharat, a criminal procedure specialist at Hastings College of the Law in San Francisco. "You really saw the potential impact in the sense that there was law enforcement wrongdoing in the O.J. Simpson case."

Like the Simpson case, the disappearance of Laci Peterson, a pretty substitute teacher with deep dimples and a captivating smile, has become staple fare for cable television, supermarket tabloids and newspapers on both coasts.

For months, hundreds of volunteers and law enforcement personnel scoured fields, reservoirs and waterways from the Sierra foothills to San Francisco Bay for Laci Peterson.

In April, passers-by discovered Laci Peterson's decomposed body and that of her son about a mile apart along the eastern shore of the bay, several miles from where Peterson said he had gone fishing.

My folks take Halloween very seriously. Every year, in early October, they set out to convert their nice Walnut Hills home into a bastion of evil by adorning every room with dark lights, nightmarish knick-knacks, voodoo accessories and whatever it takes to make the devil feel at home. They bring the ghouls out of the basement and turn the lawn into a graveyard.

All of this culminates in a big bash that occurs on a Saturday night around Halloween. My sister won't come, though, because several members of her church "wouldn't agree with it." Really, she's just scared, but won't admit it. I'm willing to bet that it's not a matter of this particular demonization, I mean denomination not agreeing with these aspects of the holiday in question, but really they're just scared.

After centuries gone by, the devil still gets a bad shake. We may have come a long way from burning at the stake those under suspicion of his influence, but still when a puzzling situation arises where we have no logical conclusion, we must have the devil at hand to blame.

Take the Laci Peterson case, for instance. The preliminary hearing to determine if Scott Peterson will stand trial for the murder of his wife just started. Scott Peterson has been held without bail since authorities arrested him at the Mexican border with his hair bleached and $10,000 in cash.

The defense is trying to prevent prosecutors from being able to present certain evidence to the court, such as DNA analysis of hair clippings from Peterson's wife found on pliers in his boat and information gathered from wiretaps and global positioning systems. The defense has implied that the "real killers" are worshippers of the dark lord.

That's right, Peterson died at the hands of a satanic cult, according to this theory.

Clearly there must be real compelling evidence to support this claim. The defense is unable to indicate that there are bad people at large other than Peterson himself, but merely a "satanic cult." California murders often seem due to circumstances resulting from a "satanic cult."

The Son of Sam is an instance of incriminating the devil. Lucifer was blamed for the psycho that randomly went out and killed people that summer of seventy something. David Berkowitz wasn't in league with the devil, as many have assumed, because of satanic associations made with the case, that he was possessed by some evil power. He didn't say "the devil made me do it," but he was forced to kill by his "father," who he ........

Scott Peterson, right, and defense attorney Mark Geragos listen as FBI DNA expert Constance Fisher testifies Wednesday before Judge Al Girolami. LAURIE McADAM/THE BEE

Wiretaps secretly recording Scott Peterson's telephone conversations while he was under police surveillance will not be used in his double-murder preliminary hearing, prosecutors said Wednesday.

Nor will they present evidence from GPS tracking devices placed on his vehicles to monitor his movements, Senior Deputy District Attorney Rick Distaso said moments after the long-awaited hearing got under way in Stanislaus County Superior Court.

The defense, however, still wants to raise the issue that the wiretaps were improperly conducted.

The bulk of Wednesday's proceedings was dedicated to an FBI expert's detailed testimony about mitochondrial DNA testing.

An afternoon of technical cross- examination by defense attorney Mark Geragos was aimed at showing the mitochondrial DNA testing process was unreliable and the results should not be admissable in court.

Geragos also contends that police mishandled a single strand of hair found attached to pliers in Peterson's boat.

Mitochondrial DNA tests showed that the hair did not come from Peterson but could have come from his wife, Laci, according to the prosecution.

Peterson told police he took the boat on a fishing trip to San Francisco Bay on Dec. 24, and his wife was missing when he returned to Modesto that evening. She was almost eight months pregnant at the time.

Her body and that of her son, Conner, were found in April along the bay's eastern shore, several miles from where Peterson said he went fishing. Police arrested Peterson on April 18 in the San Diego area, where his family lives.

Peterson, 31, is charged with murdering his wife and their unborn son, and prosecutors are seeking the death penalty.

Prosecutors are presenting some of their evidence during the preliminary hearing, slated to last five days, and Judge Al Girolami will decide whether there is enough evidence to hold Peterson for trial.

At the outset of the hearing, Geragos asked Girolami to order attorney Gloria Allred out of the courtroom. Allred represents Amber Frey, who was Peterson's girlfriend when Laci Peterson disappeared.

Frey, 28, of Fresno has cooperated with authorities since she contacted police on Dec. 30. She said she did not know that Peterson was married when they began their relationship.

You're right about the husbands not knowing what the wives are wearing. I could see a husband being asked what his wife was wearing that morning and being unable to remember.

But a husband who cared and knew he didn't have a clue, would have said so. He wouldn't have made up a description of clothing which might throw the whole search off. He'd just be honest and tell the searchers and police, I honestly don't know what she was wearing this morning. A concerned husband would then have tried to go through her clothes, perhaps with the help of a female relative or friend, to figure out what was missing.

Ya done real good, kid! We're going to send you to New Mexico! They're short a scientist out there from a few years back. We want someone totally fluent in the language! You're it!

Scott: "but last time I saw her she was upside down"

Wicked one--but I can't help it, that's hilarious!!

I'm convinced that Chris Prixley is a deliberate shill for Geragos.

That makes three of us. I said last night, I think Pixie is on Geragos' payroll. Really.

You don't think Dr. Lee is gonna interrupt his career of paid TV appearances just b/c someone has him tapped as their expert, do you? How would he keep making those big bucks?

I realize that these experts like Lee and Wecht, and Baden too, all went to school for a long time, and I realize that they know a LOT, but as for their TV appearances, it is very clear to me that they are there to simply sit and look pretty and say pretty much NOTHING meaningful.

>>It is hard to think that someone who has what she has in her home and family would want to run away with a wierdo and live like a bum.<<

She's a teenage girl. Teenage girls rebel in all kinds of illogical ways and she wouldn't be the first who wanted to get away from parental control even if she had to live like a bum. It's only after kids do that for a while that it tends to loose it's appeal.

She's a beautiful, smart girl, but I've thought there was something wrong with her ever since I learned the story of what really happened.

>>You're right about the husbands not knowing what the wives are wearing. <<

Well, yeah, I agree under normal situations that husbands don't pay a lot of attention to what their wives are wearing. BUT when a husband murders a wife and dumps her in the ocean, I bet he remembers exactly what she was wearing.

Snotty had to lie. How could he explain to Amy and Sharon that Laci was wearing the same clothes two days in a row??? They knew her better than that.

Very good thoughts. So we are anticipating that Amy will say, no, I never could find that outfit Laci was wearing on the 23rd, and I went through all of her clothes.

Next question: suppose Geragos asks her, okay, well did you find her black maternity pants and white, longsleeved maternity top? Were they in the house?

If Laci had more than one black pair of pants, and more than one white longsleeved maternity top, then the answer won't matter much. But suppose she only had one outfit like that, and suppose Scott was diabolical enough to have thought to get rid of it?

Yes, you can listen to John and Ken online. They are at www.kfi640.com from 3:00 - 7:00 p.m. PST. They probably will have a Peterson update segment at least twice if not more during their show. They go with whatever is most pressing, and lately that has been the fire coverage -- in fact, KFI had them on from 1pm til 7 on Monday through Wednesday.

I hope you enjoy them. They know all the goodies about this case like we do and make many similar comments.

I don't think I would remember what my husband had on most days. Maybe not even my kids! Even the ones I DRESS! Is that bad? Do I have Alzheimers? LOL. A hopeful LOL...
