LOUIS POST-DISPATCH MONDAY, FEBRUARY 21, 1994 ww www m'w REVIEWS Evidence Genetic Evidence A photograph of Exhibit part of the genetic test that was the linchpin of the prosecution's case against Stuart Heaton. A genetic expert says the exhibit may tend to exonerate Heaton. 'Burning Feet9 Company: Swirling, Abstract Artistry DANCE ri 1 01 11 1 1 Jk By James Wierzbicki Ol the Post-Dispatch Staff With her latest composition, "Bri-colage," choreographer Suzanne Grace has taken a bold step in the direction of large-scale, abstract modern dance. She has created lengthy works before, but they have been of the quasi-narrative sort, and typically their sections have been so different from one another that they came across more as separate pieces than as components of an extended whole.

Grace also has purely sculptural dances in her repertoire, but most of them are miniatures that explore the potential of a single gestural idea. "Bricolage," premiered by Grace's Burning Feet Dance Company at the Center of Contemporary Arts over the weekend, gives the audience neither plot nor program. It lasts almost 40 minutes and is set for eight dancers, none of whom takes on the guise of a specific character. Rhythmically vague, bell-like sounds dominate the accompanying electronic score by Rich O'Donnell. Grace's movement, too, stays free of rhythmic restriction, and it is as complex as it is consistent; it all seems to emanate from the simple skipping-thrusting pattern presented near the start and at the very end, but the variations quickly grow too intricate to follow, and after a while their cohe-siveness is not so much seen as Debate Set On Plan A chemist from Greenpeace and the head of the Missouri Department of Natural Resources will join others tonight in debating the merits of burning dioxin.

The discussion is scheduled for 7 p.m. at the Old Eureka Junior High School, 500 North Central Street in Eureka. The panel discussion is sponsored by the Dioxin Incineration Response Group, which opposes incinerating dioxin-contaminated soil at dence even though Allen maintained that it did. "The fact that Heaton has a 5.51 kb band that does not show up in the evidence could be used as exclusionary evidence," said Krane. In an earlier interview, before Krane's analysis was released, Allen had stressed that no bands in the test excluded Heaton.

"Remember, we didn't exonerate this guy," he said. Krane also pointed out that the evidence in Exhibits and contained bands from other, unidentified people. Normally, the evidence shows just four bands of DNA two from the victim and two from the suspect. But the samples from the Naab crime scene had additional bands. "In evidence lane we see not just four bands but as many as a dozen," said Krane.

"Then you have to start wondering where did those extra bands come from. Was it a gang rape? Could someone have bled on the evidence? Was there a technical error? Did she have sex with someone else before the murder?" At the time of her death, Naab was planning to marry her boyfriend and was three months pregnant. 'I don't want to say that Allen was wrong," said Krane. "But based on what I saw, there was a possibility that others were involved or Heaton was not involved." Biased procedure? Krane's letter also criticized Allen's technique of laying DNA bands from the crime scene next to Heaton's a procedure that can inject bias. In a 1992 study, the National Research Council recommended that scientists measure DNA bands independently to avoid this bias.

Krane said that Allen's procedural flaw appeared to have affected the test. Allen had to decide which of the DNA markings were definitive enough to be classified as bands and measured by a computer. Allen classified some of the DNA markings that matched Heaton's profile as bands while not classifying other definitive markings that did not match Heaton. Krane believes that because the patterns were laid next to each other, more weight was given to DNA markings shared by the killer and Heaton. "If it was needed to implicate or match, it was called a band.

If it exonerated, it wasn't," Krane said. The decision on which markings to identify as bands was so subjective that Krane doubted that another scientist would have picked out Heaton's bands from the other DNA bands if Allen had not marked Heaton's "bands" with a blue pen. Allen said earlier this month that he was justified in comparing the evidence samples next to each other. "If you were trying to tell two shades of pink from one another, it's easier setting them side-by-side." Krane also criticized the statistical method that Allen used in figuring the 1 in 52,600 odds. i ir 10 1 1 Vaginal swab from crime scene Allen used the "unmodified product rule." Under that rule, a scientist who finds three matching traits each with a 1 in 100 probability would multiply the three probabilities and come up with odds of 1 in a million.

This methods overstates the odds if the three traits often occur together in a population blond hair, blue eyes and fair skin in Scandinavians, for example. Krane said that the more conservative "ceiling principle" is more commonly used since the National Research Council report. Using the ceiling principle, the odds of a match like Heaton's would drop as low as 1 in 1,000, he said. Factoring in the other problems with the way the test was conducted, the odds would dip lower still, Krane said. Most prosecutors say they won't take a case to court without odds of 1 Stanley Hall Charged with Wood's murder lives in a Dallas suburb.

If he murdered Krystal Naab, this band of DNA would be expected to show up in the evidence taken from the scene a spot of semen and a vaginal swab. The DNA from the semen is in the lane above Heaton's and the DNA from the swab is in the lane below.

Dr. Robert Allen, who conducted the test for the state, said he saw bands corresponding to Heaton's in those lanes and marked them with a pen, which shows up as a dot at the top of each lane. Dr. Dan E. Krane, who analyzed the test for the defense, said he didn't see a band at this location, evidence that tends to exonerate Heaton.

Krane said that Allen's test would not hold up under the scrutiny of a Frye hearing, a court proceeding in which lawyers argue the admissibility of scientific evidence. Heaton was denied a Frye hearing, which is the main grounds for his appeal. Heaton, who is in the Menard Correctional Center, said he hopes the court will appoint an independent team of experts to examine the DNA test.

The most intriguing moment in "Bricolage" happens about three-fourths of the way through, when the prevailingly dark mood of both choreography and lighting shifts suddenly to an almost garish brightness.

A more conventional-minded artist might have quit just before this interlude; the pacing certainly suggests it is time to wrap things up, and after a long series of duos and trios, the quiet frieze into whfth the dancers settle seems like a conclusive image. By violating viewers' expectations, Grace perhaps quadruples the psychological resonance of her piece. Eventually a finale does come, different in tone from the false ending but choreographically just as logical. It is not, however, an obvious finale to which "meaning" can readily be attached; "Bricolage" ends more or less where it began, and in its circular structure lies mysterious beauty.

Police arrested 'Heaton, a self-employed carpenter 'who owned a white truck. fingerprints, hairs, fibers or blood linked Heaton to the crime. But Allen concluded that the genetic material in semen found at the crime scene matched the genetic material 'irt' Heaton's blood. The chances of a match like that occurring randomly were one in 52,600, he said.

''i1 The genetic test was the linchpin Of the prosecution case and is the main target of an appeal seeking to overturn Heaton's conviction. At a state appeals court hearing 1 i 8 jlier this month, Heaton's lawyer, 1 9 Michelle Malinowski of Chicago, argued that Heaton should have been granted a hearing to determine the pliability of the test. 1 year ago, Malinowski asked Krane to analyze Allen's test. Krane gave his conclusions in a two-page letter but asked that it not be made 1 public because of his professional re-- 'lationship as a co-author with Allen, i Krane agreed to disclose his conclusions after a recent article in the Post-Dispatch reported lingering questions about Heaton's guilt. DNA testing Genetic tests analyze patterns or of DNA deoxyribonucleic acid.

By comparing the bands in the suspect's genetic pattern to the bands from a crime scene, scientists determine whether the samples "match." Allen testified that four bands from Heaton's blood matched bands in se-" nien found at the crime scene. Krane agreed that there were 1 "matches." But his analysis of four of the state's exhibits Exhibits and differs from Allen's. Allen had found Exhibit inconclusive because Heaton and Naab shared the part of the genetic structure analyzed in that exhibit. But Krane said the exhibit appears to show that Heaton has a band that was not present at the crime scene. "If a suspect clearly has a band that is not seen in the evidence sample, a strong case could be made for exclusion," Krane wrote in his letter.

Heaton's band is identified as a "2.38 kb band," meaning that it is a sequence with 2,380 rungs on the DNA ladder. Krane thinks that Allen disregarded this band because Naab had a 2.33 kb band, which is close to the same length. But Krane said that the genetic test should have been accurate enough to distinguish a 2.38 kb band from a 2.33 kb band, i Exhibit also tends to exonerate Heaton, Krane said. Allen maintained that Heaton's DNA bands showed up in the evidence. But pictures of the evidence indicate that Heaton's 5.51 kb band did not show up in the evi Here are five suggestions for avoiding trouble in parking lots: When driving or stopped, look around and be aware of your surroundings.

If something looks suspicious, have an escape route in mind and drive away. Keep your car doors locked with the windows rolled up. This keeps criminals from reaching in and taking your car keys, purse or other belongings. Park in a well-lighted area, as close to the shop's doors or other drivers as possible. Before you unlock your door and get out, see who is nearby.

Take that extra second to look around. If someone with a weapon demands your car, comply.

At its fastest, the wind reached 66 mph about 12:30 a.m., said Dan Ferry, a meteorologist with the National Weather Service.

The wind was a companion to a line of showers that passed through the area late Saturday and early Sunday, he said. The wind packed a punch. It broke windows in about 40 new vans parked outside the Chrysler Motors plant in Fenton, said P.H. Martin, a fire and security officer at the plant. PER M0.
