2 - The Michigan Daily - Thursday,M 3 March 34, 1995 Y=RAPIST Continued from page 1 blood and hair taken on Dec. 27 and consented only when Pressley called several more law enforcement officers to the Washtenaw County Jail where Mitchell has been since his arrest. "DNA is basically the blueprint of all life," Dr. Stephen Milligan of the State Police Crime Lab's DNA unit said yesterday. "Ninety-nine percent of our DNA is the same from person to person. That 1 percent (which de- termines traits like eye color) is what we focus on." Technicians use probes of DNA to break the sample down into compa- rable parts. The more probes or sec- tions that are compared, the greater the likelihood that a match is not due to random chance. DNA experts also testified that they used the "ceiling principle," which was described as an "extremely conservative" method of calculating the odds of a match. In addition, the DNA experts used an artificially im- posed "95 percent confidence inter- val" to work in the defendant's favor. Regarding the rape and murder of University employee Christine Gailbreath on May 7, 1994, Milligan said, "At this time there is a five- probe match between known blood samples of Ervin Mitchell and the samples of vaginal swabs taken from Christine Gailbreath." Milligan testified that there was a six-probe match between DNA evi- dence in a Sept. 28, 1992, rape occur- ring in Eberwhite Woods on the city's west side. "I can't even comprehend that one would ever see that by chance," Milligan said. "For a six-probe match to Ervin Mitchell's known blood sample, in the Caucasian population, you would see it one time in 7.8 tril- lion individuals. In the Black popula- tion, it would be one in one trillion. These are all estimates." These estimates, however, could prove troublesome for Mitchell. Lankford attempted to discredit the DNA experts' testimony by criticiz- ing the small sample size of the gen- eral population used to determine the probability that a match is random. The State Police Crime Lab com- pared certain genetic markers and the frequency with which they would appear in any given population of three different ethnic groups - Cau- casian, Blacks and Hispanics. There were 400 Caucasian individuals, 500 Black individuals and 300 Hispanic individuals in the lab's sample group. Dr. Julie Howenstein, also from the lab's DNA unit, testified that there was a five-probe match of semen evi- dence from the Oct. 2, 1993 rape of a University student and DNA found in Mitchell's blood samples. She said the chance that the semen came from a person other than Mitchell was 1 in 8 million. In the National Science Foundation's opinion, Milligan testi- fied, that a 3-5 match probe is strong evidence that the samples came from the same source. The DNA testimony concerned Lankford so much that his objections caused the judge to meet him and Mackie in her chambers for more than an hour. Lankford called none of his own witnesses to the stand during the three-day examination of nearly 22 prosecution witnesses. Lankford during his cross-examination asked if there was enough of the DNA evidence left to conduct independent tests. Mitchell's attorney also accused the prosecution of withholding infor- mation regarding the DNA analysis. Thejudge dismissed such accusations. "It is clear to me that the prosecu- tion is not withholding anything from the defense," Mattson said. "This is a probable cause hearing. The court feels there is an adequate basis to continue its cross-examination." Mattson decided yesterday to re- convene the examination today at 9 a.m. to allow legal counsel to present final arguments before ruling whether Mitchell will be held over for trial. & NATIONAL EPOR T Clinton defends his economic record ATLANTA - President Clinton, presiding at an economic conference in a region where he is politically vulnerable, conceded yesterday that worker discontent lurks beneath generally upbeat statistics. But he defended his policies, his priorities and his presi- dency, telling handpicked participants from 12 Southern states, "There is a lot more room for hope than for doubt." Speaking at Emory University, the alma mater of House Speaker Newt Gingrich (R-Ga.), Clinton said he felt "a responsibility to try to keep this economic recovery going." The daylong conference was the first of four the White House plans around the country. Conferences, speeches and other appearances over the next few months will take Clinton to crucial 1996 battle- Clinton ground states: Georgia, Florida, California, Iowa, New Hampshire and Michigan. While publicly denying political motivations, White House aides and Demo- cratic advisers said they hoped for a lot of mileage out of the exposure. Late last night in Tallahassee, Fla., for instance, Clinton was expected to* announce good economic news for the state: that the Pentagon would relocate its Southern Command - now based in Panama - to Florida. great scores..

Congressional panel suggests D.C. overhaul WASHINGTON - A congres- sional panel yesterday recommended the strictest financial controls ever de- vised for a U.S. city be imposed on the District of Columbia, a step members said was needed to rehabilitate the "tar- nished" image of the nation's capital. In a unanimous vote, the House District subcommittee moved to create a presidentially appointed board to re- order the District's finances and re- structure its government. The bill also calls for a new chief financial officer who Mayor Marion Barry acknowl- edged would have more "responsibil- ity" over the government than he does. Quick follow-up votes in the House and Senate are planned for the mea- sure, and the board could begin issuing directives on the city budget to the mayor, D.C. Council and other local officials by mid-June. The five-mem- ber panel would assume authority over city spending levels and borrowing within a matter of weeks. The board could extend into the next centgry. President Clinton praised the legis- lation as a rare example of bipartisan cooperation needed to rescue a na- tional asset. Computer helps to find breast cancer tumors NEW ORLEANS - A newly de- veloped computermay find as many as half the breast cancer malignancies doctors miss reading mammograms. "It's like a second opinion," said Dr. Maryellen Giger of the University of Chicago, one of the developers. She discussed the development yesterday at an American Cancer Society confer- ence. The computer - called an intelli- gent mammography workstation-has been used to analyze more than 1,000 breast X-rays since November and will be put into regular use on an experi- mental basis at the University of Chi- cago next month. great sls..

Yeltsin has abandoned his cross-country journey to retreat to a secluded state dacha, his advisers dis- closed yesterday, scrapping what was to have been a two-week tour of the provinces aimed at getting in touch with the people. Yeltsin will remain at the walled, heavily guarded compound outside the southern city of Kislovodsk for the rest of his spring vacation, the official Itar- Tass news agency reported from the spa region quoting "sources close to the president." The sudden change in plans - at least the third departure from the an- nounced schedule since the trip began three days ago - stirred speculation about Yeltsin's health, as he appeared weak and disoriented Monday during the one whistle-stop he went through with, a short visit to the city of Ryazan. But after the highly orchestrated Ryazan visit, he left the train behind and flew with his security entourage to Kislovodsk. Yeltsin aide Sergei V. Svistunov brushed off suggestions the change of plans was anything more than the pre- rogative of a busy man taking time off work. "This does not mean he has rejected the idea of meeting common people in the street. He may do this later," Svistunov said. 3 killed in Gaza Strip confrontation JERUSALEM-Two Israelis and a Palestinian were killed yesterday in what Israel said was a Palestinian at- tack on an Israeli convoy escorting Jewish settlers to the isolated settle- ment of Netzarim in the Palestinian- controlled Gaza Strip. An armed Palestinian rammed his* truck into ajeep carrying border police and police near Netzarim, on a road controlled by Israeli forces, Police Minister Moshe Shahal said. Shahal told the Knesset, Israel's Parliament, that the Palestinian leaped from his truck after the crash, then opened fire on the convoy before he was gunned down by an Israeli Army officer and a settler. A border policeman and another police officer were killed; two others were seriously injured, Shahal reported. He said it was not known whether the Israelis were killed by the impact, orby the shooting that followed. /tN WFaN0Qr j 4 ,tNttld Fl tNe cfl e2My MIX I lN/pre e M21 t2 a, guy U/2 tN /e ND tfl ttef lflate ex 2Dr t0 Cete Get fie e /S ODesM 1 - From Daily wire services IC L A ,2 A The Michigan Daily (ISSN 0745-967) is published Monday through Friday during the fall and winter terms by students at the University of Michigan.
