Copyright (c) 1996, Dayton Newspapers Inc.DATE: Wednesday, February 14, 1996           TAG: 9602140244EDITION: CITY           SECTION: METRO TODAY PAGE: 1B SOURCE: By Janice Haidet Morse        DAYTON DAILY NEWS                          BROTHERS DIDN'T KNOW PAIR   Two witnesses who testified against Jenny Wilcox and Robert Aldridge 11 years ago say they didnt even know the couple - and were able to single out them in a courtroom only because prosecutors previously had shown them where Wilcox and Aldridge would be seated.   John Chronopoulos, now 23, and his brother, Jason, now 21, testified Tuesday in Montgomery County Common Pleas Court that Wilcox and Aldridge neverhad sex with them, never threatened them, never pulled a knife on them - contradicting testimony they gave when they were children.   "I'd never even seen these people before in my life until that day in court," said Jason Chronopoulos, recalling the 1985 trial that sent the coupleto prison for life on multiple rape and sex abuse charges.   The Chronopouloses said they were scared little boys who felt pressured into giving false statements against Wilcox and Aldridge. They also said they had been the subject of wild rumors alleging sexual deviance in the summer of 1984 - until blame was deflected to Wilcox and Aldridge.   The Chronopouloses were among the first witnesses to testify in a hearing where defense lawyers are arguing that the couples convictions should be voided. Today their younger brother, Justin, also is expected to testify.   Prosecutors wanted the hearing closed to the media, which visiting Judge Richard E. Parrott refused to do.   Expected to last four days, the hearing will focus on three major points:   *Possible prosecutorial misconduct. The couple's original lawyers never received a 29-page police report that contains information telling how witnesses' stories changed throughout the investigation, the couple's new defense lawyers allege. Instead, the defense was given an  eight-page "sanitized" report lacking evidence that would seem to exonerate Wilcox and Aldridge. Defense lawyers also allege that other evidence favorable to Wilcox and Aldridge was "intentionally suppressed."    Two assistant county prosecutors now assigned to the case, Linda Howland and Raymond Dundes, declined to comment Tuesday.   *Ineffective defense lawyers.  The couple's original lawyers spent a total of six hours preparing for the case, according to fee statements obtained by the current lawyers. The original lawyers also failed to investigate medical records that would show no evidence of the alleged rapes, said Harry Reinhart of Columbus, one of four defense lawyers now working on the case.   *"Wildly coercive" police interrogation techniques that are inappropriate for use with children. Reinhart said experts will testify about the psychologyof coercion and why certain interview techniques are improper to use with children.   In the summer of 1994, when they were about 11, 10 and 7 years old, John, Jason and Justin Chronopoulos were accused of raping a little girl who lived in their apartment complex. When questioned by a Huber Heights police detective, John denied any sexual activity. But then he was handcuffed, charged with rape and placed in juvenile detention.   "I'd never been away from my mom and I was scared . . . I wanted to get out," he testified Tuesday. John said that, based on the way the detective questioned him, he thought he was supposed to say he was involved in some sexual activity - so he changed his story. Then he was released from detention.   Asked how he knew to identify Wilcox and Aldridge as the perpetrators, Johnsaid he was shown a photo spread that included their pictures and was told that these were the two people that other children were talking about. "I never met them . . . I never knew who they were . . . I didn't know their names," John said. "Those were the names we were supposed to say had done it, so we all just stuck to it."
