* In March, armed with evidence that a drug dealer had been killed with a single gunshot during a robbery by two men, Torrance, Calif., district attorney Todd D. Rubenstein obtained separate jury convictions of both men for firing the fatal shot. Both robbers' guns had fired, but one missed, and a conclusion as to which one could not be drawn from ballistics tests. Rubenstein asserted confidently to one jury that Stephen Edmond Davis, 19, shot the man, and just as confidently to the other jury that it wasn't Davis, but rather John Patrick Winkleman, 19. * Former Prestonburg, Ky., school board member Wood R. Keesee, 59, filed a lawsuit in May against a female court clerk to whom he had allegedly loaned money in 1996. Under the terms of the $1,800 loan, according to Keesee, she was to have 18 sexual encounters with him, but when she stopped after three, he filed the lawsuit.
