It took two weeks of testimony but only two hours of deliberations Wednesday for a LaSalle County jury to find a Seneca man guilty of murdering a Normal woman's parents in July 2007. After two weeks of testimony, a jury of seven men and five women took just two hours to reach its decision in the Keith Mackowiak case. He was charged with the murders of Aloysis and Catherine Twardowski of rural Seneca. They were found slain in their home following a burglary. Because the case involved two murders, Mackowiak is expected to face a life sentence when he's sentenced in April.
