At Wasni's initial court hearing in Cook County on Wednesday, authorities said she stabbed Nelson multiple times. He ran to a nearby building seeking help and she tried to drive off in his car but then fled on foot after striking a median, prosecutors said. She was located nearby a short time later, still holding the knife and machete; a blood-stained Cubs shirt she had been seen wearing in Walmart surveillance video also was found nearby, they said. Nelson was able to describe his attacker before he died, authorities said.
