In Harrisburg, a prosecutor says authorities are still investigating the motives of an armed man who shot at police in several locations before dying in a shootout. Dauphin County District Attorney Ed Marsico gave no new information yesterday about Ahmed El-Mofty. The 51-year-old naturalized citizen fired at a Capitol police officer Friday afternoon and later at a state trooper, wounding her. El-Mofty was later killed in a confrontation with police.
