But as Friday turned into Saturday, exhausted detectives headed home for breaks from their 18-hour shifts. Johnson was less sanguine about quick results: "Things that look promising don't always pan out," he said.
The weekend continued as an emotional roller coaster in the massive manhunt for the tattooed suspect who shot Cassidy in the head after the 25-year veteran interrupted an armed robbery at the Dunkin' Donuts at 6620 N. Broad St.
At an interdenominational prayer service Friday in City Hall, Mayor Street said the city was under "psychological, emotional and spiritual" stress. Cassidy was the third officer shot this week.
At a police promotions ceremony at Temple University, also on Friday, the celebration took on a somber tone as officers expressed a desire to get back on the streets to hunt down Cassidy's killer.
And the West Oak Lane neighborhood where Cassidy was gunned down, the frenzied activities by police the two previous days was replaced by a subdued calm. The only difference from the usual were four TV news vans parked outside the Dunkin' Donuts where the officer was shot.
Cassidy, 54, died Thursday at Albert Einstein Medical Center. Yesterday, his body was carried in a hearse escorted by dozens of police vehicles to a funeral home in Northeast Philadelphia, where he lived with his wife and three children. The motorcade, accompanied by a police helicopter, shut down traffic on I-95.
Investigators have been pursuing numerous leads that poured in throughout the past few days. Officials announced that the reward for Cassidy's killer had increased to $152,000.
Johnson said investigators have conducted an "enormous" number of interviews. Homicide detectives have moved into a special command room on the third floor of police headquarters to coordinate the investigation. They are assisted by officers from federal law-enforcement agencies.
