Law enforcement officials said a relative, called in for questioning, admitted purchasing a bus ticket for Lewis on Saturday. They believe Lewis would have arrived in Florida late Sunday.
The rapidly expanding investigation leaped forward yesterday afternoon when police recovered two handguns that they say link Lewis to the murder.
One was the officer's 9mm Glock semiautomatic, stolen immediately after he was gunned down. The second firearm may be the murder weapon. Analysts were conducting a ballistics test on it last night.
Both handguns were taken from a house in the 3800 block of North Franklin Street, the residence of an associate of Lewis'.
The recovery of two handguns added weight to the evidence against Lewis. Johnson said there was "no doubt" that investigators were looking for the right man.
Before he fled, Lewis told family members he would not surrender, according to a federal warrant issued for his arrest early Sunday. "Lewis expressed a desire not to be captured," the warrant stated.
The affidavit also stated that Lewis confessed to his family.
Cassidy, 54, was shot Wednesday morning after he interrupted an armed robbery at a Dunkin' Donuts in West Oak Lane. Police said the surprised assailant wheeled and shot Cassidy in the head from five feet away.
A law enforcement source said last night that the second handgun recovered yesterday was not the firearm reported missing by Lewis' mother, Lynn Dyches, a corrections officer in the Philadelphia Prison System. Police initially suspected that her gun might have been used in the murder.
