( CNN ) -- A man named as a suspect in the fatal shooting of a Philadelphia , Pennsylvania , police officer last week was captured at a shelter in Miami , Florida , on Tuesday , Philadelphia Police Commissioner Sylvester Johnson said at a news conference . Miami Police Chief John Timoney said he had been alerted by Philadelphia police that the suspect , John Lewis , had taken a Miami-bound bus from Philadelphia . Acting on information from Miami Rescue Mission , officers went to a homeless shelter where they found Lewis , `` who was pretty easy to spot as he 's 6 feet , 270 pounds , '' Timoney said . He was apprehended `` unarmed and without incident , '' the Miami chief said . Timoney said it did n't appear that anyone in Miami was helping Lewis , according to CNN affiliate WPVI . Miami Police Officer Gil Gonzalez said Lewis `` had a Bible and was praying when we went to get him . He had a look of guilt , a look of shock . '' Philadelphia Mayor John F. Street said people at the shelter recognized Lewis from televised photos of the suspect . Lewis is suspected in the October 31 shooting of Philadelphia Police Officer Chuck Cassidy . Cassidy was shot in the head when he inadvertently walked into a robbery in progress at a Dunkin ' Donuts . He died the next day . Investigators told WPVI that Lewis was spotted on security video boarding a bus to Miami on Saturday night . Cassidy was one of three Philadelphia police officers shot in a four-day period last week . Mariano Santiago was shot in the shoulder late last Tuesday as he approached a vehicle . He is in fair condition . Officer Sandra VanHinkle was shot early last Sunday and is out of the hospital and doing well , police say . Former co-workers of Lewis who spoke to WPVI said they were surprised by the allegations against him . `` He was so nice , '' Kiani Clark told the station . `` He was really nice . He did n't seem like the type that would hurt a fly . '' The Associated Press reported that Lewis had been arrested in 2005 on drug charges , which were withdrawn after he completed a treatment program . He was arrested again in June on drug charges , and that case is still pending , the AP reported . E-mail to a friend . CNN 's Aurore Ankarcrona contributed to this report . Copyright 2007 CNN .
