BALTIMORE (AP) -- Police searched parks on foot and sent a robot into underground storm drains in their efforts to find a fugitive accused of killing four people in a two-day rampage.
But Joseph Palczynski on Monday eluded police for a sixth day. Police believe he may be using the pipes to travel to railroad tracks and a neighborhood 7-Eleven store, where there have been unconfirmed sightings.
Police believe bedding and clothing found in woods in the area may have been used by Palczynski.
A line of 60 police officers marched across Dundee Salt Peter Park Monday morning and nearby Gunpowder Falls State Park in the afternoon, in the hopes of flushing him out. Police would not say what led them to the parks.
''Nothing and no one has been found,'' police spokesman Bill Toohey said.
Authorities say Palczynski abducted his estranged girlfriend March 7 after shooting to death a couple who had sheltered her after she moved from his home, then killed a neighbor. He allegedly killed a fourth person the next day.
