A days-long manhunt for two escaped killers prompted a burst of police activity on Tuesday as investigators converged on an upstate town about an hour from the prison where the men had been incarcerated.
The prisoners, Richard W. Matt and David Sweat, were discovered missing from their cells at 5:30 a.m. on Saturday at Clinton Correctional Facility in Dannemora, N.Y., 25 miles from the Canadian border.
