suspect, Maine residents shelter behind locked

Our manhunts take longer these days, don't they? I'm thinking of course of the Pennsylvania murder escapee. Why did the gendarme spend so much time, personnel, and resources at a house where this suspect was not?

Much of Thursday’s search focused on a large property belonging to one of Card’s relatives in rural Bowdoin, where trucks and vans full of armed agents from the FBI and other agencies eventually surrounded a home on Thursday.

Authorities repeatedly yelled for Card and anyone else inside the home to surrender. But hours later, they left, with state police saying it was unclear whether the suspect had ever been at the location.

In many past U.S. mass shootings, the suspect was found — whether dead or alive — within minutes. But Card was still on the loose more than a full day after the shootings.
