Possible meteorite hit?

I just received an e-mail (11:30 am EST 12/22/08) from my friends at
Kopernik Observatory (www.kopernik.org) asking for help examining a possible
meteorite fall from a few hours ago. My question is: How do you tell a
meteorite from some other falling object? Other than checking for burn
evidence, magnetic and metallic properties and possible radioactivity, what
else should we check to determine what this "rock" is?



Here's want I know so far:



"We just got a call from emergency services in Port Crane, New York. He said
this morning a couple (names deleted) were eating breakfast and a loud crash
sent them to their garage, where they say a big rock had crashed thru the
window and made a hole in the concrete floor. The owner said the angle of
trajectory was such that it couldn't have come from Earth, and saw no
footprints or other signs nearby."
