FORENSIC ASTRONOMY by Jeffrey Dobereiner

In a historic Omaha court case, astronomical evidence played a key role in foiling an attempt
to frame a man for attempted murder.

Shadow of a Doubt


tpA 1910 trial in Omaha, Nebras-
ka, hinged on two girls who saw a
man matching the description of
the accused carrying a suitcase
bomb on their way home from
church, where they had been pho-
tographed after a confi rmation cer-
emony. William Rigge, astronomer
at Creighton University, invalidated
their testimony by analyzing the
shadows in the photo and proving
that it had been taken a half hour
after the bomb was discovered.
Rigge (in foreground, with watch)
reenacted the scene precisely two
years after the fi rst photo, showing
the shadow in the same location.
