On the morning of May 23, 1903, ten picked detectives were secured
from the Detective Bureau to accompany Wooldridge in the raid on
George T. Sullivan, which turned out to be one of the largest as well
as one of the most sensational raids and arrests that had occurred in
Chicago for years.
Sullivan did an extensive business. The offices of the company which
were raided were elaborately furnished, and there was a complete
assortment of tickers, blackboards and like paraphernalia. At the time
of the raid the offices were crowded, the operations on the open board
and the Board of Trade being remarkably exciting. The officers who
assisted Wooldridge in the raid were Detective Sergeants Howe, Mullen,
Quinn, Qualey, Miskel, McLaughlin, Weber, Flint and McLane.
