A report the day after the crash from The Chicago Tribune reported that county officers had “believed that one of many motors or a gasoline tank blew up.” Nonetheless, a brand new idea quickly emerged: that the airplane had been introduced down by a time bomb (by way of Chicago).
This idea was initially denied by federal investigators working for the Division of Commerce, as this incident predated the Federal Aviation Administration, however it was championed by Porter County Coroner, Dr. Carl Davis who stated that “bits of bags had been discovered riddled and torn as if broken by an explosion of nice pressure.”
In accordance with NBC Chicago, one of many FBI brokers assigned to analyze the crash was Melvin Purvis. Not even a yr later, he could be current for the shootout that might result in the demise of famed financial institution robber John Dillinger outdoors of the Biograph Theater.
In late 1935, FBI director J. Edgar Hoover ordered the Bureau’s Chicago workplace to shut the case, regardless of no definitive conclusion being reached.
The primary suspect to emerge was passenger Emil Smith. A baggage porter had reported Smith resulting from his uncommon conduct which included bringing a small-bore rifle and ammo onto the airplane, and his particularity in regards to the dealing with of a brown paper-covered package deal. Nonetheless, it seems that Smith was going to Chicago for a contest at a taking pictures membership, and the package deal was recovered on the crash website.
