A security firm is warning that the person who mailed non-working letter bombs to Denver-based Janus Capital and other money management firms earlier this year may soon escalate his tactics, including targeting industry executives at home.
The mailer, who identifies himself as “The Bishop,” appears to have studied the pattern set by the “Unabomber,” according to an alert sent out by Fred Burton with Strategic Forecasting in Austin, Texas.
Theodore Kaczynski, the Unabomber, first came to the attention of authorities in 1978, but it wasn’t until 1980 that he sent a working explosive device to the home of United Airlines CEO Percy Woods.
“We expect the risks to financial-services workers to tick upward yet again unless he is apprehended,” Burton wrote of the Bishop.
The package from the Bishop was addressed to Janus Small Cap in Denver. It was forwarded on to Chicago-based Perkins Wolf McDonnell, a money management firm which oversees the Janus Small Cap Value Fund for Janus.
“We called the proper authorities. They have been handling the investigation,” said Janus spokeswoman Shelley Peterson.
