If you were to tell me the Federal Bureau of Investigation had a file on Mykel Board, Christopher X. Brodeur or even Steve Nash, I might believe it. However, until reading the below item, I wasn’t aware the late Cubs 3B / broadcaster Ron Santo was once the subject of such a file, presumably due to death threats made against him in 1970 more than any insurrectionist activities.  USA Today’s Peter Eisler learned the following, thanks to the Freedom Of Information Act.

In mid-summer 1972, Santo began receiving a series of threatening letters at home, one of which contained words pasted from a newspaper to read “two girls one man dead.” Two fans of Santo, 15-year-old girls, also received threatening letters and reported receiving telephone calls, according to the file.

Santo, who lived in Glenville, Ill., at the time, received protection from the Glenville police department, the file says. In the fall of 1972, the letter writer suggested meeting with Santo, so FBI officers posing as Santo drove the player’s car to the location under a stakeout, but were unable to make contact.

While Santo received no letters after the 1972 season, the FBI continued to investigate the incident for more than two years. At one point, they obtained handwriting samples of the two fans, including samples of their school work obtained from the principal of their high school, the file says. While one analysis of samples found “numerous similarities to some of the handwriting in extortion letters,” the FBI ultimately found “a definitive conclusion could not be reached” as to whether they matched the handwriting from the threatening letters, according to the file. (Names of all principals in the case besides Santo were redacted from the FBI files).
