The 1961, trial of Chester Weger was the first case for then-26-year-old prosecutor Anthony Raccuglia.

“If they let that man loose, every person that investigated this case, every lawyer that assisted in the trial, the judge, the witnesses — over 100 witnesses — will all roll over in their grave,” says Raccuglia, now 83, tells WBBM’s Steve Miller.

That would be juror Nancy Porter, who is 92.

“He should’ve been freed a long time ago, as far as I’m concerned,” she says.

Porter now thinks Weger is innocent. She believes Weger was too small a man to have killed the three women.
