• Remembering the victims of one of Chicago's most infamous murders

The murder of eight student nurses from South Chicago Community Hospital by Richard Speck in July 1966 had such a big impact on American pop culture that it's been referenced on television shows ranging from Mad Men to American Horror Story to Chicago PD. Now, 50 years later, the Tribune has conducted rare interviews with victims' families and friends. The results are a fascinating look into the lives of young women who were overshadowed by their infamous killer. [Tribune]

• Don't count on seeing the NFL draft here next year
  This week might be your last chance for a while to see the NFL draft take over Grant Park. Polarizing NFL Commissioner Roger Goodell said it's "very likely" that the draft will move to a different city for 2017, even though the NFL's getting a sweet deal on Grant Park. The league's set to pay about $103,000 for renting it, even though the estimated value of the rental is $3.2 million. [Sun-Times] [DNAinfo Chicago]

• Clean-food start-ups cleaning up in Chicago market

Several Chicago-based start-ups are at the forefront of the "clean eating" trend. According to Crain's, brands like Kitchfix (which now has a storefront in the Gold Coast), RXBar, and Simple Mills are expanding their healthy-food empires by focusing on "real" "whole foods" and avoiding artificial ingredients in their packaged and frozen food offerings. It doesn't come cheap: Kitchfix sells a package of four frozen grain-free waffles for $9.99. The popularity of so-called clean foods has forced the giants like Deerfield-based Mondelez International to compete by ceasing the use of artificial colors and flavors in its packaged goods.
