After at least 50 people were killed and 53 were injured in a mass shooting that targeted LGBT people in Orlando early Sunday morning, Chicagoans honored the victims as police stepped up security around the city “out of an abundance of caution.” Hundreds of people gathered for a vigil to mourn in the Boystown neighborhood Sunday evening.

  •    Pat Quinn returns to the political scene with petition for mayoral term limits

Ex-governor Pat Quinn has remained largely out of the spotlight since he lost to Governor Bruce Rauner in 2014. But he returned to public life Sunday to launch campaign for a two-term limit for Chicago mayors and an elected consumer advocate position for the city. Although Quinn says that the petition isn’t aimed at a specific person, the referendum could be on the ballot before the next mayoral election in 2019, and if it passes, Mayor Rahm Emanuel would be ineligible to run again.

  •      Chicago Police destroyed suicide victim’s last notes to her parents

The family of 29-year-old Nicole Porter, who ended her own life in 2015, is highly upset that the Chicago Police Department accidentally destroyed the two final letters she left her parents. The police took the last messages as evidence from Porter’s apartment but promised her parents that they could get them back at the end of the investigation. Destroying the letters before her parents could pick them up was “an administrative error” for which the department is “deeply sorry,” police spokesman Anthony Guglielmi told the Washington Post.

  •      Four years later, the mystery of the poisoned local lotto winner remains open

A few years ago, the death and subsequent exhumation of recent lottery winner Urooj Khan drew attention around the globe. Investigators determined after Khan’s body was exhumed that he had been poisoned with cyanide. Yet the rampant media attention didn’t solve the puzzling case, and the family is still at square one. Khan’s sister told the Associated Press that the Chicago Police haven’t done anything to solve the mystery, despite the department’s recent statement that it’s a open and active case.
