Sunday marks 10 years since the worst nightclub disaster in Chicago history.

Some of the families of the 21 victims of the E2 nightclub stampede held a memorial service at 2:30 Sunday morning — the approximate time when the tragedy took place on February 17th, 2003.

A carpenter, Greg Zanis, donated handmade crosses for the families to place outside the shuttered club.

12-year-old Shawnice Brown was among the mourners.

She was only two years old when her father died in the stampede.

The club was packed with more than 1,100 people that night.

Witnesses say a brawl on the second floor caused security guards to use pepper spray.

People swarmed the exits, to escape the noxious gas.

21 people were either smothered or trampled.

Many of the victims’ families say the club’s inward-opening doors caused people to be trapped inside.

The club’s owners have never been found guilty of criminal wrongdoing.
