Charges have been filed against a teenager suspected of firing the shot that killed 11-year-old Shamiya Adams.
Chicago Police Superintendent Garry McCarthy said police arrested Tevin Lee, 18, on Tuesday. But the charges, including murder, did not come down until late Wednesday.
Lee is a known gang member and police are confident he is the one who pulled the trigger.
Shamiya Adams was killed by a stray bullet that went through the window of an East Garfield Park apartment building last Friday while she was there for a slumber party.
Police say it all started Friday afternoon when two 14-year-olds got into a fist fight. Then about six or seven hours later police say Lee came back, thought he saw rival gang members involved in that fight, and opened fire in retaliation.
"A couple of 14-year-olds get into a fight, somebody introduces a gun into the situation and we now have another child murdered," McCarthy said. "This is a pattern that we have to break."
McCarthy told reporters it was great cooperation with people in the neighborhood that helped police make the arrest. He said they had nine great witnesses in the case.
The Superintendent also said he hoped that Shamiya Adams' family gets some justice out of this arrest and some closure.
