Chicago Shootings over Weekend
In just a three-day span, at least seven people were killed and at least 46 people were shot. Chicago police were involved in three of those shootings.
Most recently, police officers shot and killed Westley, who they say pointed a weapon at officers near 66th Street and Sangamon. Police say they heard shots fired and saw three people running from the area, including Westley.
As police tried to arrest him, they say Westley pointed a gun at officers. So, they fired at him. Westley was killed.
"I've never known Mikey to be involved in any gang or have any guns or anything like that," said relative Eastley Lewis.
However, police say they recovered two guns at the scene. Westley would have been a high school sophomore at TEAM Englewood this fall.
"He loved to play basketball. He loved to play football. He was good kid -- just loved to play sports," friend Darrell Holmes.
The shooting wrapped up a challenging few days for Chicago police. Despite the shootings, Chicago police say the violence is decreasing. The police department released statistics that show 31 percent fewer murders were reported, 27 fewer shootings and 14 percent fewer overall crime incidents in 2013, compared to the same time period in 2012.
Police Supt. Garry McCarthy has said in the past that the drop is progress, not victory.
