It's been a violent holiday weekend in several Chicago neighborhoods.
At least 11 people are dead and more than 50 people are injured in shootings since Thursday night.
One shooting overnight left a woman dead near west 109th and Throop.
The 44 year old woman may have been attending a barbeque nearby when she was shot.
Her name hasn't been released and there's no information yet about what circumstances led to the shooting.
Three people were shot about a half an hour earlier. Someone fired toward a man and a woman who were coming out of a store near 81st and Exchange. The man was hit in the head and his hospitalized in critical condition. The woman was shot in the thigh and is in stable condition.
Another man nearby was shot while he was sitting on a porch at 80th and Escanada. Police have made no arrests in these shootings.
Several of those shootings were police involved, two of which were fatal.
Officers were called to Sangamon and 87th streets around 6:30 p.m., with reports that someone was firing a gun in the area.
Fraternal Order of Police spokesman Pat Camden says the 16-year-old, who is identified by family as Warren Robinson, matched the description they had of the person firing shots. The teen ran when officers arrived, then tried to blend into a party before police finally caught up with him while he was hiding under a car.
Camden says Robinson had a gun, and his finger was on the trigger. He says officers shot Robinson after the teen repeatedly ignored their demands to put it down. The gun was recovered at the scene.
And Friday, police shot and killed a 14-year-old Pedro Rios in the Portage Park neighborhood.
Rios took off running when police tried to stop him after seeing that he had a gun. Officers opened fire when they say he pointed "a large revolver" at them.
The second person shot by police Saturday night was wounded in the buttocks about 9 p.m. in the 7000 block of South Hermitage Avenue.
Officers tried to interview people drinking on a porch when a man took off running and officers gave chase, police said in a statement. The man pulled a gun from his waistband while he was running.
Police opened fire after the man turned toward them and pointed the gun. He was taken to the hospital with non life-threatening injuries.
Most of the shootings happened on the South and West Side of Chicago. Four of them happened on the North Side. One of the shootings just a few blocks from where Mayor Rahm Emanuel lives.
Mayor Emanuel has not yet commented on the weekend's violence.
Police Superintendent Garry McCarthy released a statement saying the department plans to keep building on their strategy to put more officers on the street in summer months. McCarthy also says police are facing an uphill battle until federal laws to keep guns off the streets change.
Superintendent McCarthy is expected to address the violence in a press conference later today.
