Authorities are questioning three suspects accused of breaking into the victims' home and shooting them. Police say they wore masks.
The murdered teen's mother is listed in critical condition at Illinois Masonic Hospital. Her son, Andre Vasquez, died. The attack happened at their home in the 3400 block of Lawndale in the Avondale neighborhood before 9 a.m.
Authorities say a 14-year-old girl, Vasquez's sister, was in the home and managed to escape the attack.
Police recovered a gun in the 3400 block of W. Wilson and evidence in the alley of the 3100 block of Wilson. Authorities took possession of the suspects' vehicle a few blocks away from the scene.
"I got a call saying Crystal and Andre been shot, and we went to the hospital and it's true, Andre and Crystal both been shot. I guess they was taken to the basement apartment, shot by two guys that came in with masks. They both shot in the head," said Antonio, a relative of the victim who did not want to give his last name. "It is still a shock for me."
The victims' relative says the mother and son lived on the first floor home for a year and a half. The house is across the street from an elementary school and a church. Residents say the neighborhood is a safe community filled with children.
Another elementary school is located a block away from the scene. Parents are concerned.
A family member says Vasquez attended Schurz High School where he got As and Bs.
