Church's Chicken Shooting: Suspect In Custody In Incident That Killed 2, Injured 5 In Chicago (VIDEO)

Chicago police reportedly have a suspect in custody in connection with the Tuesday shooting at a South Side Church's Chicken restaurant that left two dead and five others injured.

NBC Chicago reports that police have focused their investigation on two suspects, including a 23-year-old individual whom they are currently questioning but has not yet been charged. The other suspect reportedly remains on the run. Chicago police declined to confirm the reports.

Killed in the shooting were Jawan Ross, 16, and Dantril Brown, 17. Both teens were inside the Church's Chicken, located at 66th and Halsted streets, around 6:50 p.m. Tuesday, when a man apparently became involved in an argument with someone outside of the eatery before he chased the person into the restaurant and opened fire on those inside. It is as yet unclear whether the shooter's intended target was among those wounded in the incident.

Family members and friends of the teens mourned their deaths in separate vigils outside the closed restaurant Wednesday, ABC Chicago reports.

Ross, according to the Chicago Tribune, was a sophomore at Robeson High School, loved to play basketball and was "a little comedian," known for frequently making jokes.

"We thought that he (had) gone to get some dinner," Ross' aunt Latonya Ross told the Tribune. "Next thing we know, we're getting a call that he's been shot. He just got caught up in the wrong place at the wrong time."

Brown attended the Prosser Career Academy and was remembered by his family as "an achiever" who was looking forward to attending college.

"You took my dreams away. My baby ain't going to have no baby," Brown's mom Regina Brown told ABC.

While Chicago's overall murder rate has dropped in 2011, that is not the case in the city's Englewood neighborhood, where 56 people were killed this year -- a 40 percent increase over 2010, according to a Chicago Sun-Times analysis.
