CHICAGO (CBS) — The Christmas holiday ended in tragedy at one South Side home.

Seven people were shot while gathering outside a home in the East Chatham neighborhood. Two of those victims, who are said to be brothers, have died.

CB2’s Mike Puccinelli is at Stroger Hospital with more on the condition of the victims transported there. Some victims are being treated at two other hospitals as well Monday morning.

The shooting occurred Sunday night around 9:20 p.m., as a group of people were gathered on the front porch of a home in the 8600 block of South Maryland. Police said an unknown individual wearing a gray hoodie emerged from an alley and opened fire on the people gathered on the porch. The shooter then fled the scene.

The shooter then ran away from the scene, which is about 100 yards from a bank on 87th Street and about a block from a strip mall anchored by a Walgreens and a Target store, according to police.

Multiple ambulances had to be called out to transport the victims to area hospitals.

James Gill, 18, was shot in the head and pronounced dead at the scene, according to police and the Cook County medical examiner’s office. Roy Gill III, 21, was shot multiple times and taken to Christ Medical Center in Oak Lawn, where he was pronounced dead, authorities said. The older man was a convicted felon, according to police.

A 35-year-old man suffered multiple gunshot wounds and was also taken to Christ, where he was listed in critical condition, police said. He is also a convicted felon.

A fourth male, whose age was not known, was shot in the body and taken in critical condition to Stroger Hospital, police said. Also, a 27-year-old man and 21-year-old woman both suffered a gunshot wound to the leg and were taken to Stroger, where their conditions were stabilized. The 27-year-old man was also a documented gang member, police said.

A 39-year-old man shot in the foot later showed up at Roseland Community Hospital, where he was listed in good condition, police said. He is a documented gang member and convicted felon, according to police.

Multiple rounds were fired and evidence markers dotted the ground where some of the casings fell.

Activist Andrew Holmes was at the scene and spoke with CBS 2 about what he said may provide a break in the case.

“Hopefully the cameras that are on the buildings here, they should be working,” Holmes said. “This is a business area. Hopefully the cameras pointing east of here and the cameras in the alley can the Chicago Police Department some images of the perpetrator.”

It is not clear, where or if, the crime was caught on video.

The shooter is still on the loose Monday morning. So far there have been no arrests.

One female is among the seven victims. Ages range from at least 21 to 39. Police have not released the age of two of the deceased victims.
