Two girls, 13 and 14, were shot on the South Side as a violent Christmas weekend came to a close during one of the most violent years in Chicago in decades.



A total of 61 people were shot in the city during the holiday weekend and 11 of them died of their wounds, according to data kept by the Tribune. Seven people were killed on Christmas Day alone, more than on the holiday the past three years combined. Three people were killed in 2015, one in 2014, and two in 2013.



The number of people shot over the holiday weekend also sharply outpaced recent years. During the Christmas weekend in 2015, 29 people were shot and seven of them died. In 2014, when Christmas fell on a Thursday, the four-day weekend included 35 people shot and seven people killed, according to Tribune data.



This past weekend's toll pushed the total number of people shot in Chicago this year to more than 4,300 and the number of homicides to around 770. Last year, there were 2,989 shooting victims and 492 homicides.



Most of the shootings occurred on the West and South sides, in neighborhoods that have borne the brunt of the gun violence this year. They ranged from Austin and West Humboldt Park on the West Side to Gresham and Chatham on the South Side.



There were eight shootings involving multiple victims and two double homicides. One of them was an attack during a party in the East Chatham neighborhood that left two brothers dead and five others wounded.



Chicago police Superintendent Eddie Johnson said most of the weekend's victims were targeted by gang members.



"The violence primarily occurred in areas with historical gang conflicts on the South and West sides of the city," Johnson said the day after Christmas. "We now know that the majority of these shootings and homicides were targeted attacks by gangs against potential rival gang members and groups who were at holiday gatherings.



"These were deliberate and planned shootings by one gang against another," he added. "They were targeted knowing fully well that individuals would be at the homes of family and friends celebrating the holidays. This was followed by several acts of retaliation."



Police spokesman Anthony Guglielmi said 90 percent of those killed during the weekend "had gang affiliations, criminal histories and were pre-identified by the department's strategic subject algorithm as being a potential suspect or victim of gun violence."



Among the last people shot during the long weekend were two young teenage girls wounded in Gresham while waiting in a van for their father, according to police.



The girls were with a 2-year-old boy outside Leland Giants Park just after 11:30 p.m. Monday, police said. The 13-year-old's father had just left the van to speak with someone in a house when two people came up and fired into the vehicle, police said.



The 14-year-old was hit in the back and was taken to Comer Children's Hospital in critical condition. The 13-year-old was grazed in the arm and was taken to St. Bernard Hospital in good condition. The 2-year-old was unharmed, police said.



Guglielmi said the father was a gang member and police "are operating under the belief that the father was the intended target."
