According the Chicago Tribune, 61 people were shot and 11 were killed during a deadly Christmas weekend that began on December 23.
Gang violence has been blamed for the bloodshed on the city's south and west sides Christmas weekend.
According to the spokesman for Chicago's Police Department, Anthony Guglielmi, he claims that the majority of the shootings and violence that has taken place in the southern and western regions of the state is due to past conflicts and quarrels amongst rival gangs.
Johnson said police have recovered 45 guns from the streets since Friday.
A dozen fatal shootings this Christmas weekend continued Chicago's spike in violence this year. More than 750 people have been killed in Chicago in 2016, marking the first time in almost two decades that the number slain has exceeded 700, according to the Tribune.
It marks a sharp rise in homicides and shootings since past year in one of the largest American cities, located in the state of IL.
'They were targeted knowing full well that individuals would be at the homes of family and friends celebrating the holiday, ' Johnson said. The 13-year-old's father had reportedly left the van to speak to someone in a nearby house when two people came up and shot inside the vehicle.
Approximately 30 people were shot over Christmas weekend 2015 in Chicago, resulting in six fatalities. "This was followed by several acts of retaliation", he added.

The last weekend of mass destruction was the four-day Thanksgiving weekend, when 61 people were injured and nine killed.
