CHICAGO — Chicago recorded its 300th homicide this weekend and tallied six others over a 60-hour period that saw 55 people shot, 13 fatally, from Friday afternoon through early Monday morning.

So far this year, close to 1,800 people have been shot across the city and more than 200 of those wounded have died from their wounds, according to records kept by the Chicago Tribune. A total of 306 people have been killed this year, by shooting, stabbing or other means.

A 3-year-old boy was among the wounded who survived the weekend shootings. Police said he’s in critical condition. The 3-year-old was shot in the right shoulder near East 61st Street and South Kimbark Avenue in the Woodlawn neighborhood at 6:15 p.m. Sunday, police said. The boy was in a car seat when an unknown attacker fired shots at the car, police said. People in the vehicle managed to get the boy to University of Chicago Medical Center. He was then transferred to Comer Children’s Hospital in critical condition.

Five people were fatally shot and nine others were hurt between Friday afternoon and Saturday morning. Four of the fatalities occurred in seven hours. The fatalities included a 16-year-old boy who was killed in West Englewood about 9:05 p.m. Friday. He was in the front passenger seat of a car driving through an alley in the 6500 block of South Hamilton Avenue when two males came up and fired shots, according to police.

At least 28 people were wounded, three fatally, in shootings from 8:30 a.m. Saturday to 4:30 a.m. Sunday, the equivalent of somebody shot every 43 minutes. One fatal shooting occurred during a possible murder-suicide in Hyde Park about 9:50 a.m. Saturday, police said. Police responded to the 1400 block of East 54th Street for a well-being check and found a 65-year-old woman with a gunshot wound to the head. A man, 73, also was found shot in the head.

Five more people were killed and seven others, including the 3-year-old boy, were wounded from Sunday afternoon to early Monday. One of the fatalities Sunday was a 21-year-old man shot with “possibly an AK-47” assault rifle in the Back of the Yards neighborhood, according to police. Police initially said the victim was 17. The 21-year-old, who the Cook County medical examiner’s office said was Salvador Suarez, was walking east in the 1700 block of West 46th Street around 1:30 p.m. when a light-colored, four-door Saturn pulled up and fired shots with a “high-powered semi-automatic weapon,” striking the victim as he attempted to run, said Eugene Roy, chief of detectives for the Chicago police.

Suarez lived in the 4500 block of South Hermitage Avenue, according to the medical examiner’s office. Police are investigating whether the rifle has been used in any other shootings. The victim was pronounced dead on the scene, and the shooting was believed to be gang related, Roy said.

A Chicago police officer also shot and wounded a male who allegedly pointed gun at him near Humboldt Park on Sunday evening. The male suspect, whose age was not immediately available, was shot in the lower extremities, and he was listed in serious-but-stable condition at Stroger Hospital.
