Nine people were killed and at least 30 others were wounded in shootings across Chicago between Friday night and Monday morning.

The weekend’s latest fatal shooting happened about 12:10 a.m. Monday in the Chicago Lawn neighborhood on the Southwest Side. Javier Pantoja, 26, was standing next to a car in the 3000 block of West 60th Street when a tan vehicle drove by westbound and someone inside fired shots, according to Chicago Police and the Cook County medical examiner’s office. Pantoja, whose home address was not known, suffered multiple gunshot wounds and was pronounced dead at the scene at 12:25 a.m.

Three people were killed in a Sunday evening shooting in the East Side neighborhood on the Far South Side. Narcisco Ledesman, 22 of North Austin; 17-year-old Antonio J. Lopez of East Chicago, Ind.; and a 24-year-old woman all suffered multiple gunshot wounds to the body at 5:30 p.m. in the 10200 block of South Ewing and pronounced dead at the scene, according to police and the medical examiner’s office. The woman’s name has not been released.

A police source said a man shot the three people after they broke into his home. No charges have been filed against the homeowner, who had a valid Firearm Owner’s Identification card.

Police entered the residence and found the homeowner locked in a basement bedroom and the bodies of the three people on the ground, NBC5 News reported. Police were investigating the shooting as self-defense.

It was unclear whether the intruders were armed, NBC5 reported. No other injuries were reported in the shooting.

Ivan Real, who told NBC5 he is a close friend of the homeowner, said there have been a lot of home invasions in the neighborhood recently.

“There have been a lot of home invasions in this area, so that didn’t come to me as a surprise, but I’m flabbergasted because it happened to one of my close friends,” Real told NBC5 News. “I’m really just concerned for my friend and glad he’s OK.”

About 11:20 a.m. Sunday, Emmanuel Fleming, 34, and 46-year-old Michael Swift were killed in a shooting in the West Side Austin neighborhood. The men were standing at 11:19 a.m. in the 200 block of South Laramie when two people walked up and fired shots at the younger man, authorities said. Both men suffered gunshot wounds to their bodies. The shooters then drove away southbound in a silver or gray SUV.

Fleming was taken to Stroger Hospital, while Swift was taken to Mount Sinai Hospital, authorities said. They were both pronounced dead less than an hour later. Fleming lived in the Englewood neighborhood on the South Side, and Swift lived in the West Garfield Park neighborhood. Deputy Chief Al Nagode said one of the victims was believed to be a member of a nearby church.

A man, thought to be 25 years old, was shot to death at 6:52 a.m. Sunday in the Uptown neighborhood on the North Side. He was in the 1000 block of West Montrose when a black vehicle approached and someone wearing a black hooded sweatshirt got out and opened fire, striking him twice in the torso. He was taken to Illinois Masonic Medical Center, where he died at 7:35 a.m., police and the medical examiner’s office said. His identity has not been released.

Shortly before 12:30 a.m. Sunday, 27-year-old Demica Porter was gunned down in the Back of the Yards neighborhood on the South Side. Officers responded to a call of shots fired and found her lying on the sidewalk in the 1400 block of West 54th Street. Porter, who lived in the same neighborhood, had been shot in the neck and legs and was taken to Stroger Hospital, where she died at 1:13 a.m., authorities said.

Less than an hour earlier, Jabari H. Feazell, 20, was fatally shot in the Old Town neighborhood. He was involved in a fight with two other males at 12:07 a.m. in the 1300 block of North Hudson when one of the suspects pulled out a handgun and opened fire, authorities said. He was shot in the head and was taken to Northwestern Memorial Hospital, where he was pronounced dead. He lived in Austin.

Additionally, an off-duty Chicago Police sergeant shot a man at 5:06 a.m. Sunday in the Morgan Park neighborhood on the Far South Side. The officer shot the 18-year-old during an “armed confrontation” in the 10900 block of South Hermosa. The man was taken to Christ Medical Center in Oak Lawn, where his condition was stabilized.

Chicago Police Supt. Eddie Johnson said the officer first spotted the man “acting suspiciously” in the 10000 block of South Wood. The incident then “escalated in some way,” prompting the officer to shoot the man.

Last weekend, three people were killed and 27 others were wounded in shootings across Chicago.
