A man was killed, a 13-year-old boy was critically wounded and three other people were hurt after someone opened fire on a West Englewood front yard Monday night.

The five were outside in the 6700 block of South Winchester at about 8:50 p.m. when multiple people came up on foot and fired as many as 40 shots, according to neighbors.

A man in his 20s was shot in the head and pronounced dead on the scene, police said. His exact age was not immediately available.

Four other people were also wounded. A 13-year-old boy was shot multiple times in the right thigh and went to Comer Children’s Hospital. A 23-year-old man was shot in the left leg and a 30-year-old man was shot in the buttocks and leg; both went to Stroger Hospital. A 34-year-old man was taken to Advocate Christ Medical Center with gunshot wounds to the leg, shoulder and right hand.

Chicago Fire Department Cmdr. Walter Schroeder said all four were taken to hospitals in serious-to-critical condition. Police said their conditions had been stabilized and noted that the 13-year-old was in “critical/stable” condition.

Neighbors must work together to find who is responsible, said community activist Andrew Holmes, who addressed reporters at the scene.

“We as a community are going to be working the blocks to try to find out who and if anybody knows any information,” Holmes said. “It’s up to the community to stand together from the east of Englewood to the west side of Englewood to put a stop to the shooting here. It can be done with the residents speaking up.”

“No matter how old he was, he’s still human and he’s still somebody’s child,” said Holmes of the man who died.

Lisa, who asked to be identified by only her first name, said she had just put her daughters to bed when she heard dozens of gunshots.

She rushed back to their beds to make sure no bullets came through the window.

“It’s just constant violence over here,” she said.

She was outside barbecuing recently when someone started shooting; she had to let her food burn because the gunfire wouldn’t stop. Last year, four men were shot on the same block while her daughter had a birthday party.

They shoot in daylight, they shoot at night, they even shoot when there are officers posted nearby.

“The police, they be on the blocks and they shooting,” she said. “We’ve got idiots with guns.”

These days, Lisa and her family rarely leave the house.

“We can’t use these bike lanes,” she said, gesturing to the lines painted on Marquette Road. “They ought to take this stuff out of here. It’s useless.”

She owns two properties in the city, and recently was told she would owe $12,000 in property taxes. “You want me to spend $12,000 and we can’t go in the yard?”

She nodded around the corner at the crime scene tape stretched across the block.

“This is costing me,” she said. “I pay taxes. I pay for these schools to be built. I pay for these bodies to be dragged off the block.”

Her tenants balk at paying for a place where they feel unsafe, she said.

“They look at me like ‘I’m not finna pay my rent. I can’t even sit on the front porch,’” she said. “I just got a tenant. They say [they’re] scared to go to the mailbox. Three steps out the door! This is embarrassing. As an entrepreneur, this is embarrassing.”

She recently saw someone get shot, go to the hospital, and then come back to the same block.

“You got out of the hospital and you’re walking around again on some bulls–t?” she said. “They don’t need to die. They want to die. If this is the path you choose, you want to die.”

She wants to leave the city with her family, but her properties couldn’t sell for more than a fraction of their assessed value, she said.

“The price of everything goes up, and the value goes down.”

One man was killed and at least four others were wounded in other shootings since Monday afternoon.

A 24-year-old man was fatally shot in Englewood at 10:40 p.m., police said. He was in the 7300 block of South May Street fighting with someone over a gun. The person he was fighting with got hold of the gun and opened fire, shooting the 24-year-old man multiple times. He was taken to Stroger Hospital in critical condition and later pronounced dead.

Earlier Monday, three suspects were taken into custody after two men were shot on the Near South Side, police said.

One man suffered wound to the neck and face and the other was shot in the buttocks at about 1:10 p.m. Monday in the 2600 block of South Federal Street, police said.

Both were taken to Northwestern Memorial Hospital. The man shot in the neck was in critical condition. The other man’s condition was not immediately available.

Police arrested three people, one of them a female, and were searching for a fourth. A gun was recovered.

Metra’s Rock Island line was were shut down from 31st to 35th streets as police investigated and hunted for a weapon, said Metra spokeswoman Meg Reile. The tracks were reopened by 2:20 p.m., Reile said.

Nearby John B. Drake Elementary, 2710 S. Dearborn St., was briefly on lockdown but all students and staff are safe, said Chicago Public Schools spokesman Michael Passman.

Other shootings:

At 11:30 p.m., a 21-year-old man was seriously wounded in an Englewood shooting. He was driving in the 5600 block of South Loomis Street when someone exited a nearby black sedan and fired shots, hitting him twice in the back. He went to Stroger Hospital in serious condition.

At 6:55 p.m., a 38-year-old man was shot during an attempted robbery in South Austin. He was in the 700 block of North Lavergne Avenue when someone walked up, pulled out a handgun, demanded money, then fired shots. The man was shot in the buttocks and went to Mount Sinai Hospital in serious condition.

In addition, a 34-year-old man walked in to MacNeal Hospital in suburban Berwyn on Monday evening, hours after he was shot in Chicago, police said. He had a graze wound to the back and told investigators he was shot at 1:45 a.m. Monday while driving in the 1600 block of North Cicero Avenue. He honked his horn at a vehicle that had stopped at the intersection, then someone in the vehicle fired shots, grazing him in the back, he said.
