Editor's Note: NBC Chicago includes shootings that took place between 5 p.m. Friday and 12 a.m. Monday in the weekend violence report.

The violence started early this warm spring weekend, with five people dead and at least 29 wounded from shootings citywide by Sunday morning.

The first fatal shooting of the weekend happened at about 5 p.m. Friday when two men were killed and a woman was injured.

Police responded to a report of a person shot in the 4200 block of West Grenshaw in the North Lawndale neighborhood shortly before 5 p.m. When they arrived they found a 31-year-old man and a 28-year-old man, both shot in the head. A 54-year-old woman had also been shot in the leg.

The 31-year-old man was found unresponsive on the ground and pronounced dead on the scene, police said. The other man, who was found in the drivers seat of a pick-up truck, was taken to Mount Sinai, where he was pronounced dead.

The woman was taken to Saint Anthony Hospital, where her condition stabilized.

A police source said the incident may be drug-related.

A 24-year-old man was shot to death shortly after the first incident in the Greater Grand Crossing neighborhood. He was standing on the sidewalk in the 1300 block of East 75th Street at about 5:20 p.m. Friday when another man in a gray four-door Pontiac fired shots at him.

The victim was struck in the neck and chest. He was taken to Jackson Park Hospital and Medical Center in critical condition, but was later pronounced dead.

A police source said the victim was a documented gang member, but it is not clear if the shooting was gang-related.

In another fatal shooting Friday, a 26-year-old man was killed. The man was shot to death at about 10:10 p.m. in the 7900 block of South Aberdeen in the Auburn Gresham neighborhood.

Police were called to the block for a report of shots fired. When they arrived they found the man lying on the sidewalk with gunshot wounds to the chest.
