A South Side shooting left four girls and a boy hurt, and on the Northwest Side a 15-year-old girl was shot while riding in a vehicle as shootings across the city Sunday night added to the toll of a violent holiday weekend.

The weekend toll for gun violence in the city includes at least nine people dead and at least 36 wounded. Two of the deaths came Sunday morning when a Cook County Sheriff's Office correctional officer apparently shot to death his wife, a Chicago police officer, inside their Southwest Side home before turning the gun on himself, authorities said. Three of the deaths and 14 of the wounded were shot between 9 a.m. and 10 p.m. Sunday.

Five of the children shot Sunday night, who range in age from 11 to 15, were shot by someone who fired from a car shortly after 7:30 p.m. on the 6600 block of South Michigan Avenue in the Park Manor neighborhood on the South Side, police said.

The children had been playing at a park next to a nearby elementary school and were walking home when a car pulled up and someone asked if they were in a particular gang, family members and police said.

It was not immediately clear whether the group had time to respond. One relative said they had said they were not in the gang; another said shots rang out before they could answer. In any case, someone inside the car opened fire, hitting four girls and a boy.

Authorities said the youngest of the injured, an 11-year-old girl, was the most seriously wounded and was taken to John H. Stroger, Jr. Hospital of Cook County in critical condition.

The girl, a 5th grader who just hours earlier had returned from church and shared an Easter dinner with relatives, was struck by two bullets, one that hit her chin and one that punctured a lung and broke her collarbone, her parents said.

Despite her injuries, Tymisha Washington was talking with her parents from her bed in the intensive care unit this morning.

"She says she's ready to go home," said her father, 29-year-old Cory Lesser, standing outside Stroger's emergency room about 3 a.m. with Washington's mother. "She's tired of the doctors poking her with needles."

Also at Stroger was a 15-year-old girl shot in the arm. Police said her condition was stabilized.

Two 14-year-olds, a girl and a boy, were taken to Comer Children's Hospital after the shooting. The girl, who was shot in the abdomen, was in serious condition, police said. The boy was shot in leg, and police said his condition was stabilized.

A fifth victim, a 14-year-old girl grazed in the buttocks, was taken to St. Bernard Hospital and Health Care Center after the shooting. Because the girl was not taken by ambulance, officials did not initially include her in the number of people shot.

Early Sunday afternoon, two people died from their injuries in a shooting about 1 p.m. on the 2800 block of South Sawyer Avenue in the West Side's Little Village neighborhood.

A 33-year-old man was shot in the head and pronounced dead at the scene. The Cook County medical examiner's office said it was notified of a death at that location.

Another man, 19, suffered a wound to his chest and was taken to an area hospital in serious condition, said Chicago Police Department News Affairs Officer Jose Estrada. He later died from his injuries, Officer Veejay Zala said.

According to a police source, the two men who were killed were traveling in a vehicle with two other adults and two children, ages three and seven. The men were shot on Sawyer Avenue, but after the shooting someone drove them to the 2400 block of South Kedzie Avenue, the source said.

According to the source, police believe the victims were shot by an occupant of an orange or yellow Hummer that fled the scene after the shooting. There was a later report that a car matching the Hummer's description was on fire in an alley on the 3200 block of West 37th Place, about a mile south of where the shootings occurred, but that has not been confirmed by the office of News Affairs.

The Hummer is believed to belong to one of the shooting victims' relatives and it is not clear if there was a confrontation before the shooting. It's also not clear if the Hummer was reported stolen prior to the shooting, according to the source.

Estrada said the circumstances leading up to the fatal shooting were not immediately available.

Earlier Sunday, there were two other shootings in Little Village, each with gang overtones. A 25-year-old man was shot in the abdomen about 1:30 a.m. on Hamlin Avenue between 24th and 25th Streets and a 35-year-old man was shot about an hour later at 27th Street and Kildare Avenue. In both instances, gang slogans were shouted by the attackers.

In other shootings Sunday afternoon:

• About 12:20 a.m. a 23-year-old man was shot in the 9500 block of South Loomis Street in the Longwood Manor neighborhood on the South Side, police said. The man was sitting inside a vehicle when he was shot in the arm, according to police. He was taken in good condition to Advocate Christ Medical Center in Oak Lawn.

• About 9:50 p.m., a 17-year-old boy and an 18-year-old man were shot while walking on the sidewalk in the 8200 block of South Avalon Avenue in the Avalon Park neighborhood on the South Side, police said. Two or three people stepped out of a gangway and at least one of them opened fire, striking the 17-year-old in the calf and the 18-year-old in the arm. The boy was taken to Jackson Park Hospital, and the 18-year-old was taken to Advocate Trinity Hospital, police said. Their conditions were stablized.

• About 9:40 p.m., a 15-year-old passenger was shot inside a vehicle stopped at a traffic light in the 1700 block of North Pulaski Road in the Hermosa neighborhood on the Northwest Side. Three people crossing the street flashed gang signs and at least one of them opened fire at the vehicle, police said. The girl was struck in the back and the driver took her to Saints Mary and Elizabeth Hospital, where her condition was stabilized.

• Also about 9:40 p.m., a 35-year-old man was shot while standing on the sidewalk in the 900 block of West 19th Street in the Pilsen neighborhood on the West Side.

• Two men, ages 25 and 20, were shot about 3:28 p.m. Sunday on the 6800 block of South Laflin Street in the city's Englewood neighborhood on the South Side.

The 20-year-old was shot twice in his face and was self transported to Holy Cross Hospital before being taken by Chicago Fire Department paramedics to Mount Sinai Hospital. His condition was not immediately available, police said.

• Two men, ages 27 and 30, were shot about 9 a.m. on the 8300 block of South Ada Street in the Gresham neighborhood on the South Side, Estrada said.
