Escalante also mentioned a 20-year-old man who was killed in a double shooting in Austin shortly before 8 p.m.



Carlos Harding and another 20-year-old man were found shot inside a black SUV in the 100 block of North Lavergne Avenue. Harding suffered a gunshot wound to the head and was taken to Stroger Hospital, where he was pronounced dead, police said. The other man was shot in the leg and was stabilized at Stroger, Quaid said.



Escalante noted that Harding had a record of 61 arrests. "Sixty-one arrests at the age of 20," he said. "That's the frustration we deal with. He has, and I believe it is correct but we'll double check, he has 20 convictions. Now granted, most of them are low-level misdemeanors but he has 20 convictions at the age of 20 years old.



"So no matter what plans and strategies we put in place -- and I do believe we put good plans and strategies in place each week and each weekend -- until we get everyone else, whether it's the courts, our state legislators, other community activists, to step up with us and hold people accountable for their gun violence, we're going to continue to see it, unfortunately," he said. "And unfortunately, it may impact the same communities no matter what we try to do."



Harding was killed a little more than a mile north of the double shooting at the house party, which occurred shortly before midnight Sunday. An 18-year-old was shot in the head and another man, 33, was shot in the chest and the right leg, and was stabilized at Stroger Hospital, police said.



The 18-year-old was pronounced dead on the scene. Officers and detectives huddled around his body in a grassy area in front of a two-story home on the northern side of Jackson. Officers cordoned off about half a block of Jackson between Lavergne and Leamington avenues.



Donre Domio said she was inside a home on the block when her teenage son yelled, "They're shooting. They're shooting."



She said the block, where her mother had lived for at least four decades, has been generally quiet.



About three hours after the shooting, a man in a white T-shirt and jeans walked away from the crime scene. He said the 18-year-old was his brother.



The man put his hands on the back of his head and leaned on the building of Christ the King Jesuit College Preparatory School at Jackson and Leamington. A woman in gray sweater and pants hugged him.



Police said no one was in custody.



The most violent stretch of the weekend was late Saturday through early Sunday when at least 22 people were shot, three of them fatally, including 15-year-old Travon D. Smith.



Travon was shot in the Kenwood neighborhood around 12:50 a.m. Sunday as he walked with a 16-year-old boy in the 4700 block of South Ellis Avenue, police said. A red van pulled up, and someone inside fired shots. Travon dropped to the ground and was pronounced dead at the scene, police said.



Three more people were killed and 15 others were wounded Sunday morning through the night, according to police. A man was killed and 18 others were wounded between 5 p.m. Friday and 5 a.m. Saturday.



Saturday evening, a 40-year-old man was shot by police in the West Garfield Park neighborhood during a raid on a business suspected of storing illegal weapons, authorities said.
