Curry paid homage to one of the three victims of the shooting in North Carolina earlier this week by writing Deah Shaddy Barakat's name on his sneakers.
He wore the shoes again during the Shooting Stars competition earlier Saturday night.
Barakat was one of three Muslim college students killed Tuesday in Curry's home state.
"It only seemed right to honor him and his family, and hopefully they know that people are thinking about them," Curry said. "They're not alone, and hopefully it can give them some kind of peace and comfort knowing that he was a special guy. And I just did my little part to shed light toward him."
Curry said there were several connections to the family that touched him.
He said Barakat did his wedding photo similar to a magazine cover featuring Curry and his wife, Ayesha. Barakat also wore a No. 30 jersey -- Curry's number -- in basketball leagues and some of Curry's family members even played pickup games with Barakat in North Carolina.
"They all spoke highly of him," Curry said. "It's a great platform to be on, but it only seemed right."
Barakat's wife, Yusor Mohammad Abu-Salha, and her sister, Razan Mohammad Abu-Salha, also were killed in the attack. Craig Stephen Hicks, 46, has been charged with three counts of first-degree murder in their deaths.
Curry, the starting point guard for the Western Conference in Sunday's All-Star Game at Madison Square Garden, made sure he'd have the chance to shine a bright light on Barakat and his family.
He scored 27 points in the final round. Curry connected on 13 consecutive shots until missing his final attempt, bringing fans and celebrities roaring to their feet after every swish at Brooklyn's Barclays Center.
Thompson, who had an opening-round best of 24, scored only 14 points in the final round. Cleveland's Kyrie Irving finished second with 17 points in the three-man final.
It was a rare year when the 3-point competition had as much -- if not more -- intrigue heading into it than the dunk contest because of the notable names who were -- and weren't -- participating in each.
Curry, who set the NBA record with 272 3-pointers in a season two years ago, finally took home the 3-point crown on his fourth try. He earned bragging rights over his fellow "Splash Brothers" star in the process, putting pressure on Thompson to follow his spotlight-stealing final round.
Atlanta's Kyle Korver, who is shooting a league-high 52.3 percent from beyond the arc, and defending champion Marco Belinelli of San Antonio never made it past the first round with scores of 18. Portland's Wesley Matthews finished with 22, Los Angeles Clippers guard J.J. Redick scored 17 and Houston's James Harden had 15.
