Chicago police were questioning two people on Saturday in connection with the shooting death of a cousin of Chicago Bull Dwyane Wade as they looked into the possibility that the stray bullet that killed her was fired during a robbery attempt involving a driver for the ride-sharing app Uber, authorities said.

Nykea Aldridge, 32, and a man were walking in the 6300 block of South Calumet Avenue about 3:30 p.m. Friday, authorities and the family spokesman said. Police said on Friday that two men approached Aldridge and the man and began firing at the man, and it was unclear whether he was hit by gunfire.

Aldridge, who was pushing her baby in a stroller, was hit in the head and the arm and taken to Stroger Hospital, where she died, police said. The baby was not hurt, and a relative came to the scene and took the child, police said.

Police said Aldridge, a mother of four young children, including the baby who is just weeks old, was an unintended target.

But authorities now are looking into the possibility that the young mother was struck as she passed an unfolding robbery involving an Uber driver — possibly a target of a holdup — and another man, according to a Chicago police spokesman. Reached later Saturday, Uber had no public comment about the case.

Detectives were questioning the Uber driver as well as a second person in connection with the fatal shooting.

"They're solely people of interest," police spokesman Anthony Guglielmi said.

Wade has only commented publicly about the tragedy through his Twitter account, posting on Saturday: "RIP Nykea Aldridge... #EnoughIsEnough" as well as "The city of Chicago is hurting. We need more help & more hands on deck."

Aldridge's slaying is not the first time a relative of Wade's, who signed with the Bulls as a free agent in the offseason, has been a victim of violence.

In late March 2012, Wade's nephew Darin Johnson was shot twice in the leg when two gunmen opened fire in a South Side convenience store. One man was killed and five, including Johnson, were injured.

Newly minted Chicago Bull and Robbins, Ill., native Dwyane Wade participated in an ESPN town hall on athletes, social responsibility and gun violence held at a South Side YMCA on Aug. 25, 2016, a day before his 32-year-old cousin was shot and killed in the Parkway Gardens neighborhood, also on Chicago's South Side.

But this latest blow to Wade's family came just a day after Wade was interviewed about growing up in Chicago's violent streets as part of an ESPN program taped at the South Side YMCA called "An Undefeated Conversation: Athletes, Responsibility, and Violence." The program also included Wade's mother, Jolinda, a local pastor who spoke to reporters Friday after her niece's death. Jolinda Wade, whose sister is Aldridge's mother, is a pastor at New Creation Binding and Loosing Ministries at 129th and Halsted streets, where a 1 p.m. Sunday prayer service is planned in honor of the slain woman.

Wade spoke about being insulated from the influence of gang violence and drugs by his family. "My experience, when I was (in Chicago), it was a lot of us killing us," Wade told host Jemele Hill, adding that he has tried to assist youth with his Wade's World Foundation.

Six years ago, while playing for the Miami Heat, Wade met with and gave gifts to the family of Kevin Jones, a South Side high school basketball player who idolized Wade, after the 15-year-old was killed by a stray bullet at a graduation party.
