The Dolton Police Department completed its investigation into the fatal shooting of professional basketball player Khapri Alston, 31, last month, but are waiting for the Cook County state’s attorney’s office to review the case.

Alston was shot and killed May 21 on the 14100 block of Martin Luther King Drive in Dolton.

The Police Department’s investigative findings were sent to the state’s attorney’s office for review, the village said in a statement.

“We understand the community’s concern and the family’s desire for answers,” the statement said. “We share those concerns and recognize the importance of ensuring this matter is handled with the utmost professionalism, integrity, and transparency.”

The decision of whether to file charges will be made by the state’s attorney’s office, the village said.

The state’s attorney’s office confirmed last week it was contacted in the case, but would not comment on a pending investigation.

“As in every case, prosecutors must evaluate all of the available evidence and consider the applicable laws to determine whether we can meet the legal standard for bringing criminal charges,” the office said in a statement.

The case has drawn substantial attention, with controversial former Dolton Mayor Tiffany Henyard among the most prominent voices calling for answers.

“He was beloved and he deserved justice,” Khapri’s father, Chenier Alston, said following the shooting. “We’re not going to stop until we get justice.”

Alston played for several basketball teams both in the United States and abroad, his father said, and won a championship in Chile.

The Club Deportivo Valdivia, whom Alston played for in Chile, posted on its social media last week that it would be holding a Khapri Alston Cup in his honor on June 28 and 29 together with Club Deportes Las Ánimas.
