A 15-year-old boy was shot and killed at a birthday party in north Minneapolis Sunday night, police said.

An investigation is underway into what exactly led up to his death. 

The Minneapolis Police Department said a single shot was fired in a basement near Russell and 29th avenues just before 11 p.m.

Police believe several teenage boys were celebrating a birthday at the time. Police said the initial 911 call was for a self-inflicted gunshot wound, but they later learned the victim may have been shot by someone else. 

Police do have one boy in custody as a person of interest.

The victim was identified as Aundre Loyd, 15, who according to officials was a freshman at Cooper High School. 

Principal Shaunece Smith said in a written statement, "We are a caring community, and we will continue to support one another through this difficult time."

A family member told WCCO that he loved basketball, and had ambitions of playing in the NBA.

While police piece together what happened, Chief Brian O'Hara said he's thinking about the family.

"As a father myself, I cannot imagine what it would be like to go through a crime of violence to your child like this, and we are working to determine exactly the circumstances of what occurred," O'Hara said.

Cooper High School officials say school counselors and social workers will be available at the school on Wednesday to provide support for students and staff.
