An autopsy is being conducted Tuesday on a 15-year-old boy who died while trying out for a high school basketball team in Frankfort.

Franklin County Deputy Coroner Kelly T. Adams says it's still uncertain what caused the death of freshman Waseeq Shahid. Adams says preliminary autopsy results may be available on Tuesday, but final results could take weeks.

Franklin County Public Schools spokeswoman Wayne Dominick says Shahid was about 6 minutes into his first practice at Western Hills High School when he collapsed Monday afternoon. He was pronounced dead a short time later.

Dominick says Shahid had cleared a standard physical examination last week.

The funeral was scheduled for Tuesday afternoon in Elizabethtown.
