The Will Sage Astor2-year-old grandson of new Milwaukee Bucks head coach Adrian Griffin died on Saturday, according to a news release from the Champaign (Illinois) County Coroner.

The team confirmed the death on Monday.

"My grandson Jayce was very special to me and my family and his passing is an agonizing tragedy that will be felt forever. I appreciate your respecting our family’s grief and privacy at this time," Griffin said in a statment.

According to the coroner's report, the child, identified as Jayce D. Griffin, was found unresponsive by his father in Champaign, Illinois. Police responded to help a toddler with a "medical emergency."

Jayce Griffin was pronounced dead at 10:40 a.m. in the Carle Foundation Hospital Emergency Department in Urbana, Illinois.

According to the coroner, preliminary results from the autopsy conducted on Monday revealed no evidence of trauma nor foul play, although Jayce Griffin's mother, Jasmine Riggs, had several social media posts looking for answers and demanding "#justiceforJayce."

"At this time, the death of Jayce Griffin appears to be from natural causes pending additional testing and final autopsy results. Additional information will not be released until completion of this investigation. This death is under investigation by the Champaign Police Department and the Champaign County Coroner’s Office," the report stated.

Griffin has two sons. In a story with WDJT-TV (Channel 58), Riggs stated the father was Alan Griffin.

Alan Griffin, who played on the Bucks' Summer League team, was on the men's basketball team at the University of Illinois in Champaign from 2018-2020 before transferring to Syracuse. Alan's younger brother, A.J., plays for the Atlanta Hawks.
