Unified Police Lt. Justin Hoyal said the 2-year-old boy was at his grandparents' house Tuesday night when a tube-style 32-inch television fell on top of him.
The couple was babysitting the child and were in another room. Hoyal said they heard a loud noise and found the boy pinned underneath the television.
The boy was taken to Intermountain Medical Center at about 5:30 p.m. He was then flown in extremely critical condition to Primary Children's Hospital.
The boy died later Tuesday night.
