A two-year-old boy was pronounced dead upon arrival at the hospital after he was found unconscious inside a hot van in Miami Wednesday, police said.
Detectives said several people including the driver of the van were being questioned.
Miami Fire Captain Ignatius Carroll said the call came in as a child in cardiac arrest around 3:45 p.m.
The incident happpened at Vision for Life Academy located at Northwest 41st Street and 7th Avenue. The van has signage that reads "Reaching Children For Christ Ministry."
Police said the boy, identified as Angel Gabriel Matute-Chavez, was found in the rear compartment of the van. Officials did not say how long he was left in the van. It's unclear if the child was properly restrained.
"When you see someone so young and helpless, and fragile that isn't able to tell you what's happening, what's going on, then that's when you start fearing the worst and a whole lot of things go through your mind," said Capt. Ignatius Carroll, Miami Fire Rescue.
According to investigators, the driver dropped off other children then sometime later another driver spotted the toddler in the van.
Emergency crews rushed the toddler boy to Jackson Memorial Hospital's Ryder Trauma Center where police said he died upon arrival.
The child's identity has not been released.
NBC 6 checked out the facility's record from July which shows the academy is in good standing. However, records show the center doesn't provide transportation.
The day care center has not responded to a request for comment.
