“The cause of death is deferred,” said Coroner’s spokesman Craig Harvey. “That means that the doctors have not entered a cause of death in the system pending receipt of lab test results and tissue studies they have ordered.”

Harvey said it could be 4 to 8 weeks before a cause of death is finally determined.

Winchester’s body has not been released from the Coroner’s Office. The 23-month old boy died after spending several hours in the family car after a shopping trip, when his mother assumed other children were looking after him. The temperature outside the vehicle was 95 degrees.
