PORT HURON, Mich. (AP) -- Authorities are awaiting toxicology results before deciding on a cause of a death for a 3-month-old boy who apparently became ill at the St. Clair County courthouse.
The Times Herald of Port Huron reports that an autopsy has determined that physical trauma wasn't a factor in Tuesday morning's death of Casey Churchwell Viola Jr.
Authorities also say there was no physical evidence of poisoning. It's expected to be several weeks before toxicology results are returned.
Rescue crews were called to the courthouse after the baby was found foaming at the mouth with blue lips. He was with his 21-year-old mother, who was going through courthouse security. Police say the boy's condition was discovered when the mother opened a warming cover on an infant carrier holding the child.
