Franklin County Sheriff Gary Toelke said Tuesday afternoon that the St. Louis County Medical Examiner's Office had not been able to determine the cause of death of a 2-month-old baby found unresponsive earlier in the day.

There were no obvious signs of what caused the baby's death, the sheriff said. Investigators now are awaiting results of toxicology tests, which could take several weeks, he said.
