The investigation continues into what caused the death of a nine-month old infant earlier this year.

The Natrona County Sheriff's Office says it has received a postmortem toxicology examination report, but not a full autopsy report in regards to the infant that died in February, on the 2700 block of Robertson Road.

For now, a Department spokes-person says investigators do not have a definitive answer on the cause of death.

The autopsy is being done in Adams County, Colorado.
