Autopsies completed on the Criado family Thursday showed the mother and two of her children had been stabbed in the neck and carbon monoxide poisoning was a contributing cause in all of their deaths.
Jackson County Deputy State Medical Examiner Dr. James Olson reported that the mother, 30-year-old Tabasha Paige-Criado, died as a result of multiple stab wounds to the neck and abdomen.
Two boys, Isaac, 6, and Andrew, 5, suffered stab wounds to the neck. The other two children, Elijah, 7, and Aurora, 2, died of carbon monoxide poisoning from inhaling smoke during an arson fire set at their home at 1027 W. 10th St. on Monday morning. (Correction: See below.)
The final determination of the cause of death is pending toxicology results, which can take several weeks to complete, police said in a release.
Olson could not be reached by phone Thursday night for further comment.
Medford police remain tight-lipped on the circumstances surrounding the killings, declining to comment on where the victims were in the house while the fire burned within.
Medford police Lt. Bob Hansen said work continues on the case, as suspect Jordan Criado, the husband of Paige-Criado and the children's father, remains unresponsive and on a mechanical ventilator at Rogue Valley Medical Center.
"We are working to put together the pieces of what we have of the puzzle," Hansen said. "We are busy on the case and hope that we can get a complete picture of what happened if the suspect regains consciousness. But we don't know when, or if, that will occur at this point."
Hansen did not speculate on what turn the case would take if Criado remains unresponsive for an extended period of time.
Also on Thursday, Medford police declined to release the audio recording and transcripts from the 9-1-1 calls made Monday morning and the missing person's report taken by officers just hours before the murders.
Paige-Criado was reported missing at 5:30 a.m. and was returned to the house when contacted by police at 7:45 a.m. Police have said she showed no fear in going home.
Hansen cited the continuing investigation in the department's decision not to release the information.
"These recordings can contain important information in our investigation," Hansen said. "The information will be made available to the defense if the case goes that far."
Hansen said the recordings can contain background noise or conversations between victim and suspect that could shed light on what led up to the killings.
"We also do not want to affect the jury pool if this comes to trial," Hansen said.
