“Examination of the brain showed advanced Alzheimer’s disease as well as blood vessel changes resulting from chronic high blood pressure.

“Laboratory testing at the scientific laboratories division was negative for Covid-19, influenza, and other common respiratory viruses. Testing for Hantavirus was also negative. Testing for carbon monoxide showed no presence.

“Additionally, there were no autopsy findings indicating a Hantavirus infection in Mr. Hackman.”

Dr. Jarrell went on to address the timeline of their deaths: “I have been asked when death occurred. For these individuals, there is no reliable scientific method to determine the exact time or date of death with complete accuracy.

“Mr. Hackman’s initial pacemaker data recorded cardiac activity on February 17, with subsequent interrogation showing an abnormal atrial fibrillation rhythm on February 18, which was the last recorded heart activity. Based on this information, it is reasonable to conclude that Mr. Hackman likely passed away around February 18.

“Considering the circumstances, it is also reasonable to conclude that Ms. Hackman passed away first, with February 11 being the last time she was known to be alive.”

Dr. Jarrell also provided insight into Hantavirus infection, describing it as a condition that initially presents flu-like symptoms, such as fever, muscle aches, cough, and sometimes vomiting and diarrhea. In severe cases, it can lead to shortness of breath, heart failure, and lung failure.

Santa Fe County Sheriff Adan Mendoza stated that the case will remain “open” until all remaining details have been resolved.
