Authorities said the death of a 50-year-old man in a Fairfax County jail has been classified as accidental after a medical examiner’s report showed he fell during a medical emergency and hit his head on the floor.

The case of Monty Roy Saito of Santa Clara, Calif., dates to November 2015 when he was extradited to Fairfax on several drug-related charges.

Saito arrived at the Fairfax jail Nov. 10 and faced six felony drug charges related to offenses in 2014, according to police and court records. He was put in a minimum-security wing with his own cell, officials said.

But six days later, a deputy heard a noise and found Saito lying on the floor outside his cell. The deputy thought Saito was having a seizure, and he was taken to an area hospital where he was treated and later released. He was then placed in the jail infirmary.

Saito was later found on the floor of his cell in the infirmary, unresponsive but breathing, officials said. He was taken back to an area hospital, where he was put on life support. He died a few days later.

Police in Fairfax County said an autopsy report from the Office of the Medical Examiner found that Saito’s cause of death was “blunt head trauma, resulting from striking his head on the floor when he collapsed during the initial medical emergency.”

Detectives were working to finish the investigation into Saito’s death and turn over the case to local prosecutors for a review, according to a police statement. At the time of his death in 2015, several inmates had died at the Fairfax jail.

In February 2015, Natasha McKenna died after struggling with deputies and receiving four jolts from a Taser. A medical examiner attributed her death to “excited delirium” and ruled her death an accident.

Then in October 2015, a 68-year-old man collapsed and died in the county’s jail. It was later ruled that the man, Paul Guida, died from natural causes. He had heart disease and diabetes.
