The cause and manner of a Boise man’s death are pending, after officials say his body tested negative for coronavirus and influenza.

Frederick Gilbert was pronounced dead on Sunday. Gilbert hadn’t been seen for several days and the Boise Police Department had completed a welfare check on him. The coroner’s office was dispatched after the check.

The Idaho Press reports, Gilbert had recently traveled to China and India, and on the evening of Feb. 5th he arrived back in Boise from Los Angeles, having originally left from China. Because of that, the Ada County Coroner’s Office coordinated with Idaho’s Central District Health and the Centers for Disease Control and Prevention to test Gilbert for coronavirus and influenza.

Both tests were returned negative, but more test are being done by the CDC.

The coronavirus outbreak has infected over 45,000 people worldwide, largely in China, and has killed more than 1,100.
