Summary based on 1 source
In the autumn of 2022, a journey to the heart of New York City marked the beginning of a period of uncertainty and concern for the family and friends of David Jason Birnbaum. On October 1, 2022, the 30-year-old man embarked on a trip that has since left his loved ones searching for answers. David, a male with a reddish-brown beard and very short, balding brown hair, was last seen in the bustling metropolis of Manhattan. His journey began in Waterloo, Ontario, Canada, where he took an Uber for a cross-border trip into the United States. This ride would take him across the border at Fort Erie/Buffalo and continue all the way to one of the world's most iconic landmarks.

The Uber ride concluded in front of the Empire State Building, where David was dropped off. At the time of his disappearance, he was wearing brown pants, a blue t-shirt, a coat, and running shoes. He was 5'10" and weighed approximately 120 pounds. David was also known to be carrying his cell phone and a laptop. Those who know him have noted that he has mental health issues, a detail that adds to the concern for his well-being. The last confirmed sighting of David was at this location in New York City, and since then, his whereabouts have remained unknown.

The investigation into David's disappearance is being handled by the Waterloo Regional Police Services in Ontario, Canada, as his journey originated from their jurisdiction. His case is documented under the case number WA-22-269369. Information provided by his family has been crucial in piecing together his last known movements. This overview of the case highlights the journey of a man who traveled a significant distance only to vanish in one of the busiest cities in the world, leaving a void of information and a family waiting for any news of his whereabouts.
