It’s been more than a decade and no one has still ever heard from Stuart Issac who left for a cross-country road trip to Yellowstone National Park in 2010.

Stuart Isaac a native of the Republic of Palau was living in Burtonsville, Maryland with his family in 2010. A stocky man at 5’8” and 215 lbs, Stuart Issac was not usually an outdoorsman, but on September 6, Stuart decided to pack a bag, write a note to his family and leave for a road trip to Yellowstone National Park in his 2009, black Lexus Sedan—with no prior experience with hiking or camping. On September 7, 2010, 32 hours after he left his home in Burtonsville, Maryland, Stuart arrived at Yellowstone National Park. Then, 2 weeks later, he phoned an old friend from high school, on September 24th. Since Matsue lives in Guam, typically the two communicate via email or text. The call was unexpected because of the time change—it was 3:30 am EST for Stuart. The call lasted for at least two hours.

Two days later on September 26, Stuart parked his 2009 black Lexus IS-250 sedan with a license plate that read BELLEK at Craig Pass, which is approximately eight miles east of Old Faithful Geyser  Yellowstone National Grand Loop Road in Wyoming.

Stuart was discovered missing during a routine night patrol in the Craig Pass area later that night. An officer had discovered Stuart’s abandoned unlocked car with his keys still inside but no other trace of Stuart. Craig Pass is known to have an approximate elevation of 8,262 feet and has a mountain pass located near Continental Drive. There were no hiking trails in this area. A land and air search began immediately but no sign of Stuart.

A timeline of events for Stuart’s disappearance

• September 6, 2010: Stuart left a note for his family telling them he would be going on a cross-country road trip. The note does not mention when he plans on returning.
• September 7, 2010 | Stuart arrives at Yellowstone National Park. The drive is roughly 32 hours from his home in Burtonsville, Maryland.
• September 24, 2010 | Stuart’s whereabouts are unaccounted for until September 24th when Stuart has a two-hour-long phone call with his friend from high school, Matsue Evens. Typically Matsue and Stuart communicated through text or email, therefore it was odd that he was calling. She lives in Guam, when Stuart called her it was 6:30 PM for her and 3:30 AM EST for him.
• September 26, 2010 | Stuart parks his black 2009 Lexus IS-250 Sedan at Craig Pass. This area has no hiking trail. His vanity license plate read BELLEK”. The car was unlocked and the keys were left inside. About eight miles East of Yellowstone National Park Grand Loop Road.
• September 26, 2010 | Later that day, Stuart's abandoned car is discovered by a routine patrol check. Stuart is nowhere to be found. A land and air search begins immediately for Stuart.

It is still a mystery as to why Stuart went to Yellowstone so abruptly. And to this day he is still missing. Where was he between the time when he arrived at the park and when he called his friend weeks later? Were you in the Yellowstone National Park area on September 24, 2010 and remember seeing a 2009 black Lexus IS-250 Sedan?

While the data is limited, it is estimated that approximately 29 unresolved missing people cases date back to the 1950s. Sadly, the National Park Service does not have a comprehensive database dedicated to unsolved cases.
