Gray was last seen early in the morning of April 10, 2003 in Spokane, Washington. He sent emails between midnight and 1:00 a.m. and used his cellular phone at 8:00 p.m. that day, but has never been heard from again after that. Gray was reported missing at noon on the day of his disappearance.

On April 11, the day after Gray was last seen, his car was found parked in a loading zone at Clarwood Apartments on the 800 block of Madison Street near where it intersects Interstate 5 in Seattle, Washington. A photograph of his location is posted below this case summary. The car was out of gasoline and was ticketed at this time. It was towed away on April 21. His parents were notified of the car's recovery the following day. There was no sign of Gray in or near the vehicle and few clues as to his whereabouts.

Gray may have been seen in a downtown Seattle homeless shelter on the 28th of April. The man the shelter employees saw was wearing tan slacks and a light-colored stocking cap, which is what Gray was wearing when he was last seen. This sighting has not been confirmed, however. Another shelter saw a man matching Gray's description and took some pictures of him, but when Gray's family viewed the pictures they said it was not him. A man's body found in a marina in Everett, Washington in May 2003 was originally thought to be Gray's but dental records ruled out the possibility.

Gray's case remains unsolved. The circumstances surrounding his disappearance are unclear.
