Summary based on the NamUs case record (MP15497) and 4 other sources
John William Troyer, a 36-year-old white male, was last seen on December 16, 1999, in San Bernardino, California. He was born on October 16, 1963, making him 36 years old at the time of his disappearance. Troyer is described as having blonde hair and blue eyes, standing at 5 feet 11 inches tall, and weighing approximately 165 pounds.

Troyer has a distinguishing physical characteristic - a scar on his eyebrow. This feature could potentially aid in his identification. The authorities have dental X-rays available for Troyer, which could be crucial for identification purposes if remains are found.

The circumstances surrounding Troyer's disappearance remain unclear, as the available information does not provide details about the events leading up to or following his disappearance. The case has been entered into the National Missing and Unidentified Persons System (NamUs) under case number MP15497. However, it's worth noting that no NCMEC (National Center for Missing & Exploited Children) case number is associated with this disappearance, which might indicate that Troyer was not considered a minor at the time he went missing.

Despite the passage of time since Troyer's disappearance, his case remains unsolved. The lack of additional information suggests that there might be limited leads or public awareness about his case. As with many missing person cases, any new information or leads from the public could be crucial in helping to resolve the mystery of John William Troyer's disappearance.
