Summary based on the NamUs case record (MP50862) and 3 other sources
Valentin Alvarez-Marinez, a 31-year-old Hispanic male, vanished from Carbondale, Pennsylvania, on or around November 1, 2001. At the time of his disappearance, he was described as being between 5 feet 8 inches and 5 feet 10 inches tall, weighing approximately 220 to 225 pounds. He had black hair and brown eyes. When he was last seen, he was reportedly wearing a blue t-shirt, white socks, and black Nike sneakers. The circumstances surrounding his disappearance remain unknown, leaving a painful void for those who knew him.

The initial report of his disappearance was not filed until several years later, on January 20, 2005, when the Carbondale Police Department officially opened an investigation into his whereabouts. This significant gap in time between when he was last seen and when he was formally reported missing has added layers of complexity to the investigation. Details regarding his life, his relationships, and his state of mind at the time he went missing are scarce in public records. This lack of information has made it difficult for law enforcement and the public to piece together a clear timeline of events leading up to his disappearance.

The case of Valentin Alvarez-Marinez is a somber reminder of the many individuals who disappear under unknown circumstances. With very few details available to the public, the investigation has faced considerable challenges over the decades. His case is documented in the National Missing and Unidentified Persons System under case number MP50862. Despite the passage of time, the search for answers continues, fueled by the hope that new information might one day surface and shed light on what happened to Valentin. The overview of his case is one of quiet uncertainty, a man who seemingly vanished, leaving behind only a brief physical description and the enduring question of his fate.
