Summary based on the NamUs case record (MP1191) and 7 other sources
In the early morning hours of April 13, 2004, Felix Francisco Grullon, a 51-year-old resident of West New York, New Jersey, vanished from his home. Known to his loved ones as Nino, he was last seen at his residence in the area of 60th Street and Hudson Avenue at approximately 5:00 a.m. Later that morning, his mother arrived for a visit and was met with a deeply unsettling scene: the front door to his home was open, and Felix was gone. He has not been seen or heard from since that day. The disappearance was immediate and absolute, leaving behind a void of information and a family grasping for answers.

The circumstances surrounding Grullon's disappearance paint a picture of a man grappling with significant personal challenges. Just weeks before he went missing, he had lost his job with the West New York Department of Public Works. He was also facing financial difficulties, evidenced by the fact that his telephone service had been disconnected because he was unable to pay the bill. On the very day he disappeared, he was scheduled to appear in court for a child support matter and had planned to visit the unemployment office afterward. Compounding these stressors, Grullon was struggling with alcoholism. He had stopped drinking shortly before he vanished and, as a result, was experiencing hallucinations, a severe symptom of withdrawal. Strikingly, he left behind all of his personal belongings, including his keys, wallet, toothbrush, and passport, suggesting he did not intend to leave.

In the years following his disappearance, the investigation has yielded very little evidence to explain what happened to Felix Grullon. A single, puzzling clue emerged later in 2004 when his family received a phone call from an unknown individual claiming Grullon was in a hospital. Police diligently checked medical facilities and rehabilitation centers in the area, but found no trace of him. Born in the Dominican Republic, Grullon was a Hispanic male with graying hair and brown eyes, who used reading glasses. At the time he went missing, he was described as being 5'5' tall and weighing around 150 pounds. The absence of any concrete leads has left his family in a prolonged state of uncertainty, fearing for his safety as the years continue to pass without a resolution. The case remains an unsolved and troubling mystery, a story of a man who walked out of his life one morning, leaving only questions behind.
