Summary based on the NamUs case record (MP19184) and 3 other sources
On a winter day in Phoenix, Arizona, on January 28, 1994, a 44-year-old man named Ramon Herrera Vasquez seemingly vanished. He was last seen in the area of West Thomas Road and North 81st Drive in Maricopa County. His disappearance was unsettlingly abrupt, as he left behind all of his personal belongings. Without any explanation or communication, Ramon has not been seen or heard from by his loved ones since that day, leaving a void filled with unanswered questions and lingering uncertainty.

Ramon Vasquez is a Hispanic male with black hair and brown eyes. At the time he went missing, he stood between five feet five and five feet seven inches tall and weighed approximately 155 to 165 pounds. He sometimes wore glasses and typically had a mustache. Those who knew him might recall a few distinct physical characteristics: he had moles on the left side of his neck and a split fingernail on one of his thumbs. These small details paint a picture of the man whose absence has been felt for decades.

The circumstances surrounding Ramon's disappearance remain a mystery. After he was last seen, a report was filed with the Phoenix Police Department on January 31, 1994, officially beginning the search. Despite the passage of time, the case remains open, a cold but not forgotten file. In an effort to bring about a resolution, DNA samples were provided by his brother and daughter and have been entered into national databases, a modern tool offering a glimmer of hope for answers. The overview of this case is one of sudden and complete disappearance; a man in his mid-forties vanished from his community, leaving everything he owned behind, creating a painful and enduring mystery for his family and investigators.
