Summary based on the NamUs case record (MP16332) and 1 other source
In the late summer of 2009, a young man named Juan Alcala Avalos vanished under circumstances that remain shrouded in uncertainty. At the age of 19, Juan was last seen on September 9, 2009, in the area of Pima County, Arizona. Originally from Altar, Sonora, Mexico, he was known to be in the process of crossing the border into the United States through Arizona at the time of his disappearance. Juan, also known by the nickname 'Niguas,' was a Hispanic male, standing at approximately 5 feet 4 inches tall and weighing around 125 pounds. He had black hair, which was described as being shaved on the sides and about three centimeters long on top, and brown eyes. When he was last seen, he was wearing a white t-shirt, a sweatshirt of an unknown color, blue jeans, and tennis shoes. He was reportedly wearing two pairs of pants, with a hole cut in one pair to hold his Mexican voter ID card. He was also carrying a scapular and a wallet.

The specific details of what happened to Juan after he began his journey across the border are not publicly known. His family and law enforcement have been left with a painful lack of information regarding his whereabouts or what might have transpired. The journey from Altar, Sonora, through the Arizona desert is notoriously perilous, with dangers ranging from the harsh natural environment to the risk of encountering individuals involved in illicit activities. The report of his disappearance was not filed with the Phoenix Police Department until October 27, 2018, nearly nine years after he was last seen, which can sometimes complicate the initial stages of an investigation.

Despite the passage of time, Juan Avalos's case remains open. Information about his disappearance has been disseminated through various platforms in the hope of generating new leads. The Phoenix Police Department is the investigating agency, and his case is registered in the National Missing and Unidentified Persons System under case number MP16332. The circumstances of his disappearance highlight the vulnerabilities faced by individuals crossing the border and the enduring anguish experienced by families who are left without answers. The overview of this case is one of a young man who embarked on a journey with hopes for the future, only to disappear, leaving a void of information and a family waiting for any news of his fate.
