Summary based on the NamUs case record (MP124737) and 3 other sources
In the late summer of 2005, a family's connection to David Joseph Giago went silent. The 43-year-old male was last heard from on August 9, 2005, when he made a phone call to his family from a payphone in Tempe, Arizona. During this call, he informed them that he had left his adult group home. An enrolled member of the Oglala Sioux Tribe, David was a man of American Indian/Alaska Native and White/Caucasian descent. At the time he went missing, he was described as being 5 feet 8 inches tall and weighing approximately 145 pounds, with brown hair and brown eyes. A distinctive smiley-face tattoo, about two inches in size, was on his upper arm.

The circumstances surrounding David's departure from the group home and his subsequent actions remain largely unknown. The brief phone call to his family was the last contact anyone has had with him. Since that day, his whereabouts have become a painful mystery for his loved ones. The lack of communication and the absence of any leads have left a void filled with unanswered questions and concern for his well-being. The Phoenix Police Department is the primary agency investigating his disappearance, and they have been seeking any information that could shed light on what happened to David after that final phone call.

Years have passed since David Giago vanished, and his case remains an open and unresolved missing person investigation. The passage of time has not diminished the hope of his family and community for answers. His physical description, including his receding hairline and the unique tattoo on his arm, have been circulated in the hopes that someone might recognize him or recall seeing him. The investigation into his disappearance is a reminder of the many Indigenous people who go missing each year, and the enduring pain their families experience. The search for David continues, a testament to the unwavering hope of finding him and bringing him home.
