Summary based on the NamUs case record (MP4253) and 8 other sources
Andrew Fernando Mayorga, a 17-year-old from San Antonio, Texas, was last seen on January 4, 2007. He had been staying with a family friend, referred to as an "honorary grandfather," while visiting San Antonio during the holidays. At the time of his disappearance, Andrew had been living in Washington state with his mother and planned to move to Louisiana to live with his grandmother. However, he vanished before his grandmother could arrive to pick him up.

Andrew was last seen at the corner of Soledad and Travis Streets around 7:30 a.m., and he left behind all his personal belongings, including his identification, Social Security card, clothes, and even his pet Chihuahua. Suspicion arose when it was discovered that the family friend disposed of a computer Andrew used before the hard drive could be examined for clues. Despite these odd circumstances, authorities have not named the man a suspect, and the case remains classified as an "endangered runaway."

There have been theories that Andrew may have met someone, either in person or online through social media platforms like MySpace, and left voluntarily. It is believed he could still be in the San Antonio area or may have traveled to other states such as Washington, California, Florida, or Georgia. Despite the passage of time, his family continues to hope for answers and his safe return. His case remains unsolved.
