Luis Angel Sanchez was 3 years old when he was last seen in Tracy, California, on June 6, 2001. He lived with his mother, Katherine Kitty Sanchez, and her boyfriend, William Krumlinde, in a room at the Hacienda Inn motel. His disappearance was not reported until July 2002, a delay that prompted investigation.

Authorities concluded Luis was the victim of foul play. Investigators believe he was killed inside the motel room and later buried in a nearby field. Krumlinde was charged with murder; Katherine Sanchez was charged with child endangerment and assisting in disposal of the body. She later admitted to being intoxicated and said she could not recall where Luis was buried. Searches, including one in August 2002 that recovered unrelated bone fragments, did not find Luis’s remains.

Both Katherine Sanchez and William Krumlinde pleaded guilty to roles in the crime and received prison sentences. Luis’s remains have never been recovered. If anyone knew Luis, his movements in June 2001, or anything about the Hacienda Inn room or nearby fields, please share what you know.
