Nicholas Plaza was a 5-year-old boy from San Antonio who was last seen at his home on October 23, 2001. His disappearance was not reported until November 21, and investigators came to suspect foul play. His mother, Priscilla Plaza, and her boyfriend, Ruben Zavala Jr. were implicated; they told others that Nicholas had died and that his body was disposed of, but his remains have never been found. Both were later convicted of related crimes and received prison sentences. Nicholas himself has never been located.
