Details of Disappearance
Patrick disappeared from his hometown of Upland, California on January 20, 1988. He told his mother that he was going with a friend to a basketball game at Upland High School. There was a basketball game that evening, but it was being played in nearby Chino, California, not in Upland.
Patrick and his friend went to the Pizza Chalet on Foothill Boulevard and Euclid Avenue in Upland at 9:00 p.m. They had visited the establishment earlier that day as well. He and his friend played video games there and then Patrick left to walk home. A witness saw him leave with an unidentified adolescent male. Patrick's parents waited up all night for him to come home, but he never arrived. They reported him missing early the next morning.
The police initially thought Patrick had run away from home due to a court case. He'd gotten into an altercation with another child at Sierra Vista Elementary School and was required to go to juvenile court about it. However, his parents never believed this would have caused him to run, particularly without his favorite blanket which he always slept with.
Shortly after Patrick's disappearance, the owners of the Pizza Chalet closed the restaurant and left town. There were rumors that they had returned to their country of origin. There is no evidence that they had any knowledge of what happened to Patrick. His case remains unsolved.
