Angela Christine Mack, known as Angie, was a 20-year-old mother when she and her four-year-old son, Thomas Mikey Rettew, vanished from the Alton, Missouri area in the fall of 2002. Angela, described as a white female with blonde hair and blue eyes, about 5 feet 3 inches and 100 pounds, had left Salem, Arkansas earlier that year in a late-model dark gray or blue Chevrolet or GMC extended cab pickup with Missouri plates.

According to accounts, Angela left Mikey in the care of Clarence and Barbara Krusen in Alton; reports conflict over whether the Krusens were formally adopting him or had been given him. Angela later traveled to Chowchilla, California and in December 2002 phoned her mother saying she planned to return to Missouri to regain custody. It is believed someone picked her up at a Springfield bus station and took her to the Krusens’ home, after which neither she nor Mikey were seen again. The disappearances were not reported until August 2004.

Investigators later learned of the Krusens’ informal adoption. Clarence Krusen died in 2012. In October 2020 Barbara Krusen, after failing a polygraph, said Clarence had murdered Angela and Mikey and burned their bodies in a farmhouse furnace. No remains have been recovered.
