Details of Disappearance

Angela was last seen in Salem, Arkansas on September 1, 2002. She disappeared along with her son, Thomas Rettew, riding a late model dark gray or blue Chevrolet or GMC extended cab pickup truck with Missouri license plates. Neither of them have been heard from again.

Angela was married at the time of her disappearance, but she was in a relationship with another man, Matthew Niederbach. They have one son together, who was left behind when Angela and Thomas disappeared. Both Angela's husband and Niederbach live in Salem. Thomas is Angela's son by a previous relationship; his biological father died in Idaho in 2019.

For unclear reasons, Angela's disappearance was not reported until August 2004, nearly two years after she and Thomas disappeared. There were reports that she was going to California and/or Iowa. Investigators believe the man Angela was involved with have vital information in her case. There are rumors that she was murdered and buried on top of a fresh grave in the Salem area, and that her son was trafficked or was murdered along with her.

Angela and Thomas disappeared from Alton, Missouri, which is forty miles northeast of Salem. They are considered missing under suspicious circumstances.
