Air Force major says he feared his powerlifting wife

When millionaire businesswoman and mother Andreen McDonald, 29, vanished from her San Antonio, Texas, home in the winter of 2019, hundreds of people came out to search for her.

On March 1, 2019, the day his wife was reported missing, Andreen's husband, Air Force Major Andre McDonald, told investigators that he had last seen her the night before. He admitted that they had had an argument about their successful assisted living business and that he had left the house to cool off for a few hours at a nearby gas station. When he came home, he said he believed his wife was sleeping in their daughter's bedroom.

"48 Hours" correspondent Peter Van Sant investigates what happened that night in "Andreen McDonald: A Millionaire Vanishes," airing Saturday, Dec. 9 at 10/9c on CBS and streaming on Paramount+.

For months, hundreds searched all over for Andreen McDonald to no avail. Until one day in July 2019 — 133 days after her disappearance — when Andreen's remains were found in a field just six miles away from her home.
