A St. Louis, Missouri, man is struggling to understand how his mother kept a baby in her freezer for decades.

Following his mother's death, Adam Smith finally opened a white cardboard box she'd kept in her freezer.

Assuming it was a cake topper, he'd never opened it or asked what it was. He was astonished to find the remains of a frozen, newborn baby, wrapped in a pink fleece baby blanket.

Smith says he dimly remembers his mother once crying, "my first born Jennifer would have been 21 years old today." Smith Smith called police immediately, who arrived in minutes.
