KABC reported that authorities are confused as to how Veronica Aguilar apparently kept her special-needs son Yonatan Aguilar a secret from the rest of the family for three years.

The boy's stepdad, Jose Pinzon, testified that the mother of four told him Yonatan was sent to Mexico to get better.

Yonatan was found dead wrapped in a blanket in a closet in August 2016.

"I saw a very gaunt, frail-looking child, who at that time to me looked like a 5-, 6- or 7-year-old boy," said LAPD Det. Abel Munoz, the news outlet reported.

A doctor testified the boy was so malnourished that his knee bones were the biggest part of his legs.
