My 76-year-old mother begged me not to leave her alone with my 28-year-old son. Every night, he locked the door of his room, and every morning she seemed more terrified. But when I installed a hidden camera and saw what I was carrying to his room at 3 a.m., I IMMEDIATELY CALLED THE POLICE…

Sometimes they worked.

Other times they made her cry.

“The black bag contains everything the doctor asked us to take to their next appointment,” he said.

I was looking back at my father’s photograph.

“Robert was a very handsome man,” he whispered.

I felt something crumbling inside me.

I’m your daughter, Mom.

She smiled politely.

“Oh, that’s nice.

I turned around so I wouldn’t see myself crying.

But there was still a question that tormented me.

Why were you locking the door of his room?

Daniel looked down, embarrassed.

“I was afraid he would leave the house overnight and get lost. The first time it happened, I found her two blocks away from here. I thought keeping the door locked would protect her.
