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…

He looked at me with fear-filled eyes.

Margaret?

Yes, Mom. It’s me.

For a moment she seemed confused.

Then he whispered something that broke my heart.

Where is your father? I was here just now.

My father had died six years ago.

I turned to Daniel.

“What did you do to him?”

His face contracted with anguish.

“Mom, please, listen to me.

Don’t you think of telling me to calm down!

At that moment the police arrived.

Two officers entered the bedroom. Daniel immediately left.

I pointed it out.

“She locks her up here every night! My mother is terrified of her fault!

One of the officers spoke softly to her.

“Ma’am, do you feel safe? Has anyone hurt you?

My mother stared at him.

Then he looked at Daniel.
