"Calls from Inside the House"

In 1987, a babysitter in the U.S. called police because she kept receiving

strange phone calls. The voice asked only one thing: “Have you checked the children?”

At first, police told her it was probably a prank. But the calls kept

coming—closer together, more urgent. Finally, an officer traced the call.

He rushed back on the line and shouted: “Get out of the house. The call is coming

from inside.” The babysitter fled. Upstairs, police found the children murdered.

The killer was never officially identified.
