Nobody Home!

When Keith returned to his home that day from his work at 5 p.m., he was taken aback to see the terrifying sight of a deserted house. He instantly realized that something bad had happened.

His fears seemed to come true when his attempts at trying to get in contact with his wife ended in vain and he came to know that his children were still in the daycare. This was it for him, as, he did not waste even a second before calling the police. So, now it was up to the police to find out what had exactly happened?
