A man in Hillsborough County killed his five-year-old son and then himself, a tragedy discovered by the mother in their Lutz home, leaving the community in shock.

Sheriff’s officials said they were called just before 10 a.m. Friday to a report that two people were dead inside a home.

The mother called the sheriff's office saying she was trying to pick up her son from the father's house on Cranbrook Drive, but nobody was answering the door. At around 7:30 a.m., deputies went to the house and didn't see any suspicious activity or signs of foul play.
