Family of 3 and housekeeper found dead in a mansion

A married couple, their young son and a housekeeper were 'bound and threatened' before being murdered in an arson attack by suspects who 'had knowledge of the family', according to police.

Savvas Savopoulos, 46, Amy Savopoulos, 47, and Philip, ten, were found dead along with housekeeper Veralicia Figueroa, 57, after the couple's $2million Northwest Washington DC home was set on fire on Thursday.

Investigators found no signs of forced entry and believe the suspects were able to gain access to the home on Wednesday and stayed overnight as they knew how the family 'lived their day-to-day lives'.

So So sad, nowhere is safe except in the lord presence.
