The house where convicted killer Chris Watts strangled his pregnant wife before killing his two infant daughters has been sold for $600,000.
The new owners are a family who hope to "fill it with smiles" to make up for the house's grim history.
In 2018 Watts, who is serving five life sentences behind bars, strangled his wife Shanann, who was 15 weeks pregnant, at the home in Frederick, Colorado.
