Olga Edwards, the mother of the two teenage children who were murdered by their estranged father, John Edwards, in their West Pennant Hills home in July of this year, has been found dead by police.

As reported The Daily Telegraph, officers went to her Sydney home at 10am this morning after the solicitor was unable to be contacted.

According to the publication, a police source claimed she had “been struggling lately.”

Currently, the 37-year-old’s cause of death has not been released by NSW Police, however the Daily Mail reports her death is not being “treated as suspicious”.

On July 20, 2018, Olga's two children - 15-year-old Jack and 13-year-old Jennifer Edwards - were shot by her ex-husband who committed a "planned and premeditated" attack against the teenagers. Their 68-year-old father shot them in the bedroom of their Hull Road home at West Pennant Hills at about 5.20pm in the afternoon.

At the time police told The Daily Telegraph that the Edwards' children "were trying to hide in a bedroom and were huddled together when he opened fire".

The financial planner then took his own life 12 hours later at his Normanhurst home.

It was also reported that upon arriving home to the "horrific scene," Olga collapsed from “severe shock.”

AAP reports her overseas family is currently being notified.
