The mother suspected of killing her 9-year-old son before committing suicide left a series of haunting Facebook posts in the days leading up to their deaths.

Erica Bond, 47, and her son Lachlan, 9, were found inside their weatherboard home on the New South Wales Central Coast last week.

Neighbours have told of the horrifying moment they heard a grandmother's screams after she discovered the bodies of her daughter-in-law and grandson inside their Central Coast home.

Emergency services were called to the home on Kilpa Rd just before 2pm yesterday following the apparent murder-suicide.

Neighbours in the quiet coast street said they heard the grandmother scream after she reportedly found her 9-year-old grandson Lachlan in his room and the body of his mother Erica Bond, 47.

Those close by rushed to help but despite their calls, the two were unable to be revived.

Bond, who was well-known in the community and a passionate golfer, shared several posts about depression in the lead up to her death.

In one of her last Facebook posts she shared video about suicide prevention.

Another message shared on July 10 read: "Depression is REAL. People can smile all day and still be broken inside."

Other photos posted online show Bond was a loving mum to her young son.

However, loving family photos documenting trips to the zoo and the local golf course painted a very different picture to the messages shared on Facebook.

Bond was a well known golfer in her local community and worked at Kooindah Waters Golf Club as a golf shop and drinks cart assistant.

Police could not comment on the cause of death but did confirm officers were not looking for any other people relating to the incident.

Tuggerah Lakes police command acting inspector Matt Kelly confirmed to the Central Coast Gosford Express Advocate the two deaths were a murder-suicide.

Lachlan was a pupil at Tuggerawong Public School and its principal Grant McFarland wrote a message in response to the deaths on social media.

"By now many of you would have heard that one of our students and parent has passed away," he wrote on the school's Facebook page.

"I wanted to confirm that the school will be open tomorrow (today) and that we are ensuring that significant additional support is available for any student who may need it tomorrow and over the coming days.
