Confusing text sent to family before Perth woman Jessica Bairnsfather-Scott's death

Homicide detectives are investigating after a woman was found dead in her Perth home in the early hours of Sunday morning.

Devastated family members gathered at the Nollamara home of Jessica Bairnsfather-Scott, a 32-year-old healthcare worker, whose body was found inside the May Drive home on Sunday morning.

"There is no known ongoing risk to the public at this stage," a WA Police statement said.

No more information was released about her death, but according to Nine News, the family received a confusing text from her phone earlier that day, containing a photo of a car crash.

"Her husband was saying they were both fine but he wouldn't let us speak to my sister and we knew something was up and kept on trying to call," her sister Alison Gibson said.

"We didn't believe him and came here but we couldn't get in the front door because it was deadbolted.

"Gerard jumped on the roof and got inside and found her."

It's understood a man known to Bairnsfather-Scott is assisting police with their investigation, but no arrests have yet been made.

Bairnsfather-Scott was "the life of the party," her sister said.

"She was always smiling, she always made everyone happy around her," Gibson told Nine News.

"We are a really close family."

Distraught relatives were seen comforting each other outside the home on Sunday.
