THE family of a Pittsworth mother, who died in her sleep, believe the long-term effects of an assault may have contributed to her death.
Friends and family of Pittsworth woman Angela Casey yesterday farewelled the 35-year-old in a funeral at the town's Anglican church.
She was remembered as a woman who was devoted to her children, one of whom she had lost to leukemia.
Her younger sister Donna Casey said she would never forget the phone call she received on January 31 notifying her of Angela's death.
"My sister was a such a beautiful person, always there to help anyone," Donna said.

Angela had her first child, Tamara, when she was 19.
"She was a single mother but she always went without to give Tamara everything she could have ever wanted."
In 2003, Angela had a little boy Jacob.
Jacob was diagnosed with leukaemia in early 2005.
"For the next five-and-a-half years their lives were spent in and out of the Royal Children's Hospital in Brisbane."
Jacob's treatment included a bone marrow transplant in 2009.
"He had a lot of complications and on the 6th of May, 2010, Jacob lost his battle and passed away in his mother's arms.
"Every day for her was a constant battle but as tough as things were, she somehow managed to get by and still be the best mother to Tamara."
Donna said autopsy results showed Angela had suffered a sudden unexplained death caused by epilepsy due to a seizure she suffered in her sleep.
Those seizures, according to Donna, began after Angela was punched during a night out about 16 months ago.
She said her sister was knocked unconscious when punched in the back of the head after a fight had broken out at the end of the night.
"At this stage Ange was unconscious having an uncontrollable convulsion caused by the massive head trauma from the king hit," Donna said.
Angela was hospitalised but chose not to make a complaint to police.
"Since that night Ange suffered multiple seizures which only occurred since the king hit she received on that terrifying night.
"I still can't believe my beautiful sister is gone.
"I just want to wake up from this nightmare and see my sister's beautiful smiling face."
Pittsworth police officer-in-charge Sergeant Rob Patterson said there was an ongoing coronial investigation into the matter.
