A family of four, including two children with "significant disabilities", were found dead in a home in Sydney's northern beaches, in what police have described as a "tragic" and "horrific" event.
Colombian born Maria Claudia Lutz and her husband Fernando Manrique were found dead in their home in the suburb of Davidson, in an apparent murder-suicide.
Also dead were their two children, 11-year old Elisa and 10-year old Martin.
Both suffered from autism.
Fernando worked for international logistics company Drake, but Maria had given up her career as a lawyer to help care for the two children.
While it's unclear how the family died, it highlights the pressures being faced by families caring for children with autism.
