Tragic couple found dead in Sydney's west

Police say nobody else was involved after a couple who killed their severely disabled son was found dead at their Sydney home yesterday.

The bodies of Margaret and Raymond Sutton were discovered at their property at Leonay, near Penrith yesterday morning.

Police are investigating whether the couple, aged in their late 60s, took their own lives.

Mr and Mrs Sutton killed 28-year-old Matthew in April 2001.

In 2005 they admitted to the killing and in 2007 they were placed on five-year good behaviour bonds, with a judge saying no further sentence could add to their suffering.

Police say it's unclear how the couple died.
