Child porn extends SA killer's jail term

An Adelaide law student jailed for the manslaughter of his mother has had his jail term increased for possessing child pornography.

Wei Li is serving a nine-year sentence for bashing and strangling Emma Tien at the family's Adelaide home in 2011.

He has now been ordered by the South Australian District Court to serve an extra 10 months and two weeks over the child exploitation material found on his laptop computer during the investigation of his mother's death.
