A 19-year-old man charged over the double murder of a mother and daughter in their home has appeared in a Perth court.
Lesley Jonathon Cameron appeared in the Stirling Gardens Magistrates Court via video link from prison on Wednesday, charged with the murders of Maureen Anne Horstman, 67, and her 26-year-old daughter Tamara Alexandra Horstman.
The pair were found on December 29 by Tamara's twin brother, Nicholas Horstman, who called police.
Mr Cameron was arrested less than two days later at a house near where he allegedly dumped Tamara's car.
He was not required to plead to the charges and the matter was adjourned until March 26.
