Johannesburg - Two men accused of killing two siblings in Northcliff appeared in the Johannesburg Magistrate's Court on Thursday, Gauteng police said.

Their bail application was not finalised and would continue on Friday, said Lt-Col Lungelo Dlamini.

Gary Smith and his sister Karen Buchanan were bound with rags and their mouths duct-taped shut before they were assaulted on March 14, 2008.

Their teeth were pulled out, darts were thrown at them and Buchanan was stripped naked. Later, they were both shot in the head.

Buchanan was killed by a shot to the back of the head. Her brother was shot in the mouth.

Their bodies were found by a domestic worker. - Sapa
