Qld home combed over double murder probe

A house in Queensland's north has been declared a crime scene in an ongoing investigation into a suspected double murder.

Detectives investigating the disappearance on Chantal Barnett and Robert Martinez searched the house in the Rockhampton suburb of Norman Gardens on Wednesday night, the ABC reports.

The pair disappeared in 2013, but human remains found at a Rockhampton property were confirmed as those of Mr Martinez late last year.
