THE Rockhampton Homicide Squad has stepped in on the search for missing Rockhampton pair Robert Martinez and Chantal Barnett.
Although police yesterday said they weren't treating the case as a murder investigation, they were still keeping their options open to the possibility the pair were dead.
Inspector Darrin Shadlow said yesterday that police continued to treat the case as suspicious because it was out of character for the pair not to contact family in such a long time.
The homicide squad has been working with State Emergency Service crews and Rockhampton CIB officers in the search for more than two months.
Searches have been conducted at Gavial Creek, at the end of Quay St, and the Pink Lily Lagoon in the past two months.
The two people have been missing since late February this year.
If you have any information that could help police in their investigations contact Crime Stoppers on 1800 333 000.
