However, the Phoenix Police Department extended the search after the 9-week period came to a close because they wanted to thoroughly search the entire area they thought the body might be.

With the search expected to conclude on Friday, Sgt. Alan Pfohl said a wrap-up will be released early next week.

Her live-in boyfriend, Robert Interval Jr. 37, was arrested in her presumed death. He pleaded not guilty to first-degree murder when he was arraigned in June. 

Although Mustafa’s body has not been found, search warrant paperwork says investigators found evidence of blood in the home she and Interval shared.

Investigators eliminated all other possibilities before concluding that her body is likely at the landfill southwest of Phoenix.

Video previously released by police showed dozens of searchers wearing rubber boots and protective clothing and face masks using long-tined rakes to examine material excavated from the landfill by a power shovel.
