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

Police have spent a total of 12 weeks searching the SR-85 Landfill and they searched a total of 21,500 tons, or 43,001,653 pounds, of debris.

There were a total of 278 volunteer searchers from various agencies around the Valley.

On average, police had approximately 32 people assisting on a daily basis for the hand search between Oct. 23, 2017 and Dec. 20, 2017

In addition to the searchers, civilian staff and volunteers assisted with the day-to-day operations of the site.  From December 20th, 2017-January 18th, 2018, we had six people assisting daily during the cadaver dog search.  The total man-hours spent at the landfill were 23,650.

In addition to the assistance we received from various Valley agencies for the actual search, the Phoenix Police Department would also like to thank the following community members and businesses for their support and donations of food, drinks, snacks and supplies:

The Phoenix Police Department would like to give special recognition to Diane Strand, a North Valley businesswoman who not only coordinated all of the donations but personally delivered most of the meals to the SR-85 Landfill. Strand was often accompanied by Maritza Galaviz and members of the Mustafa Family. 

This show of support from the community was instrumental in keeping the searchers focused on the task before them, and was greatly appreciated by all.  Finally, the Phoenix Police Department would like to thank John Gilbert, the Foreman of the SR-85 Landfill, for the support received from him and his staff during our operation.
