CAVE CREEK, Ariz. – The family of Christine Mustafa, 30, plans to expand the search radius to the Lake Pleasant area Sunday.

Mustafa has been missing since May 15.

"We just need to pray for her to come home at all,” said Craig Hutton, Mustafa's brother-in-law, adding he has accepted the possibility she may no longer be alive.

But with her boyfriend, Robert Interval, 37, behind bars for one count of first-degree murder, the family feels a small dose of closure.

"It's a relief to know that we're finally looking at some answers,” said Hutton, and it has inspired the family to search locations the suspect has frequented.

Friends and family have been searching near Mustafa's Cave Creek home with no luck.

Hutton said Mustafa is a happy person and a loving parent who leaves behind two children without a mother—at least for now.
