$1M bond set for a Phoenix man whose girlfriend is missing

A $1 million bond has been set for a Phoenix man arrested on suspicion of first-degree murder in connection with his missing girlfriend.

Robert John Interval didn't have a lawyer at his initial court appearance.

Maricopa County prosecutors sought a high bond amount, saying the 37-year-old Interval is a flight risk.

Phoenix police say detectives developed probable cause to arrest Interval in the case Thursday although the body of 34-year-old Christine Mustafa has yet to be located.

She was last seen on the afternoon of May 10 and failed to show up for her scheduled work shift the next morning.

Mustafa's family asked police to check on her welfare and they went to the home she shares with Interval.

Police say Interval told officers Mustafa left for work on foot.

Another search for Christine is slated for this Sunday at 4:30 a.m. They will be meeting at Cave Creek and Pinnacle Peak roads [see picture above for more specific information].
