Kira Trevino, 30, was last seen the night of Feb. 21 as she left work at the Mall of America, but authorities found so much blood in her car and home in St. Paul that they believe she is dead. Her 39-year-old husband was charged on Feb. 28 with two counts of second-degree murder in her death.

On Friday, Jeffery Trevino's attorney, John Conard, argued in court that he lacks documents and test results that are being withheld, making it hard to evaluate his client's case, the station reports.

But the judge ruled that there's sufficient probable cause to continue towards trial.

Many of Kira's relatives were present at the hearing Friday. Outside the courtroom, Jeffery Trevino's family declined comment.

The search for Kira's body proceeds as many volunteers, friends and relatives continue to center their efforts around Keller Lake in Maplewood, Minn. The lake, which is less than two miles from the Trevino home, became a point of interest in the investigation after several tips pointed authorities to the location.

Search efforts at the lake produced a bag containing a bloody pillow and pillowcase, a bra, shirt and a sponge. The DNA on those items matched that of Kira Trevino, according to CBS Minnesota.

On Thursday, a candlelight vigil was held for Kira at the lake. Her family said they hope to find the body so they can give her a proper burial.

"We're not going to stop until Kira is found, and we can bring her home," Kira's father, Jeff Steger, said.
