The remains of an army veteran and her dog who went missing three months ago are believed to have been found in a shallow grave.

The body of Julia Jacobson and her dog Boogie were thought to have been discovered during a search of the Riverside County desert by 120 officers near Cactus City, about 20 miles east of Indio. Investigators are now using dental records to confirm the identity of the remains.

San Bernardino Sheriff's Department said it received information that led to the search but would not say where it came from.

Dalen Ware, the ex-husband of a 37-year-old who went missing on September 2, was arrested at his home in Phoenix, Arizona, and charged with her murder in October.

Police determined Jacobson had been murdered based on forensic analysis of her car, according to KFMB.

It is believed that Boogie was killed along with his owner.

Jacobson was last seen with her wheaten terrier in Ontario, California, over Labor Day weekend, and then reported missing on September 2.

They also have not released a possible motive for Ware.

Family said they have suspected Ware was involved since she disappeared.

The couple have been divorced for about a year, and according to court documents, Ware had a history of domestic violence.

Jacobson was an Army veteran who worked for a 7-Eleven corporate after serving two tours of duty in Iraq before going missing.

A friend told KFMB that Jacobson texted them on September 2 around 9.30pm to say she was near Palm Springs and planned to travel to Big Bear lake.

Her car was later found abandoned with the keys inside not far from her home in San Diego, more than 100 miles south from where she told her friend she would be.

Ware is being held at Adelanto Detention Center in San Bernardino County in lieu of $1million bail. He will appear in court next month.

After her disappearance, Jacobson's friends made a 'Help Find Julia' Facebook page to share photos and videos of she and Boogie together.

On the page friends wrote that the loss is 'beyond words'.

'Even though Julia's physical presence may be gone and taken from us too soon, her capacity for love, inspirational spirit and laughter will live forever in the hearts and minds of all those that knew and loved her,' a statement on the page said.
