Ex-husband arrested for murder of Army vet who vanished with her dog

LAVEEN, Ariz. -- Police have arrested the ex-husband of a southern California Army veteran who vanished last month along with her dog, reports CBS affiliate KFMB.

Police said 37-year-old Julia Jacobson last seen in Ontario, Calif. with her wheaten terrier Boogie over Labor Day weekend and was reported missing to the San Diego Police Department on Sept. 2.

Investigators in Ontario determined she was murdered, based in part on a forensic analysis of Jacobson's car, police said.

Jacobson's ex-husband Dalen Ware was taken into custody Friday at his suburban Phoenix home. He's reportedly been charged with murder.

Jacobson's remains haven't been found. Her dog Boogie is also believed dead, according to KFMB.

Family told the station they have long suspected Ware in her disappearance. The couple had reportedly been divorced for about a year. 

KFMB uncovered court records that indicate he had a history of domestic violence.

Friends told the San Diego Union Tribune Jacobson worked for a 7-Eleven corporate office and was an Army veteran who served two tours of duty in Iraq. She reportedly last texted a friend Sept. 2 around 9:30 p.m. saying she was in the Palm Springs area and planned to travel to Big Bear Lake.

Her car was reportedly found abandoned with the keys inside not far from her San Diego home, more than 100 miles south. Police wouldn't say what evidence found in the car led them to believe she had been killed.

They also haven't released a possible motive.

Friends said on the "Help Find Julia Jacobson" Facebook page that her loss is "beyond words."

"Even though Julia's physical presence may be gone and taken from us far 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," the statement said.
