PHOENIX (AP) — A Phoenix man who recently reported his wife of 30 years missing has been arrested on suspicion of first-degree murder, police said Wednesday.

They said 57-year-old Joseph Concialdi is being held on a $2 million cash bond after probable cause was developed to make an arrest in the case Tuesday.

It was unclear Wednesday if he has a lawyer who can speak on his behalf.

Police said forensic evidence led them to believe 59-year-old Julie Concialdi was a homicide victim although her body hasn’t been found.

Court documents described evidence of a sanitized crime scene at the couple’s Phoenix home house with blood that matched the woman’s DNA.

Police said Julie Concialdi’s truck was found burned and abandoned on Sept. 4.

Two days later, police said Joseph Concialdi called to report his wife missing.

Police said he told them he last saw his wife on Sept. 4 when they had an argument over a vacation and he left to go camping near Payson.

Julie Concialdi’s family said she uncharacteristically stopped returning calls and messages on Sept. 2 and failed to show up for appointments and work.

All of her belongings plus her cellphone, wallet and medications were still in the couple’s home, police said.
