Stephen Capaldi is charged with strangling his wife to death in their bedroom and dismembering her body the following day in their home, the DA told reporters.
He disposed of her remains across greater Philadelphia, including in a Montgomery County dumpster and a riverbank in Delaware County, officials believe.
As Daily Voice has reported, Elizabeth Capaldi was reported missing by her daughter on Oct. 12. Her cell phone, car, and keys were all recovered from the home, but her wallet was apparently taken with her, authorities said at the time.
Stephen Capaldi was taken into custody last week for questioning before a grand jury, but had not been charged with a crime at that time.
He is now incarcerated at the Bucks County lockup without bail, Weintraub said.
The DA said investigators have "some theories" for an apparent motive, and said that a grand jury report found the accused killer was dating another woman around the time of his wife's death.
The investigation remains ongoing, and officials said they have not recovered all of her remains.
The victim's family thanked the community for its interest and support in Elizabeth Capaldi's disappearance, but will no longer be addressing the matter publicly, the DA added.
