Stephen Capaldi was taken into custody on Thursday night and is cooperating with investigators, sources say. So far he has not been charged with a crime.
Bucks County woman missing for weeks; investigators ask public's for help
Detectives were investigating two scenes on Friday afternoon.
One is at Capaldi's home in Sellersville, Pa. near the intersection of High and East Church streets.
Crime scene tape and a mobile command unit could be seen in front of the home.
Behind the home, a white car was being loaded onto a flatbed truck.
The revelations are heartbreaking for so many including Alisia Real.
"I just felt for her and just wanted to do something," said Real.
Real helped organize a group who searched for Capaldi because she felt it was the right thing to do.
"We ran coordinated grid searches to try and find her. We printed out all the flyers and put them everywhere," said Real.
Meanwhile, investigators were also searching near Philadelphia International Airport where, sources say, part of a body was discovered.
It's not yet known if the remains are those of Elizabeth Capaldi.
The district attorney's office has not commented on these developments.
During a news conference in late October, D.A. Matt Weintrub said Capaldi's husband was the last person known to have seen her. He added that Capaldi's car, car keys and cell phone were left at home.
However, her wallet was missing.
Capaldi's adult daughter reported her missing after losing touch with her.
