SPRINGFIELD, Mass. (CBS) – Investigators are using ground penetrating radar at the Springfield home where three bodies were found after the arrest of a man who allegedly held a woman captive for a month.

On Sunday, Springfield Police were involved in a chase with 40-year-old Stewart Weldon. When they stopped Weldon, a woman in the car said she had been held captive for a month, raped and beaten.

Wednesday night, investigators went to a home on Route 20 where Weldon’s mother lives and discovered three dead bodies.

Police officers stood guard at the home Thursday into Friday, protecting the crime scene. The search has focused on a garage and nearby yard, which is covered by a tent.

Department of Children and Families spokesman Andrea Grossman confirmed that the agency took custody of a child from the home.

“The Department of Children and Families took emergency custody of a child in the home and is investigating in collaboration with law enforcement,” Grossman, said.

Hampden District Attorney Anthony Gulluni said ground penetrating radar is being used to search for any “areas of interest.”

“Our expectation is we will be here for days, if not longer than that,” said Gulluni.

During a Thursday night press conference, Gulluni said it is a “very complicated investigation” and “all hands are on deck.”

One neighbor said Weldon would wear his hood and tie it up so you could only see his face.

“Strange looking, quiet, kept to himself. Looked like an angry man,” added neighbor LeAnne Lumiere.

Gulluni said there is no reason to believe Weldon had any accomplices.

Still, one neighbor who asked not to be identified said she is terrified by the discoveries.
