(CBS/AP) CLARKSBURG, Md. -- Maryland police confirmed Wednesday that the body of a young boy found on Tuesday is that of 11-year-old William McQuain, who had been missing for over two weeks.
The remains were found in a rural area of Montgomery County, Md., by a dog handler. Police Chief J. Thomas Manger said the boy's body is believed to have been at the rural location where it was found Tuesday since Oct. 1.
Authorities began searching for William, who was last seen Sept. 30, after his mother, Jane McQuain, was found dead Wednesday night in the bedroom of her home in Germantown, about 30 miles northwest of Washington. Investigators said she was stabbed to death.
Shortly after McQuain's body was found, her estranged husband, Curtis Lopez, was arrested in Charlotte.
A police search warrant revealed that authorities think Lopez, who has ties to the area, showed up in Charlotte in McQuain's SUV on Oct. 1 or 2. The warrant also says police seized several pieces of evidence from Lopez's hotel room, including McQuain's credit card, a box cutter, a book bag and a wallet.
Jane McQuain's ex-boyfriend, Ronald McCombs, told The Associated Press last week that she had told him several weeks ago that she feared for her safety and was concerned Lopez might harm her. He said the two had recently been arguing.
Police say they have not ruled out the death penalty in the case.
On Monday, Lopez waived his extradition and is due back in Montgomery County.
