Police Continue To Look For Answers In Montgomery Co. Boy's Disappearance

MONTGOMERY COUNTY, Md. (WJZ) -- Police are following several leads as they try to find 11-year-old William McQuain. A nationwide Amber Alert remains in effect.

Mike Hellgren has new details of the latest search for William McQuain.

Police won't say what led them to a trail or another location along I-270. So far, nothing has been found as the suspect faces a critical court hearing.

Curtis Lopez will head back to Maryland to face charges that he murdered his estranged wife, Jane McQuain. But what police really want to know is if he can lead them to her son, William. William McQuain has been missing since Sept. 30.

Her friend, Sis Ford, says she spoke to Lopez after the murder, a conversation that now gives her chills.

"He come up and said, `Hello, how are you?' Then he got to talking about how he was going back to New Jersey," Ford said. "He did not mention her, did not mention William."

Investigators searched two parks for William with detectives, horses and cadaver dogs but found nothing.

"The hope is that he is still alive, however we are using teams and people experienced when the person is deceased," said Capt. Paul Starks, Montgomery County Police.

Lopez was arrested in North Carolina where they say he fled after the murder. They say he refused to answer questions about William. According to new court records, police found another woman driving McQuain's SUV and her credit card and a box cutter in the hotel where they arrested Lopez. They found 18 copies of their marriage certificate.

He had a violent past and she told friends she was scared he'd hurt her.

"Why a common person---and I mean COMMON---could do something like that, I'll never know," Ford said.

Police hope William is still alive but admits with each day, that hope is dimming.

Lopez has not been charged with McQuain's disappearance.
