Curtis Lopez is the suspect in Jane McQuain's Death and William McQuain's disappearance.
ROCKVILLE, Md. (AP) - A man charged with killing his estranged wife and her 11-year-old son is due in court in Montgomery County.
Curtis Lopez's attorneys are asking a judge Thursday to bar from trial evidence about his cell phone records. The case is set for trial this fall.
Lopez was arrested in North Carolina last October and charged in the deaths of his estranged wife, Jane McQuain, whose body was found beaten to death in her Germantown apartment. Her son William was found dead several days later in the woods, and prosecutors say the child was beaten to death with a baseball bat.
Authorities used Lopez's cell phone records to track him to a motel in Charlotte, N.C., where he was arrested.
