Police have spent hours searching the home of a man charged in a notorious New York 1979 missing-child case, but it's not yet clear whether investigators found anything relevant.

A lawyer representing the wife of suspect Pedro Hernandez says authorities finished combing the couple's Maple Shade, N.J., home around 3 a.m. Thursday. The search started late Wednesday afternoon.

Police collected items including a computer hard drive and some papers. The lawyer, Robert Gottlieb, says Hernandez' relatives don't know what police were seeking.

New York police have said only that the search related to the continuing investigation into the disappearance of 6-year-old Etan Patz.

Police say Hernandez confessed last month to killing the boy.

Hernandez' lawyer and his wife's lawyer say Hernandez is mentally ill and has had hallucinations.
