Police have spent hours searching the home of a man charged with murdering a 6-year-old New York City boy who went missing in 1979, but it's not yet clear whether investigators have found anything relevant.

A lawyer for 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.

New York police have said only that the search related to the investigation into the disappearance of Etan Patz (AY'-tahn PAYTS).

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

Police say Hernandez confessed last month to killing the boy. Hernandez's lawyer and his wife's lawyer say Hernandez is mentally ill.
