SCHENECTADY, N.Y. -- Schenectady Police investigators have stepped up their presence at the home of a mother as they look for her 4-month-old baby boy.

Wednesday, police searched the area around the State Street home of Heaven Puleski. A day earlier, Schenectady Police were asking for the public's help finding the mother and child.

Puleski's aunt tells Spectrum News she spoke to her niece on Monday after not hearing from her since sometime in June.

Police say Puleski is cooperating, but not providing much information.
