New York ( CNN ) -- CNN has obtained an exclusive photograph of Pedro Hernandez , suspect in the death of 6-year-old Etan Patz , who remains under the care of doctors after being ordered to undergo a psychiatric examination to determine whether he 's competent to stand trial . The photograph was taken five years ago and shows him in a suit and tie , wearing glasses . Investigators are currently digging into a computer drive and two satchels , among other items , removed during the execution of a search warrant at the home of Hernandez , the attorney for Hernandez 's wife said Thursday . The search warrant was executed as part of the ongoing investigation into Etan 's disappearance in 1979 . Hernandez was arrested last month . Police said he confessed to strangling the boy and throwing his body away in a trash bag . The search began Wednesday afternoon and wrapped up at 3 a.m. Thursday at the couple 's New Jersey house , said Robert Gottlieb , who represents Rosemary Hernandez . He said his client `` does n't know what they were looking for . '' The satchels contained personal items including paperwork belonging to Rosemary Hernandez , he said . Gottlieb said his client was home during the search and cooperated fully . `` An assistant prosecutor called me before investigators entered the house and asked whether she was willing to be there to offer assistance , and she did . She was there in five , 10 minutes . '' Rosemary Hernandez feels that her husband 's confession is unreliable and is coming from a mentally ill man , Gottlieb said . The suspect , who is being held without bail at New York 's Bellevue Hospital , is receiving a medication called olanzapine , according to a source familiar with his medical history . The drug is used to treat symptoms of schizophrenia , according to the National Institutes of Health . Pedro Hernandez admitted choking the boy after luring him into the basement of a bodega , a small grocery store , on May 25 , 1979 , police said . Etan 's remains have not been found . His attorney previously told a judge that Hernandez has a history of mental disorders , suffers from hallucinations and is bipolar . `` Mrs. Hernandez has seen her husband 's delusions and hallucinations and other mental illnesses for a very long period of time , '' Gottlieb said . He would not elaborate on the mental disorders , nor would he provide an example of what his client observed . `` She does not believe the confession at all , '' Gottlieb said . Investigators have been trying to build a case against Hernandez , looking for evidence to back up his statements to them . Police have said they have no other evidence or a motive to support his confession . A relative has said she reported that Hernandez told family members in the 1980s that he killed a boy in New York . Norma Hernandez , the suspect 's sister , said she went to police in Camden , New Jersey , back then but felt that they did n't believe her . Police have said they have no record of that report . Hernandez said her brother also told a prayer group about killing a boy . Gottlieb said he was asked to represent the wife because of her growing frustration over the case and her desire to make sure prosecutors `` understand the severity and nature of the mental illnesses . '' A spokesman for the district attorney 's office had no comment Wednesday . Rosemary Hernandez has not seen her husband at Bellevue Hospital but has spoken to him by telephone . `` It 's a very difficult time for her and her daughter , '' Gottlieb said . Pedro Hernandez 's next court appearance is scheduled for June 25 .
The search began Wednesday afternoon and lasted into Thursday morning . Police say Pedro Hernandez has confessed to killing Etan Patz in 1979 . Attorney : His wife says her husband is mentally ill and his confession is unreliable .
