[Music] do you remember the last time you spoke with your sister i do she called me sunday night at 11 30
at a train station in new york [Music] from penn station [Music] i could hear the motion from the train
station so you don't think she knew she was in danger at that time that she called you
no from the time that she called me it was poof she was gone my sister's missing like this isn't
normal there was a ping from her phone after she went missing on long island [Music]
they knew that there was something very very wrong here young lady was reported missing shannon
gilbert [Music] the missing persons unit had been involved in trying to locate this young
lady find out what happened to her we found human remains but it seemed to be wrap and burlap which didn't make any
sense everyone assumed it was shannon gilbert but it wasn't was no the crime scene gets expanded
i'm called and chief we found another set of remains they find another one and another one
we were dealing with a serial killer but they're all four foot eleven very petite hazel
green eyes this killer has a type right does he want the petite body because he wants to feel more empowered
and more in control is it easier to dispose of a lighter body investigators have found
10 sets of human remains some discovery 10 victims in all things started to click as i was
watching that i have a feeling that this is marine one of them worrying i just had a
feeling the detectives came to my house and just said that maureen has been positively identified
as one of the victims on ocean parkway i have my sister's death always in the back of my mind
the killer or killers still are loose no justice has been done it's a symbol of the complete failure of
the police department to do its job my name is jerry hart i'm the commissioner of the suffolk county
police department so it's again a very complex case but i can tell you that we are
fully committed to this investigation we believe that the belt was handled by the suspect
and did not belong to any of the victims we're working very hard that we're dedicated to this investigation
what i want most is answers and justice and i also want that the world to know like my sister mattered
