Mary Murphy interviews Suffolk County D.A. Ray Tierney 
1 Year after the Long Island Serial Killer arrest

Raymond Tierney, District Attorney of Suffolk County, granted Mary an interview on July 10, 2024, three days before the first anniversary of Rex Heuermann's arrest in the Long Island Serial Killer case (LISK). 

Part 1

District Attorney Tierney insists the 60 year old architect, a married father of two, carried out his alleged crimes alone.

As of June 2024, Heuermann is charged with six murders, including the 1993 mutilation of Sandra Costilla in Southampton. 

There was important hair DNA recovered from her crime scene but no DNA from seminal fluid.

Part 2

I asked District Attorney Tierney about male bodies found near Manorville, Long Island in the early 2000's that are close to sites where the torsos of two female Gilgo victims were recovered.
