Bradley Swartwood, 21, Nicholas Maldonado, 17 and Lisa Abaunza, 15, were fatally shot after police say a drug deal backfired between Swartwood, Maldonado and Shawn Hamilton and Sawud Davis, 18 and 16-year-old step brothers from Philadelphia who were staying at an apartment in Nanticoke.
Arrest papers reveal Hamilton claiming his younger stepbrother drew a 40 caliber pistol and fired between eight to ten shots.
The Luzerne County Coroner's office released word late Monday the victims each died from multiple gunshot wounds.
Funeral arrangements are pending for Swartwood, Abaunza and Nicholas Maldonado.
19-year-old Daniel Maldonado remains in critical condition at Geisinger Wyoming Valley Hospital.
Hamilton and Davis are scheduled to appear for a preliminary hearing on July 18.
