The Luzerne County district attorney's office says it wants 18-year-old Shawn James Hamilton put to death if he's convicted of first-degree murder in the July shooting in Plymouth.
Hamilton and his 16-year-old half brother, Sawud Davis, allegedly killed 21-year-old Bradley Swartwood, 17-year-old Nicholas Maldonado and 15-year-old Lisa Abaunza in a robbery. Maldonaldo's 19-year-old brother was also wounded.
Hamilton and Davis pleaded not guilty at an arraignment Monday. Davis' attorneys want his case transferred to juvenile court.
Hamilton previously claimed Davis was innocent and said he fired the shots in self-defense.
