Washington, May 6 (TIWN) South Carolina was one step closer to introducing firing squads to the US state's execution methods amid a lack of lethal-injection drugs.

South Carolina last executed a death row inmate 10 years ago Thursday.  The Senate already had approved the bill in March, by a vote of 32-11. The House only made minor technical changes to that version, meaning that after a routine final vote in the House and a signoff by the Senate, it will go to Republican Gov. Henry McMaster, who has said he will sign it.  There are several prisoners in line to be executed. Corrections officials said three of South Carolina's 37 death row inmates are out of appeals. But lawsuits against the new death penalty rules are also likely.
