By Casey SmithIndiana Capital ChronicleINDIANAPOLIS — A bill expanding Indiana’s execution methods was significantly amended Tuesday, Jan. 27 after lawmakers voted to remove nitrogen hypoxia as an option and added provisions on media access and mental health support. Among the adopted amendments were two from Rep. Alex Zimmerman, R-North Vernon, including a major deletion of nitrogen hypoxia as an execution method. The addition of a firing squad as an option remains in the bill along with lethal injection – the only method currently permitted in Indiana. A different amendment offered by Rep. Matt Pierce, D-Bloomington, sought to remove confidentiality protections surrounding lethal injection drugs and their sources. The move to add firing squads is an attempt to deal with the high cost of pentobarbital used in Indiana’s execution process.
