An outspoken critic of the death penalty says 鈥� though yesterday鈥檚 lethal injection of Ronald Phillips was problem-free -- he worries that won鈥檛 be the case with the more than two-dozen executions scheduled over the next three years.

Ohio Public Defender Tim Young says no other state has as many executions set out as far into the future as Ohio has. And because the three drug mixture the state used for the first time with Ronald Phillips includes midazolam, he鈥檚 very concerned about problematic executions ahead.

鈥淲e鈥檒l have another one of those. The science on midazolam being involved in this is so clear, it is simply a matter of time,鈥� he said.

Philips was the first killer to be executed in Ohio since the 2014 lethal injection of Dennis McGuire, who gasped and choked for several minutes before he died. The state prisons department said it concluded McGuire鈥檚 execution was humane, though the state did change its drugs going forward.
