He wants Nebraska voters to get the same information that helped him reach his conclusions, he said.

When he arrived to the Legislature in 2009, he said, senators voted to change the method of execution to lethal injection, and promises were made that the last barrier to beginning executions was gone. Each year that went by, however, those promises were buried deeper and deeper with continuing, expensive appeals and increasing difficulty in obtaining lethal injection drugs, he said.

Nebraska hasn't executed a condemned inmate since 1997. Ten men are currently sentenced to death in Nebraska.

No matter how the November vote turns out, Coash said, executions still will not happen.

Lincoln Sen. Adam Morfeld also is part of the anti-death penalty campaign.

"The state should lead by example," he said. "If we're going to condemn killing people, we also should not kill people."

Locking away a person for life for the crime of murder both serves justice and safeguards the community, he said.
