LINCOLN, Neb. (AP) — A group formed to oppose Nebraska’s death penalty referendum is broadcasting its message on the radio.

Nebraskans for Public Safety announced a statewide radio advertising campaign set to begin Thursday as part of its outreach to voters. The group has also bought airtime on television stations throughout the state.

Danielle Conrad, a spokeswoman for the group, says the death penalty is broken and life in prison is a better alternative. Nebraska last executed an inmate in 1997.

The group Nebraskans for the Death Penalty has until Aug. 27 to gather enough signatures to place the question on the 2016 general election ballot.
