LINCOLN, Neb. (AP) — The Nebraska State Patrol is still investigating five “concerning calls” to legislative offices in the heat of a debate over the death penalty, but the calls haven’t been deemed a criminal matter.

Spokeswoman Deb Collins said Thursday that three state senators reported calls to their legislative offices in recent days. Lawmakers voted Wednesday to abolish capital punishment, overriding Gov. Pete Ricketts’ veto.

Collins says investigators have concluded so far that the calls do not rise to a criminal matter.

One of the phone messages was left at the office of Sen. Heath Mello, a death penalty opponent. Mello, of Omaha, says the caller didn’t explicitly make a threat but suggested that he should be harmed because of his vote.
