A former Lincoln High School football coach Tuesday pleaded no contest to making racially charged threats to employees at the Ameritas Life Insurance building, 5900 O St.

Jose Jefferson, 38, is set for sentencing Sept. 1 on the felony charge of making terroristic threats.

Police arrested him and Christina Donald in March on suspicion of sending three threatening letters to Ameritas between Feb. 6 and 23. The letters, police said, made threats toward blacks.

Jefferson was a licensed insurance broker with Ameritas at the time.

He coached Lincoln High School football in 2005, leaving in spring 2006. He also had been an assistant at Nebraska Wesleyan University and Midland Lutheran College, and he was head coach of the Lincoln Capitols and Lincoln Lightning indoor pro football teams.
