FARGO, N.D. (AP) — Slain Fargo police officer Jason Moszer is being remembered as a hero who was fulfilling his mission when he was gunned down in a downtown Fargo neighborhood.

Fargo Chief of Police David Todd told thousands of mourners at Scheels Arena Monday that Moszer was a "cop's cop" who was committed to saving others. Todd says Moszer was helping victims of domestic violence and protecting residents from a dangerous person when he was shot and killed.

Todd says police are keeping an empty seat where Moszer sat during briefings. Todd says Moszer's call sign, "Edward 143," will no longer be used by Fargo police.

The funeral for Moszer was officiated by the Rev. Kevin Kloster, a onetime Fargo police chaplain. Kloster also performed the wedding ceremony for Moszer and his wife, Rachel.

Kloster says Jason Moszer was "a warrior, a hero, a husband, a father, a son and so much more."
