The North Dakota Stockmen's Association says a reward being offered for information in the shooting deaths of some cattle has grown to $13,000 — the largest such reward in state history. Dakota Community Bank and two of its owners have contributed $3,000 to push up the reward fund. The fund began with $1,000 from the Stockmen's and $9,000 from the owners of the nine animals shot in Oliver County on the Fourth of July. The reward is being offered for information that leads to an arrest and conviction.
