Does anyone have any information concerning the killing of Mr. Slack by a Dunn in ROger Mills County Okla around the turn of the century? They were partners in a ranch there having recently established it after both moved from Henrietta Texas. They had an argument and when Slack got off his horse to open a wire gate, Dun shot him in the back. Always wondered if Mr Dunn was part of the Dunn Brothers of Cimmaron fame. My daughters are descendants of the Slacks.

Elbert, here is some information:
SLACK, MALE-10 Jul 1919, Elk City Newspaper, Elk City, Beckham Co, OK: KILLS HIS PARTNER
For about fifteen years Messrs. Dunn and Slack of Crawford (Roger Mills County) were partners in the cattle business. Last Thursday Dunn killed Slack as they were returning from Strong City. It seems they had desolved(sic) partnership, and had been to town that day, trying to fix up the papers. Returning home, so says Dunn, he remarked as they could not agree on a settlement, that they would have to have a receiver appointed. He said at this Mr. Slack pulled out a gun and pointed to him saying that "this will settle it." Dunn then shot him, killing him. He sent word to the sheriff and hid out, but was afterwards found. Dunn is married.

No christian names given and no disposition on Dunn.
