DEPUTY SHERIFF BLAIR RETURNS FROM HIS TRIP TO DILLON
Deputy Sheriff Blair returned yesterday from Dillon, Mon. where he went in company with Sheriff Livingston of Grant County, Or., after John Hamblet, alias Bob Grant. J.M. Box was found with him safe and sound. A women of the name of Jones was also found with Hamblet, who it is said followed him from Baker City, Or. where she left a husband.
J.M. Smith, the undersheriff at Dillon was sitting on the courthouse steps one morning when he noticed a team come driving into town, by the only street the town possesses. He saw the man was very tall, and having had the description of Hamblet, sent him only a day or so before, exclaimed "there's my man" as it proved to be.
So many questions, about that article, so few details!
Okay, so I found another article it is very long. I cannot contact you through ancestry to send it, as I am not currently a subscriber. However, I think you can contact me, and then I can write back. He apparently was wanted for the murder of Ben Gammey, of Rock Creek, Grant County, Oregon on February 14, 1894. The date of his arrest does not match with his wedding date, but other details seem to match.
