From the Des Moines Daily News, dated July 31, 1909:
Classmate of Dr. Collins Details Story of Murder Dr. Van Vhoris at Portland Week Ago When Murder of Former Des Moines Man Occurred
Roy A. Miles Collins, who was murdered by his wife in Portland a week ago, first met the woman in the case when she called upon him for medical advice.He was attendant for some, and finally advised her to take a sea trip and seek a better climate than the northwest.The woman asked him to go along as her counseling physician, and while together on the Hawaiian Islands, the marriage took place. These details, of the meeting of the former Drake student and the woman who killed him, were related in Des Moines today by Dr. C.R. Van-Vhoris, a classmate of Collins, who happened to be in Portland at the time of the murder.He was at the home of Collins, a few moments after the shooting occurred.
Collins had few friends in Portland, almost his only confidant being Dr. Frisbie who formerly occupied an office in East Des Moines.
Collins’ first wife appeared in Portland just two weeks before the murder, and the sight of her, young, dark-eyed and handsome, increased the jealousy of the woman who knew that her husband was inclined to desert her.During the two weeks the first wife remained in Portland, she made no effort to seek Collins, but this did not prevent serious quarrels between Collins and his wife, in which the first wife was the subject of the dispute.
