I also found an earlier article at the time of the murder (below, right) which claims Shortlidge's was suffering from "the grip", which supposedly caused his insanity. The grip is an old term for the flu but as we know today, influenza does not last as long as what this article from the New York Times is claiming. Supposedly, he'd been suffering from it before his wedding in November and then killed his wife the night of December 31. The flu can cause pneumonia which may extend the illness but someone suffering that long from pneumonia would not have the strength to be walking about and murdering someone. Furthermore, neither influenza or pneumonia are not known to cause insanity as far as I'm aware!

Only weeks after his release, Shortlidge applied for a passport. Though he remained a resident of Pennsylvania for some years, he eventually moved to England for some time (he can found on the 1911 Census) with his son, who was married there in 1906. Shortlidge left England and returned to New York in 1914, where he was also living by 1930.
A very interesting case that might warrant further investigation for those interested in the history of mental illness and/or crime.
