A 51-year old Centralia man had to undergo surgery for internal bleeding, after an argument over a pair of shoes Tuesday night apparently led to his stabbing.  According to police reports, Michael Mansker was stabbed in the stomach and 27-year old Robert Vorce of Iuka, has been charged with home invasion and aggravated battery in connection with the stabbing incident.  Police say members of the Vorce family showed up at Mansker’s home and an altercation took place.  Mansker was confronted by Vorce with what Mansker told Centralia police was a silver butterfly knife.  Mansker reported that Vorce shoved him multiple times and when he finally got out the front door, he noticed he was bleeding.  Police say Mansker underwent surgery to stop internal bleeding.
