Casper Police were called to the Wyoming Medical Center around 3:50 am Saturday for a man who had stab wounds to his chest.
The man was rushed into surgery since he'd lost a significant amount of blood.
Police say they did a follow up and searching around the area near Lennox Street they say they found a large blood trail.
They added the case is still under investigation, but they have talked to some suspects.
Reports say it started as a verbal altercation between men outside of a house party and escalated to a fist fight and ultimately a stabbing.
More information will be provided later today.
