Prosecutors charged Dat Nguyen with second degree murder for the stabbing death over the weekend.  Police say he stabbed Tan Nugyen at a party in the 2000 block of S. White Oak Road early Sunday morning.

Police say there was a party with around 30 people at that address.  Police say 27-year-old Tan Nguyen and 29-year-old Dat Nguyen (the two are not related) got into an argument. At one point, Tan's brother pulled out a gun.  That's when police say Dat stabbed Tan. 

Tan was taken to the hospital where he later died.

Police would not say what the two were arguing about.

Eyewitnesses helped police identify the suspect, who was arrested later at his house.
