Police say a West Valley man stabbed a friend after an argument Saturday morning.
The 36-year-old was booked into Salt Lake County Jail on suspicion of aggravated assault. Police say he was drinking with two male friends at his house near 4000 S. 3100 West when his girlfriend came home from her job at a bar, and the two then began to argue. The man's guests intervened and "told him to knock it off," said West Valley City police Lt. Lamont Cox, and for at least a while he calmed down.
But a second fight broke out about 7:51 a.m., and police say the suspect grabbed a kitchen knife and stabbed one of the men, a 19-year-old, in the back.
