BOZEMAN, Mont. -

A man accused of stabbing another man outside a Gallatin Gateway bar in 2011 is on trial this week at the court house.

Witnesses took the stand Tuesday to give their account of what happened that night in October outside Stacey's Bar.

They said a wedding party was celebrating in the bar, but an altercation broke out between them and another group.

That's when witnesses said Mark Paul Logan pulled out a hunting knife and stabbed one of the men in the wedding party, then fled.

"Pretty much wrapped his hands around his waist, kind of to bring him down to the ground" said one witness, recounting what he saw. "And as he did that, I watched him start stabbing him in the back."

A tip led to Logan's arrest at a laundromat in White Sulpher Springs, about three weeks after the incident.

Logan has a previous conviction for second degree manslaughter for stabbing a co-worker to death in Kentucky in 1998.

The trial will continue Wednesday.
