Argument over dog's droppings ends with murder charge.

A Washington, DC man is facing murder charges after a confrontation over dog poop turned violent.

Ellsworth Colbert, 56, is been accused of stabbing his neighbor, 37-year-old Robert Wright.

Witnesses say the incident happened while Wright was walking a neighbor's dog past Colbert's yard.

After a brief argument, Colbert allegedly pulled a knife and cut Wright on the hand.

Wright then grabbed a nearby shovel and struck Colbert in the head.

The men then struggled briefly before Wright walked away.

A short time later he collapsed.

When paramedics arrived they discovered multiple stab wounds.

Colbert is charged with second-degree murder.
