Ellsworth Colbert, campaign volunteer, fatally stabs neighbor over dog droppings

Ellsworth Colbert, accused of stabbing to death his neighbor, Robert Wright.

Ellsworth Colbert, a volunteer on Kevin Chavous's D.C. Council Campaign, has fatally stabbed his neighbor, 37-year-old Robert Wright, police say.

Colbert has been charged with second degree murder while armed, police say.

Councilmember Yvette Alexander tells ABC7 that while details remain sketchy, it appears a dog belonging to either the victim or suspect defecated on the other's property, starting an argument.

Kevin Chavous Sr., father of the candidate, says Colbert has been an active volunteer on the campaign and has wanted a bigger role but the campaign would not give it to him.
