COLUMBIA, S.C. (WIS) - A man who police believed shot and killed his neighbor in the Eau Claire neighborhood of Columbia is now also dead, Columbia Police Chief Skip Holbrook said.

In the middle of the afternoon on Dec. 20, 57-year-old Harriet Richardson was found shot near her home on Marsteller Street.

She died at the hospital just days before her 58th birthday, police said.

Officers zeroed in on her neighbor as a suspect, saying Mattiyah Henderson had a “personal vendetta” of some sort against Richardson.

On Dec. 26, police tracked Henderson down to an area near Monticello Lake in Fairfield County. As officers got close to him, they said he pulled out a gun and shot himself. He died at that scene.

Holbrook said police believe the gun Henderson used to shoot himself was also the gun used to kill Richardson.

Police did not share the nature of the dispute between Richardson and the suspect, saying it was part of an open investigation.
