Arkansas Dem Chairman Shot to Death

I can't imagine what led to this:

The chairman of the Arkansas Democratic Party was shot and killed Wednesday after a man opened fire inside party headquarters in Little Rock.

Chairman Bill Gwatney was shot “multiple times” in the upper body by a man who later escaped in a blue truck, Little Rock Police Lt. Terry Hastings said in a news conference. Gwatney died four hours later at University Hospital.

Police shot and killed the suspect, so far identified only as a 51-year-old man, after a 30-mile car chase. Police said they don’t yet know the motive for the shooting. ...

Gwatney, who was 49 and owner of three car dealerships, was elected chairman of the state party in March 2007. He served 10 years in the Arkansas state Senate and was the finance chairman for Mike Beebe’s successful 2006 gubernatorial bid.

He also was a national superdelegate who had endorsed Hillary Clinton for president, according to the Web site Sourcewatch.org.
