(Hampden) Columbia County authorities have identified the Marshall man who was killed in a single vehicle crash in the Township of Hampden last Thursday. Sheriff Roger Brandner says Macros Dominguez was heading westbound on Sanderson Road just after 4pm when his Cadillac entered the north ditch line, rolled over, and struck a power poll just. The 34-year-old was pronounced deceased at the scene. Brandner says a juvenile passenger was transported to an area hospital with minor injuries. He says speed and slippery roads appear to be factors in the crash.
