An elderly woman crossed over the double yellow line on Route 155 Sunday, causing a two-car crash that sent both her and the other driver to Albany Med. The other driver was Joseph Cotazino, 61, a well-known figure in Voorheesville, who is the leader of the Orchard Park Neighborhood Association, which is very active in local charity work. Gladys Chamberlain, 78, also of Voorheesville, may have had a medical event before crashing head-on into Cotazino's vehicle, say officials from the sheriff's office. The cause of the crash is under investigation.
