CORVALLIS (AP) - A bicyclist has been charged with manslaughter after his bicycle went past a stop sign and struck and killed a 71-year-old woman, police said Monday.

Jean Calder died at Good Samaritan Hospital after she was struck Friday night as she crossed a street at an unmarked crosswalk, Corvallis police Capt. Ron Noble said.

Calder had the right of way when the bicycle struck her, police said.

Christopher A. Lightning, 51, was charged with manslaughter and reckless driving. The incident was serious enough to warrant criminal charges, Noble said.

"A car and a bicycle are both vehicles and if they are operated in a way that could be criminal then charges are filed equally in both situations," he said.
