Robert Rolfe, a six-year Harvey police veteran, was shot twice. He was in "stable" condition while preparing for surgery Monday with family and fellow officers at his side at Ingalls Memorial Hospital in Harvey, according to the statement.
Rolfe and his wife of five years have a 5-month-old son, the statement said. The family "wishes to express gratitude for the continued outpouring of support and well wishes," the statement said.
