A man allegedly armed with a gun and a deep-seated racial vendetta was barreling down busy streets in Brockton in a van in January 2009.
According to police reports at the time, Keith Luke had earlier raped and shot two Cape Verdean sisters, killing the younger one, and then gunned down a homeless man. Police were scrambling to apprehend him.
Brockton police Officer William Devine was in his cruiser and tried to stop traffic as Luke raced through, allegedly firing at the officer. As Luke speeded on, Officer James Cronshaw, who was on foot, also tried to stop traffic before exchanging gunfire with him, according to the state Executive Office of Public Safety and Security.
Moments later, Luke crashed and was arrested. He is now awaiting trial on charges that include first-degree murder.
