An explosion of gunfire began early on Friday morning in Watertown, Massachusetts as police engaged in a shootout with the two suspects in the Boston marathon bombing. By the time the fire fight was over, Tamerlan Tsarnaev was dead, and his brother, Dzokhar Tsarnaev, was on the run. Watertown - and later Boston - were put in lockdown. Armoured vehicles, helicopters, SWAT teams, bomb squads and K-9 units joined members of the National Guard and thousands of local, state and federal police. Brent speaks to Jonathan Peck
, a Watertown resident who heard the firefight and then remained locked in his house, where we reached him Friday afternoon.
