BOSTON (NEWSCHANNEL 3) - Much of the city of Boston remains on lockdown at this hour, as one of the suspects in the marathon bombing is on the run.
19-year-old Dzhokhar Tsarnaev was last seen overnight during a violent shootout that killed his older brother Tamerlan Tsarnaev, near Watertown, Massachusetts.
An MIT officer was also killed in the gunfire.
The brothers are reportedly from the Russian region near Chechnya, and lived in the United States for at least one year.
On Thursday evening, the FBI released pictures of the two bombing suspects.
Around 10:20 p.m., shots were fired on the campus of the Massachusetts Institute of Technology in Cambrige.
At near 10:30, an MIT campus officer was shot--he eventually succumbed to his injuries.
A short while later, two armed men carjacked a vehicle in Cambridge, and a chase ensued.
An explosive device was thrown from the vehicle, and gunfire was exchanged. One suspect--Tamerlan Tsarnaev--was killed.
At around 1:00 a.m., gunshots and explosions were heard in Watertown.
By 4:30 a.m., authorities were asking residents of Boston to stay indoors.
Adrianna Diaz is at the scene of the bombing with a closer look at those events, and the latest developments in the manhunt.
