Boston and several of its suburbs are on lockdown Friday morning.
One of the Boston marathon bombing suspects, Tamerlan Tsarnaev, was killed early this morning after he and his accomplice—his brother, Dzhokhar Tsarnaev—robbed a 7-Eleven, killed a police officer, carjacked an SUV and hurled explosives in a fight with law enforcement, per NBC News.
Police have now launched a massive manhunt for Dzhokhar, and authorities are conducting door-to-door searches and urging residents to take shelter and remain in their homes today.
As the manhunt continued, celebrities took to Twitter to send their love, light and well-wishes to those affected.
Alec Baldwin: "The effects of terrorism on our society will get worse before [they] get better. The presence of police as a paramilitary force in our society will now grow to new levels. Cameras, bomb-sniffing dogs, checkpoints, etc, will expand exponentially the notion that someone capable of brutal, cold-blooded and random killing walks openly in public will further shape our lives. [The] cost of security measures will skyrocket. Further diverting funds meant for other, equally important goals, in American society. Tweeting a simple observation re our society always yields 1 benefit. I can block all right-wing idiots that come out of their foxholes. The bravery and effectiveness of police is a blessing. Their presence is welcome, in times like these. Yet it highlights something."
Harry Shum Jr.: "Praying for everyone in Boston. I am speechless...."
Eliza Dushku: "It doesn't get closer to home than this. #Watertown, MA~ #hometown God, please, everyone be safe. #Waterdown PD we are all sending you prayer... Born&raised in #Watertown.
