On April 15, 2013, two homemade bombs detonated 12 seconds and 210 yards (190 m) apart at 2:49 p.m., near the finish line of the annual Boston Marathon, killing three people and injuring several hundred others, including 16 who lost limbs.
Why It's Tragic
- 3 people are killed and 16 are injured.
- Dzhokhar and Tamerlan Tsarnaev are responsible.
- It was later turned into a manhunt.
