WATERTOWN, Mass. - Police say the Boston Marathon bombing suspects used their carjacking victim's ATM card before a gunfight with authorities.
Watertown Police Chief Edward Deveau says the suspects also told the carjacking victim they bombed Monday's race and killed a police officer.
A car chase and shootout ensued when a Watertown officer saw the two brothers in different cars and followed them.
The suspects exchanged gunfire with police, wounding a transit officer and tossing a bomb and two hand grenades.
Deveau says Tamerlan Tsarnaev ran out of ammunition and police tackled him, before Dzhokhar Tsarnaev drove the carjacking victim's Mercedes toward them.
Police dove out of the way and the Mercedes dragged the other suspect's body down the block.
Police negotiated Dzhokhar Tsarnaev's surrender after a resident saw him in his boat hours later.
