The Tsarnaev brothers, the alleged suspects in the Boston Marathon bombings, were reportedly on their way to New York when they hijacked a car late Thursday night, according to the New York Times.
As details of the original plan emerged, Boston police Commissioner Edward Davis said authorities believe the brothers had plans for more attacks.
When the brothers stole a Mercedes-Benz sports utility vehicle, they kept the driver hostage while they drove around attempting to use the driver's ATM card to withdraw cash.
The suspects reportedly told the driver they were going to go to New York, a senior United States official reportedly said on Sunday, though it was unclear if they told the driver what they planned to do once they arrived.
Authorities recovered four firearms they believe the suspects used, and discovered the suspects had made at least five pipe bombs.
An M-4 carbine rifle, commonly used by American forces in Afghanistan, was found in the boat where the younger brother, Dzhokhar Tsarnaev, was captured Friday night.
Boston mayor Thomas Menino told ABC News he believed the brothers acted on their own, and were not part of any larger network.
