The Boston Marathon bombing suspects armed with explosives and guns battled law enforcement officers in a Bostonsuburb early Friday morning, unleashing chaos until cops took one of the men into custody and the other fled, law enforcement sources said.

Officials later said the suspect taken into custody died and authorities identified the man on the run as the "white-hat" suspect, referencing photographs released by the FBI Thursday. Authorities warned he should be considered armed and dangerous. The standoff in Watertown, Mass., erupted shortly after the fatal shooting of a Massachusetts Institute of Technology police officer.

A transit police officer wasalso wounded in the Water town fire fight, officials confirmed to NBC affiliate WHDH.

Officials in Watertown were warning residents to "stay in theirhomes and not open their doors unless a police officer is there."
"There is a terrorist on the loose," said one officer at an impromptu press conference at about 4:30 a.m. ET.

The suspect at large believed tobethe man who physically placed thebags containing the homemade bombs which killed 3 and injured 170 on Monday was described as"dressed in a grey hoodie, light skinned male, brown curly hair." Watertown resident Andrew Kitzenberg described the earlier police standoff outside his house. “They engaged in gunfire for a few minutes,” Kitzenberg said. “They were also utilizing bombs, which sounded and looked like grenades, while engaging in the gunfight. They also had what looked like a pressure-cooker bomb.”

The gunmen used"bombs that looked like grenades," Kitzenberg told NBC News.
Kitzenberg said when he looked out the window he saw two people taking cover between a black Mercedes SUV and a sedan, and watched them shooting 70 or 80 yards toward six Watertown police vehicles.

He said the pair took cover behind the Mercedes SUV and were shooting westward toward the police officers. They also had backpacks. “It was a firefight,” he added. “There was a long exchange of gunfire.”

Surely they must be more than suspects but the actual perpetrators of this crime. The police should not spare any efforts to bring them to book.
