(KETK) — UPDATE :
Boston Police Officials say second suspect in Boston bombing alive and in custody.
The two suspects have been identified as brothers from the Chechen Republic.
19-year-old Dzhokhar Tsarnaev and 26-year-old Tamerlan Tsarnaev.
More than a million Boston residents in the city and suburbs were ordered to stay in their homes Friday morning after a night of events with the suspects.
"It is important that folks remain indoors and not open the door. Keep the door locked. Do not open the door unless there is uniformed identified enforcement officer standing outside asking to come inside," said Massachusetts Gov. Deval Patrick.
The FBI released photos and videos of two suspects investigators believe are behind Monday's Boston Marathon bombings at 5 p.m... Thursday night.
Around 10:20 p.m..., a robbery took place at a 7 Eleven convenience store in Cambridge, near the Massachusetts Institute of Technology campus.
Ten minutes later, law enforcement officials say the brothers shot and killed a MIT police officer,Sean Collier, 26, in his car.
After the FBI released their photos, the brothers tried desperately to flee.
They carjacked a Mercedes SUV and told the driver, at gunpoint they were the Boston Marathon bombers and had just killed a campus security officer.
Officials say they stopped at three different ATM machines to withdraw money from the driver's debit card.
The brothers let the driver go, unharmed at a gas station in Cambridge.
As they sped out of Cambridge toward Watertown, a wild police chase started following the car.
Authorities say the suspects threw explosives and grenades from the car as more than 40 police officers followed the stolen car into Watertown.
The suspects and the police exchanged a long gunfire fight, seriously injuring one of the suspects and a transit police officer, 33 year old Richard Donohue.
The fire fight ended when Tamerlan Tsarnaev,the older brother, ran toward police officers with an explosive strapped to his chest.
Dzhokhar,who was wearing a white hat in the photos, drove the SUV through a line of police, and ran over his brother's dead body, around 4 a.m.. Friday morning and ran away.
Authorities confirmed Tamerlan is dead and Dzhokhar is still on the loose.
"I say, Dzhokhar! If you're alive, turn yourself in! And ask for forgiveness from the victims, from the injured, and from those who left, ask forgiveness from these people," said their Uncle Ruslan Tsarni.
