Sniper Lee Boyd Malvo was sentenced to life in prison for six murders in Maryland that were part of a three-week shooting spree that terrorized the Wash-ington area in 2002.
In a brief statement, Malvo apologized on Wednesday and said he was now a different person from the impressionable teen who killed at the command of John Allen Muhammad, his accomplice and mentor.
"I'm truly sorry, grieved and ashamed for what I've done," said Malvo, his voice breaking.
Despite the contrition and Malvo's cooperation with authorities in their case against Muhammad, Montgomery County Circuit Judge James Ryan gave Malvo the maximum six consecutive life sentences without the possibility of parole.
"You could have been somebody different, you could have been better," Ryan said. "What you are, however, is a convicted murderer."
Malvo, 21, pleaded guilty last month to the murders in Montgomery County, where the series of 13 shootings began and ended in October 2002.
It is unlikely, however, that Malvo will serve time in a Maryland prison. He has already been sentenced to life in prison in Virginia for sniper shootings there and was sent to Maryland last year for trial on the condition he be returned after his case ended.
That could happen within the next several days, said Darren Popkin, Montgomery County's chief deputy sheriff.
Malvo testified in May against Muhammad, who was convicted of the same six Maryland murders and sentenced to life in prison. Muhammad was sentenced to death in Virginia.
The Maryland trial included Malvo's chilling account of his trip across the country with Muhammad. Malvo detailed the genesis of the sniper shootings, their killing methods and Muhammad's grandiose plans for more carnage.
He also confronted Muhammad, his one-time father figure, saying Muhammad had manipulated him, turning the then 17-year-old into a "monster."
Malvo and Muhammad are either suspects in or charged in shootings in four other states.
