Scott's sentence was part of a plea agreement reached with the Prince George's County State's Attorney's office under the Alford agreement. Per the Alford agreement, Scott did not admit to his guild in the crimes, but did acknowledge that the evidence against him was very strong, according to The Washington Post.
“This was an absolutely horrific murder by a cold-blooded killer who is the worst type of criminal that we have ever come in contact with,” State's Attorney Angela Alsobrooks said said in a statement.
“Today, we have ensured that Mr. Scott will never get out of prison and the families of his victims can continue to heal and move forward with their lives.” Alsobrooks stated.
Prosecutors believe that Scott strangled the Dewitts in their home, and then placed their bodies in a stolen car and set the car on fire a few miles
from the residence.
Prosecutors also believe that Scott is guilty of the 2008 slaying of 46-year-old Bowie resident Velma Butler, who was shot to death before her home was set on fire. He is also suspected in the 2009 killings of Karen Lofton, 45 and her 16-year-old daughter Karissa, though he will not be prosecuted for these three murders, reported The Wasghington Post.
Police believe that Scott tracked his victims, including the Dewitts, using computers at UPS, where he was employed at the time of the crimes, reported NBC Washington.
Scott is currently serving 100 years in prison after being convicted last year with series of home invasions, including one in Bowie.
According to a statement from the Department of Justice, Scott broke into a Bowie home via an unlocked basement window in April 2009.
He allegedly held the couple and their three children at gunpoint while an accomplice took the victims' debit card and withdrew funds from their bank account.
When his accomplice returned with the money, officials said, he and Scott proceeded to steal various items from the home, including a 2004 Mercedes S-500.
