Sampson was convicted in 2004 of killing three people over a week in 2001.
Confessed murderer Gary Lee Sampson has again been given the death penalty by a federal jury during his sentencing retrial for a weeklong crime spree in 2001.
A jury sentenced Sampson, 57, to death for the murder of Jonathan Rizzo. He received life in prison for the murder of Philip McCloskey, according to The Boston Herald and the U.S. Attorney's Office.
This was the second time a federal jury decided that Sampson should die for his crimes.

Sampson was convicted in 2004 of killing three people during carjackings over a week in 2001. He was given the death penalty.
But, that sentence was overturned by a judge in 2011 after authorities learned that one of the jurors in the trial omitted details on her background, preventing Sampson from receiving his right to be tried by a fair and impartial jury.
A new trial ordered, which began in November.
Prosecutors again asked for the death penalty. Sampson is able to be sentenced to death despite Massachusetts' ban on the death penalty because his case is in federal court.

Sampson lived in Abington when he committed the murders and was known as a "drifter." In his 2004 trial, Sampson pleaded guilty to carjacking and killing two men in Massachusetts.
Those men were Philip McCloskey, 69, and Jonathan Rizzo, 19, both of whom he carjacked. Sampson had both drive to secluded areas where he stabbed them to death.
During the same weeklong crime spree, Sampson also killed Robert "Eli" Whitney in New Hampshire. Sampson strangled Whitney, 58, to death after breaking into a Lake Winnipesaukee vacation home. He was separately convicted of that killing.
Sampson's defense attorneys argued against the death penalty, saying that Sampson had a history of mental illness.
It was also disclosed in recent years that Sampson has advanced cirrhosis of the liver.
Sampson was the first person sentenced to death in Massachusetts under the federal death penalty statute. The state's death penalty as abolished by the Legislature in 1984.
