WILKES-BARRE -- Two brothers from Philadelphia pleaded guilty to and were sentenced for several 2012 Luzerne County murders.
Shawn Hamilton is headed to prison for the rest of his life.
He pleaded guilty to murdering four people in Luzerne County in 2012.
First, shooting a man in the head in Wilkes-Barre and one day later, three people in Plymouth because he did not want to leave witnesses to a drug deal.
The victims were 21 years old, 17 years old and 15 years old.
Investigators said Hamilton also shot and almost killed a fourth person in Plymouth.
For the killings, Hamilton received four life sentences.
"This case will never be forgotten among the law enforcement and prosecution in Luzerne County. The image of a 15 year old covering her face, hiding from a monster, screaming and pleading for her life will never be forgotten," said Luzerne County District Attorney Stefanie Salavantis.
Hamilton's brother, Sawud Davis pleaded guilty to third degree murder, admitting he was part of the Plymouth killing spree.
Davis was 16 years old at the time.
He was sentenced to 20 to 40 years in lock-up.
In court, the brothers heard from the family of their victims, who called them "cowards."
The brothers had a chance to speak as well.
Sawud Davis said in part, "Things happen. I had nothing to do with this."
Shawn Hamilton said, "I'm not really sorry because if I was sorry, I wouldn't have did it in the first place."
For some in the courtroom, hearing the killers talk was unbearable.
"They have no remorse, they're not sorry. They are monsters, what they had to say, it just shocked me," said Kayla Otero, whose boyfriend was one of their victims.
