Two teenagers face life in jail, without parole, as they were charged Tuesday with the killing of a woman and her son.

According to The Associated Press, the woman was stabbed and cut about 100 times and her son had a television thrown over his head. Prosecutors said that Stafon Edward Thompson, 17, and Brian Lee Flowers, 16, both of Minneapolis were responsible for the death of Katricia Daniels, 36, and her 10-year-old son Robert Shepard.

They were charged with four counts of first degree murder.

Apparently the two teens blamed each other: Flowers said that Thompson killed Daniels because he wanted her car and he also killed Daniels' son with the TV set. Thompson said that Flowers killed Daniels because he wanted money and he wanted Daniel’s son dead because he was a witness.

Hennepin County Attorney Mike Freeman said that the only thing stolen was Daniel’s mobile.

“We don't know why this murder was committed and we may never know why. The level of violence associated with this crime is difficult to comprehend and difficult to imagine,” said Freeman, according to The Associated Press.

Last Thursday, Joseph Williams, Daniels’ boyfriend, found Daniels and her son dead in their home. His 1-year-old daughter was not injured. Apparently the suspects and the victims knew each other, as they were friends with Daniels’ son from Chicago. A neighbor said that they used to call her “Mom,” reported KARE.

Authorities found two knives and a golf club in Daniels’ house and another knife in a garbage can. They arrested the two teenagers on Friday. The family and whole neighborhood were in shock and couldn’t believe that this could have happened. About 200 people gathered Monday night to remember the victims, reported KARE.

Williams was very affected, but managed to thank the crowd and the police for their work.
