A Tennessee man convicted of kidnapping, raping and murdering a couple on a date has been sentenced to death.

The defendant, 28-year-old Lemaricus Davidson, showed no reaction Friday as jurors announced the death sentences for the murders of 21-year-old college student Channon Christian and her 23-year-old boyfriend, Christopher Newsom.

Davidson was found guilty of abducting the couple in Knoxville during a 2007 carjacking by several armed men.

Both were raped, Newsom was fatally shot and Christian suffocated after she was choked and stuffed in a garbage bag and trash can.

Davidson's brother was convicted in the same attack in August and is serving life in prison without parole. Two other defendants from Kentucky are awaiting trial.
