Two people accused of killing a social worker in western Kentucky could face the death penalty if convicted.

Henderson County Commonwealth's Attorney Bill Markwell filed a notice of intent this week to try the cases against 33-year-old Renee Terrell and Christopher Luttrell, 23, both of Henderson, as capital cases. A Henderson County grand jury charged the couple with murder, kidnapping, first-degree robbery and the theft of over $300.

"We have reviewed the evidence in its entirety. We believe the conduct of the defendants of murder and robbery raises (the case) to the level where the jury should consider sentences more serious then life in prison," Markwell told The (Henderson) Gleaner on Thursday.

Terrell and Luttrell are accused killing Boni Frederick, 67, on Oct. 16 and kidnapping Terrell's infant son. Prosecutors say the couple stole jewelry off of Frederick's body and stole her car.

Both have pleaded not guilty to charges of murder, kidnapping, robbery and theft.

First-degree robbery is considered an aggravating circumstance that makes the case eligible for the death penalty.
