Henderson, Ky. ? Murder warrants were issued Friday in Kentucky for a couple accused of kidnapping the woman’s 9-month-old son from a social worker who was later found dead, authorities said.

Renee Terrell and her boyfriend, Christopher Wayne Luttrell, were charged Friday with fleeing Kentucky to avoid prosecution, which is punishable by up to five years in prison and a fine up to $250,000.

Terrell, 33, and Luttrell, 23, are also suspects in the death of social worker Boni Frederick, 67, said Henderson, Ky., police Sgt. John Nevels. They will be formally charged with murder after being returned to Kentucky, Nevels said.

At an extradition hearing Friday on the kidnapping charges, they waived their right to a second hearing that would have determined whether federal bond was set.

They are accused of kidnapping Terrell’s infant son, Saige, on Monday from Frederick, who had taken the boy to Terrell’s home in Henderson for a visit.

The baby had been removed from Terrell’s custody when he was 13 days old because of neglect, police said.

Frederick was found beaten to death at the house later that day.
