The Kentucky Supreme Court has ruled that the state's lethal injection method is constitutional, possibly clearing the way for at least two inmates to be executed.

Kentucky Death Row inmates, Thomas Bowling and Ralph Baze, challenged the state's method of executing condemned prisoners, saying the drug formula used amounted to cruel and unusual punishment.

The ruling handed down today in Frankfort affirms a prior ruling by Franklin Circuit Judge Roger Crittenden. The 52-year-old Bowling was sentenced to be executed for killing Edward and Tina Earley and shooting their two-year-old son outside the couple's Lexington dry-cleaning business in 1990.

The 49-year-old Baze was convicted of killing Powell County Sheriff Steve Bennett and Deputy Arthur Briscoe during an attempted arrest by the officers in 1992.
