STARKE, Fla. -

A South Florida man convicted of killing two women by beating them with a hammer and setting them on fire during a robbery has been executed.

Robert L. Henry was pronounced dead at 6:16 p.m. after a lethal injection at the Florida State Prison.

He was convicted of the Nov. 2, 1987, murders of Phyllis Harris, 53, and Janet Thermidor, 35, his co-workers at Cloth World in Deerfield Beach.

Henry at first told authorities the crime was committed by an unknown assailant. But Thermidor lived for hours after being attacked and identified Henry to investigators.

Authorities said Henry stole $1,269 from the fabric store.
