STARKE, Fla. -

A former escort service owner convicted of killing two women in the 1980s has been executed in Florida for the death of one of those women, an exotic dancer.

Forty-nine-year-old Marshall Lee Gore was pronounced dead at 6:12 p.m. Tuesday following an injection at Florida State Prison, authorities said.  He had spent 23 years on death row.

Gore was sentenced to die for the March 1988 killing of Robyn Novick, a 30-year-old exotic dancer whose nude body was found in Miami-Dade County. Gore also was convicted of killing another woman.

Tuesday was the fourth time Gore's planned execution was scheduled this year. Twice, courts put it on hold due to insanity claims and once because of a conflict with one of Attorney General Pam Bondi's political fundraising events.
