Family members whose loved ones were killed by a Florida death row inmate say they forgave him long ago and that his execution isn't about justice.

Curtis Windom, 59, was executed by lethal injection on Thursday, Aug. 28, for the 1992 triple murder of his friend, his girlfriend and his girlfriend's mother in a shooting rampage in Winter Garden, part of metro Orlando. Windom was pronounced dead at 6:17 p.m. ET.

Windom's execution is the 11th so far this year in Florida, which is putting more inmates to death than any other state. It's also the 30th execution in the U.S. this year so far, a 10-year high largely being driven by the Sunshine State amid a nationwide expansion of execution methods.

Many of the family members of the three people Windom killed were vehemently opposed to the execution. The victim family members, some of whom are also related to Windom, expressed outrage that Florida dismissed their request to spare his life because they had forgiven him, loved him and didn't want to see him die.

The execution was "a dog-and-pony show," the family members wrote in a statement distributed by Floridians for Alternatives to the Death Penalty.
