STARKE, Fla. (AP) — Florida put to death one of its oldest prisoners in its history on Tuesday, a 74-year-old convicted murderer who was one of three older inmates scheduled for execution within the span of a month in the nation’s busiest death penalty state.

Dennis Sochor was pronounced dead at 6:16 p.m. following a three-drug injection at Florida State Prison near Starke. He was convicted of killing Patricia Gifford on Jan. 1, 1982, just hours after meeting the 18-year-old woman at a New Year’s Eve party.

Sochor was already strapped to a gurney with an IV in his arm when the curtain to the death chamber went up at the 6 p.m. execution time. Asked by the warden if he had any last words, Sochor said he did.

He apologized several times to the Gifford family, saying he was “deeply sorry” for his actions and thanked his own loved ones for their support over the years.
