Dec. 18 (UPI) -- Florida upped its execution record to 19 after enforcing the death penalty via lethal injection on Frank Athen Walls, who was pronounced dead at 6:11 p.m. EST on Thursday.

Walls, 58, was convicted of two counts of murder, two counts of kidnapping and one count each of burglary and theft during a 1988 trial, the Orlando Sentinel reported.

Walls apologized for the murders before his executioners applied the lethal dose of three drugs as 23 witnesses observed the procedure from their seats.

"Good evening, everyone. I appreciate the opportunity to say what's on my heart. If any of the members of the family are here, I am sorry for all of the things I did, the pain I caused and all of that you have suffered all these years," Walls said.
