On December 4, 1975, Gaskins led police to land he owned in Prospect, where police discovered the bodies of eight of his victims. Gaskins was tried on eight charges of murder on May 24, 1976, found guilty on May 28 and sentenced to death, which was later commuted to life in prison when the South Carolina General Assembly's 1974 ruling on capital punishment was changed to conform to the U.S. Supreme Court guidelines for the death penalty in other states. On September 2, 1982, Gaskins committed another murder, for which he earned the title of the "Meanest Man in America". While incarcerated in the high security block at the South Carolina Correctional Institution, Gaskins killed a death row inmate named Rudolph Tyner, who had received his sentence for killing an elderly couple during a bungled armed robbery of their store in Burgess. Gaskins was hired to commit this murder by Tony Cimo, the son of Tyner's victims. Gaskins initially made several unsuccessful attempts to kill Tyner by lacing his food and drink with poison before he opted to use explosives to kill him. To accomplish this, Gaskins rigged a device similar to a portable radio in Tyner's cell and told Tyner this would allow them to "communicate between cells". When Tyner followed Gaskins' instructions to hold a speaker (laden with C-4 plastic explosive, unbeknownst to him) to his ear at an agreed time, Gaskins detonated the explosives from his cell and killed Tyner. He later said, "The last thing he [Tyner] heard was me laughing." Gaskins was tried for Tyner's murder and sentenced to death. It was the first time in the history of South Carolina that a white man was sentenced in 1982 to death for the murder of a black man. While on death row, Gaskins claimed to having committed between 100 and 110 murders, including that of Margaret "Peg" Cuttino, the 13-year-old daughter of then South Carolina State Senator James Cuttino Jr. of Sumter. Gaskins was executed on September 6, 1991, at 1:10 a.m. in the electric chair, hours after he tried to kill himself by slitting his wrists. His last words were: "I'll let my lawyers talk for me. I'm ready to go."
