'Pee Wee'

In November 1970, Gaskins committed the first of a series of confirmed murders, primarily people whom he knew and killed for personal reasons. His first confirmed victims were his own niece, Janice Kirby (aged 15), and her friend, Patricia Ann Alsbrook (aged 17), both of whom he beat to death. He said he was enraged at their drug abuse, while others say he was attempting to sexually assault them in Sumter.

He poisoned Martha Ann Dicks ("Clyde"), aged 20, in March 1971 either because she said Pee Wee was the father of her unborn child, or because she was an alleged drug dealer who supplied Kirby and Allsbrook with drugs.

Gaskins was an overt racist and he raped and drowned both Doreen Hope Dempsey, 22, and her two-year-old daughter, Robin Michelle Dempsey in June 1973. Gaskins had befriended Doreen Dempsey several years prior and was angry upon hearing she had become pregnant a second time with an African American man. She had been living with Gaskins's friend Johnny Sellers and his brother Carl Sellers in North Charleston, South Carolina. They brought her to Gaskins's home in Prospect, and left her there to speak with Gaskins about staying with him for a short time while she was pregnant. Upset that Doreen was having a second biracial child, Gaskins responded by walking her to his backyard pond where he drowned both the mother and her toddler.

In June 1974, Gaskins shot his friend and criminal associate Johnny Sellers, aged 36, in the back of the head, and stabbed to death Johnny's ex-girlfriend Jessie Ruth Judy, aged 22, after Sellers asked for money he was owed from the sale of a stolen boat. Gaskins feared Sellers would reveal Gaskins was also involved in an auto theft ring. Jessie Judy was murdered at the same time because she could have told police about Gaskins's criminal activities, including murdering her boyfriend, Johnny Sellers.

Silas Barnwell Yates, age 45, was murdered in February 1975 by having his throat slit in a murder-for-hire scheme. The forensics showed it was by knife, but Gaskins disputed this, saying it was done by karate chop. Yates was in a dispute with his ex-girlfriend Suzanne Kipper Owens, and she and her husband John Owens paid Gaskins $1,500 to murder Yates.

Diane Bellamy Neeley, age 25, was separated from her husband Walter Neeley, who was one of Gaskins closest friends and criminal co-conspirator. On April 10, 1975, Gaskins stabbed to death Dianne Bellamy and shot dead her boyfriend Avery Leroy Howard, aged 34. Among other reasons, Gaskins murdered Dianne Bellamy because she had threatened to report to police that Gaskins was allowing underage teenagers to have sex in his home. Avery Howard was murdered because he asked for money to pay attorneys and cover legal expenses following his arrest for fraud and auto theft. Gaskins worried Avery Howard would tell police about Gaskins's criminal activities.

Kim Gehlken, age 13, was stabbed to death to keep her from telling police Gaskins had moved her from North Charleston without permission, and to keep her from telling police she was being sexually abused by several adult men, including Gaskins.

Dennis Bellamy, aged 27, and John Henry Knight, age 15, were half-brothers, and Dianne Bellamy was their sister. Within minutes of each other, Gaskins shot the two brothers in the back of the head on October 10, 1975. Gaskins had promised to pay Dennis Bellamy for some stolen guns. When confronted by Bellamy at Gaskins's trailer home in Prospect, South Carolina, he responded by offering to return the guns from the woods behind his home. He took Bellamy into the woods to retrieve the guns, but murdered him instead. John Henry Knight was directed to the same area, allegedly to meet his brother, but was also murdered to ensure he could never speak of the crimes.

Rudolph Tyner, aged 23, was on death row in CCI prison for a March 1978 double-murder when he was murdered by Gaskins on September 12, 1982. Tyner was appealing his own death sentence after being convicted for robbing a Murrells Inlet convenience store and killing store owners Bill and Myrtle Moon on March 18, 1978. The Moons' son, Tony Cimo, hired Gaskins for $2,000 to kill Rudolph Tyner because in Cimo's view, the appeals process was taking too long. Tony Cimo asked Gaskins what he needed to kill Tyner, then Gaskins told him to insert some C4 inside the heel of a shoe and mail it to him. This way Gaskins obtained plastic explosives with a blasting cap, a long wire, and a radio speaker to create an imitation intercom speaker that Tyner put to his ear to test. Gaskins then detonated the makeshift bomb by plugging the wire into a prison cell power outlet.

Gaskins was arrested on November 14, 1975, when a criminal associate named Walter Neeley confessed to police that he had knowledge of Gaskins killing Dennis Bellamy, aged 28, and Johnny Knight, aged 15. Neeley confessed to police that Gaskins had confided in him to having killed several people who had been listed as missing people during the previous five years, and had indicated to him where they were buried. On December 4, 1975, Neeley led police to land near Gaskins home in Prospect, where police discovered the bodies of eight of his victims.

Gaskins was tried on one charge 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 Murrells Inlet, South Carolina. Gaskins was hired to commit this murder by Tony Cimo, the son of Tyner's victims. Cimo was initially charged with murder, but pled guilty to lesser charges and was sentenced to 8 years in prison. He was paroled in 1986.

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's 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 to death for the murder of a black man.

While on death row, Gaskins said he 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. These murders have been widely disputed and there has been no evidence to support Gaskins's statements.

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."
