Standing just 5 feet 4 inches tall, Donald Henry ‘Pee Wee’ Gaskins Jr. was one of the most prolific and cold-blooded serial predators in American history. Operating across the rural flatlands, swamps, and coastal highways of South Carolina from the 1950s through 1975, Gaskins abducted, tortured, and murdered men, women, and children with absolute ruthlessness. When finally apprehended, he led investigators to shallow graves hidden across rural woodlands. Remarkably, his lethal career did not end behind bars: while serving consecutive life terms in maximum security, Gaskins was hired to assassinate a fellow death row inmate, engineering a devastating C-4 plastic explosive bomb disguised as an intercom. This comprehensive case review explores the forensic body recoveries, prison bomb forensics, and final execution.

The Coastal Plain Disappearances: The Shadow Over Florence County
Throughout the late 1960s and early 1970s, an alarming number of young women, transient hitchhikers, and local acquaintances vanished without a trace across Florence, Sumter, and Williamsburg Counties in South Carolina. Due to the decentralized nature of rural law enforcement and Gaskins’ nomadic lifestyle working as a roofer and mechanic, the disappearances were initially treated as separate missing persons cases.
Gaskins categorized his homicides into two distinct classifications: ‘coastal kills’—opportunistic abductions of strangers, hitchhikers, and motorists whom he tortured and murdered in remote swamp areas—and ‘serious murders’—premeditated killings of friends, business associates, and family members committed for revenge, money, or silencing potential witnesses.
In late 1975, South Carolina Law Enforcement Division (SLED) investigators and Florence County Sheriff’s deputies focused on Gaskins following the disappearance of 28-year-old Doreen Dempsey, her two-year-old daughter, and an associate named Dennis Bellamy. An associate named Walter Neeley broke under police interrogation, confessing that he had accompanied Gaskins to remote logging woods near Prospect, South Carolina, where Gaskins had buried multiple bodies.
Forensic Excavations in the Swamps of Prospect, South Carolina
In December 1975, SLED agents, forensic pathologists, and heavy excavation crews converged on rural pine forests outside Prospect, South Carolina. Guided by Walter Neeley’s directions, forensic teams excavated a series of shallow clandestine graves submerged in marshy soil.
Over several weeks of intensive digging, forensic anthropologists recovered eight skeletal and partially decomposed bodies. Among the recovered victims were Doreen Dempsey (who was eight months pregnant), her toddler daughter, Dennis Bellamy, and several young men who had disappeared years earlier.
Post-mortem skeletal examinations conducted at the Medical University of South Carolina in Charleston revealed evidence of catastrophic blunt force trauma, fractured hyoid bones indicating manual strangulation, and perimortem knife stab incisions into rib cages. Dental chart comparisons matched missing persons files, establishing positive forensic identification for eight victims and providing unassailable physical evidence of premeditated mass murder.
The forensic engineering of the death row bomb remains a landmark case in correctional facility physical security and explosive residue analysis. SLED forensic chemists used gas chromatography-mass spectrometry to detect trace chemical signatures of cyclotrimethylenetrinitramine (RDX), the active military explosive inside C-4 compound, on wire strippers and battery terminals recovered from Gaskins’ personal property. The successful assassination inside a high-security penal institution led to nationwide overhauls in death row security protocols, personal electronic inspection procedures, and physical barrier separation between capital inmates.
The 1976 Trial, Life Sentences, and Maximum Security Confinement
In May 1976, Donald Henry Gaskins stood trial in Florence, South Carolina, for the murder of Dennis Bellamy. The prosecution presented the excavated human remains, forensic dental matches, and the eyewitness testimony of accomplice Walter Neeley.
Recognizing the overwhelming weight of the forensic evidence, Gaskins negotiated a plea agreement to avoid the death penalty, pleading guilty to eight counts of murder. On May 24, 1976, Judge David Morrison sentenced Gaskins to eight consecutive terms of life imprisonment at the Central Correctional Institution (CCI), an archaic maximum-security fortress located in Columbia, South Carolina.
Inside CCI, Gaskins was housed in the maximum-security cell block, where he quickly established a reputation as a cunning, ruthless prison operative with access to contraband, weapons, and illicit internal networks.
The Death Row Intercom Bomb: The Assassination of Rudolph Tyner
In 1982, Gaskins was approached by Tony Cimo, whose elderly parents had been murdered during an armed robbery by death row inmate Rudolph Tyner. Frustrated by endless appellate delays in Tyner’s execution, Cimo offered Gaskins $15,000 to assassinate Tyner inside CCI’s death row unit.
Gaskins accepted the contract and spent months gaining Tyner’s confidence. Gaskins acquired commercial C-4 plastic explosive, copper wiring, and an electric blasting cap through bribed correctional staff. He modified a portable radio intercom unit, concealing several ounces of C-4 inside the battery housing and rigging the circuit to detonate when an external switch was flipped.
On September 12, 1982, Gaskins passed the modified intercom through the cell bars to Tyner, telling him it was a secure communication device that would allow them to speak privately. Gaskins instructed Tyner to hold the speaker cup directly against his ear. Gaskins then walked back to his cell and touched the wire leads to an electrical outlet. The resulting explosion decapitated and fatally mangled Tyner instantly, blowing out the steel cell door and injuring several guards. SLED bomb technicians reconstructed the intercom fragments and traced the wiring directly to Gaskins’ cell.
Capital Conviction for the Prison Bombing and the Electric Chair Execution
The assassination of a death row inmate inside a maximum-security prison using high explosives was unprecedented in American penal history. Gaskins was indicted for capital murder. During the 1983 trial in Richland County, prosecutors presented the physical bomb debris, wire residue found in Gaskins’ possession, and testimony from prison informants.
The jury convicted Gaskins of capital murder, and Judge Walter Bristow sentenced him to death by electrocution. While awaiting execution on death row, Gaskins participated in extensive recorded interviews with author Wilton Earle, claiming responsibility for between 100 and 110 homicides committed across the Southeast over a 25-year period.
On September 6, 1991, at 1:10 a.m., 58-year-old Donald ‘Pee Wee’ Gaskins was strapped into South Carolina’s electric chair at the Broad River Correctional Institution in Columbia. When the switch was thrown, he became the first person in modern South Carolina history to be executed for a murder committed inside the state prison system. His case remains a chilling testament to forensic anthropology in rural body recovery and internal prison security forensics.

Frequently Asked Questions: Forensic & Legal Review
How did Pee Wee Gaskins execute a fellow inmate on death row?
Gaskins accepted a $15,000 murder-for-hire contract from the family of Rudolph Tyner’s victims. He smuggled C-4 plastic explosives and a blasting cap into the prison, built a bomb inside a portable intercom radio, gave it to Tyner under the pretense of a secure communications line, and detonated it when Tyner held the speaker to his ear.
How many victims did Pee Wee Gaskins officially kill?
Gaskins was officially convicted of nine murders (eight rural victims excavated in 1975 and Rudolph Tyner in 1982) and confessed to another murder in 1978. In total, he claimed responsibility for over 100 to 110 homicides in his taped memoirs, though forensic investigators verified approximately 15 to 20.
What forensic methods were used to find Gaskins’ burial sites?
SLED agents and forensic anthropologists used information from informant Walter Neeley, soil disturbance probing, heavy trenching equipment, and forensic dental comparisons to recover and identify eight bodies buried in swampy woodlands near Prospect, South Carolina.
