What does the case include?
“Jonestown” is often used as shorthand for several connected events in Guyana on 18 November 1978. For accuracy, this file separates them: the attack on Ryan's delegation at the Port Kaituma airstrip; the deaths at the Peoples Temple settlement known as Jonestown; and four deaths at the Temple's Georgetown house.
Contemporaneous State Department records and later National Archives summaries count 918 deaths in all. Of these, 909 were at Jonestown, five at Port Kaituma and four in Georgetown. The different locations and mechanisms matter because the later U.S. prosecution concerned the airstrip attack, not a single criminal indictment encompassing all 918 deaths.
Why did Representative Leo Ryan travel to Guyana?
Representative Leo J. Ryan of California traveled to Guyana after former Temple members and relatives alleged abuse and that residents were being held against their will. His party included congressional staff, journalists and concerned relatives. The group reached Jonestown on 17 November. During the visit, some residents asked to leave with Ryan's party.
On 18 November, Ryan and the departing group went to the Port Kaituma airstrip to board aircraft. The FBI's case history states that Peoples Temple members ambushed the party there.
The Port Kaituma attack
Gunmen arrived at the airstrip in a tractor and trailer and opened fire on the group near the aircraft. Ryan, NBC cameraman Bob Brown, NBC correspondent Don Harris, San Francisco Examiner photographer Greg Robinson and Peoples Temple member Patricia Parks were killed. Other members of the party were wounded.
Larry Layton had posed as a defector and boarded one of the planes. Federal prosecutors later charged him with conspiracy, aiding and abetting Ryan's murder, and related attempted-murder counts. The distinction is important: the five airstrip deaths formed the core of the criminal case that reached a final U.S. judgment.
The deaths at Jonestown and Georgetown
After the airstrip attack, Jones gathered the Jonestown community and ordered a cyanide-laced drink prepared and consumed. The FBI records 909 dead at the settlement, including more than 200 children. Four Temple members also died in Georgetown.
The FBI calls the event a mass murder and suicide. That wording is essential. Some adults participated in the poisoning, but children could not consent, and survivor accounts and physical evidence describe force or coercion. This archive therefore does not reduce the event to “mass suicide” or imply that every person died voluntarily.
Victim-aware terminology: The 909 people at Jonestown were not a single voluntary category. Children and coerced residents are described as victims. The archive avoids graphic detail and does not reproduce the settlement's recorded final moments.
The FBI's RYMUR investigation
The FBI opened the investigation code-named RYMUR, short for Ryan Murder, after Guyanese authorities requested assistance. Agents collected evidence from Jonestown and examined extensive Peoples Temple records. The FBI Vault now preserves thousands of pages from that inquiry.
The investigation established the organizational context and helped support the federal case against Layton. Most of the central Temple leadership, including Jones, died in Guyana. That fact sharply limited the number of defendants who could be brought to trial and explains why there was no comprehensive prosecution of every death.
The Larry Layton prosecution
Layton was indicted on four federal counts arising from the Port Kaituma attack. An earlier trial ended without a verdict, but his retrial began on 18 September 1986. On 1 December 1986, the jury found him guilty on all four counts.
On 3 March 1987, the court imposed a life sentence on the count involving Ryan's murder and fifteen-year terms on the other counts. In 1988, the U.S. Court of Appeals for the Ninth Circuit affirmed the convictions in United States v. Layton, 855 F.2d 1388.
Layton's conviction is the clearest final judicial outcome connected to the events. It established his criminal responsibility for the airstrip conspiracy and attack. It did not amount to a verdict against every person involved at Jonestown, nor did it adjudicate all 909 settlement deaths.
Why the archive classifies the case as solved
Crime by Region uses “solved” here in a qualified sense. Official U.S. records identify the responsible organization and leadership, the major sequence is extensively documented, and the Port Kaituma prosecution produced four affirmed convictions. This is not a case in which the perpetrators or basic event are unknown.
At the same time, legal closure was incomplete. Jones and many participants died before any trial; no criminal court issued a comprehensive judgment for the Jonestown deaths; and individual responsibility for every act was never litigated. The accurate label is therefore solved / responsibility established—Port Kaituma conviction affirmed; broader Jonestown deaths not comprehensively adjudicated.

What the verdict did not decide
- Every Jonestown death: the Layton prosecution concerned Port Kaituma; it was not a trial of all 909 settlement deaths.
- Every individual act: many potential defendants died, and responsibility could not be allocated in court across the entire community.
- Voluntariness for every adult: the record includes coercion, and the archive does not infer consent person by person.
- A single legal label for all locations: murder, attempted murder, suicide and coercion appear in a connected but legally uneven event.

Frequently asked questions
What happened at Jonestown on 18 November 1978?
After a Peoples Temple gun team attacked Representative Leo Ryan's party at Port Kaituma, Jim Jones ordered a cyanide poisoning at Jonestown. Official records count 909 deaths there, including more than 200 children.
How many people died in Guyana?
The U.S. State Department and National Archives record 918 deaths in all: 909 at Jonestown, five at Port Kaituma and four in Georgetown.
Why is the event called mass murder-suicide?
The FBI uses that description because some adults participated, while children and other residents were killed or coerced. Calling all 909 deaths voluntary would misstate the evidence.
Who was convicted after the Port Kaituma attack?
Larry Layton was convicted in 1986 on four federal counts connected to the airstrip attack. He received a life sentence on one count and concurrent fifteen-year terms on the others; the Ninth Circuit affirmed the convictions in 1988.
Does solved mean every death was tried in court?
No. The archive's solved classification reflects established responsibility and Layton's final federal convictions. Jim Jones and many participants died in Guyana, so no comprehensive criminal trial adjudicated all 909 Jonestown deaths.
Who were the five people killed at Port Kaituma?
Representative Leo Ryan, NBC cameraman Bob Brown, NBC correspondent Don Harris, San Francisco Examiner photographer Greg Robinson and Peoples Temple member Patricia Parks were killed at the airstrip.
