Grim Sleeper

On March 28, 2020, Franklin was found unresponsive in his cell and was pronounced dead at 7:43 p.m. His cause of death is pending the results of an autopsy; however, there were no signs of trauma.

In July 2010, Franklin was arrested as a suspect, and, after many delays, his trial began in February 2016. On May 5, 2016, the jury convicted him of killing nine women and one teenage girl. On June 6, 2016, the jury recommended the death penalty, and on August 10, 2016, the Los Angeles Superior Court sentenced him to death for each of the ten victims named in the verdict. On March 28, 2020, he was found unresponsive in his cell at San Quentin State Prison and pronounced dead.

Franklin was charged with ten murders and one attempted murder. He was held without bail until he received his death sentence. He is not charged in the death of an eleventh suspected victim, a black man, a crime for which DNA evidence was not found. On May 5, 2016, after nearly three months of trial and a day and a half of jury deliberation, Franklin was convicted of ten counts of murder and one count of attempted murder. On June 6, 2016, a Los Angeles County jury sentenced Franklin to death.

After a lengthy pretrial discovery and several delays, the trial opened on February 16, 2016. Closing arguments began May 2, 2016 and the jury began deliberating May 4, 2016. The jury convicted Franklin on all counts on May 5, 2016. On June 6, 2016, the jury rendered a verdict of death. On August 10 the Superior Court sentenced Franklin on each count, naming the individual victims.

During the gang rape photographs were taken by one of the rapists – as was the case with the women Lonnie Franklin later raped and murdered.

On November 3, 2011, Reuters reported that the police were considering Franklin as a suspect in six more slayings of additional female victims. The police were investigating two of the six as potential victims killed during a 14-year lapse between an initial spate of Grim Sleeper murders that ended in 1988 and several more that began in 2002. Of the remaining four victims, two bodies were discovered in the 1980s and two were reported missing in 2005 but the remains of the other two were never found, police said. Detectives said they linked Franklin to the six additional killings after reviewing hundreds of old case files and seeking the public's help in identifying a collection of 180 photographs of women and girls that were found in his possession.

On July 7, 2010, the Los Angeles Times reported that an arrest had been made. Los Angeles County District Attorney Steve Cooley identified the suspect as 57-year-old Lonnie David Franklin Jr., a mechanic who worked between 1981 and 1988 for the City of Los Angeles in the sanitation department and briefly for the LAPD. Franklin was identified for arrest, at least in part, on familial DNA analysis.

On December 16, 2010, the LAPD released 180 photos of women, found in Franklin's home after unsuccessful attempts to identify the individuals, possibly additional victims. "These people are not suspects, we don't even know if they are victims, but we do know this: Lonnie Franklin's reign of terror in the city of Los Angeles, which spanned well over two decades, culminating with almost a dozen murder victims, certainly needs to be investigated further," said Police Chief Charlie Beck.

On July 7, 2010, Lonnie David Franklin Jr., 57, was arrested. The Los Angeles County District Attorney's Office charged him with ten counts of murder, one count of attempted murder, and special circumstance allegations of multiple murders in the case.

In early September 2008, Los Angeles officials announced that they were offering a $500,000 reward to help catch the killer. On November 1, the case was featured on the Fox program America's Most Wanted. On February 25, 2009, Bratton addressed the press for the first time regarding the case, at which time the police formally gave the killer the "Grim Sleeper" nickname chosen by LA Weekly. Bratton also released a 9-1-1 call from the 1980s in which a man reported seeing a body being dumped by Franklin, giving a detailed description and license plate number of a van connected with the now-closed Cosmopolitan Church.

In March 2009, Pelisek conducted an extensive interview with Enietra Washington, the sole survivor of Franklin's attacks. Washington described him as "a black man in his early 30s [⁠ ⁠.⁠ ⁠.⁠ ⁠.⁠ ⁠] He looked neat. Tidy. Kind of geeky. He wore a black polo shirt tucked into khaki trousers." She also described the interior and exterior of his vehicle.

Police had found no exact match between DNA found at the crime scenes and any of the profiles in California's DNA profile database, so they searched the database for stored profiles that demonstrated sufficient similarity to allow police to infer a familial relationship. They found similar DNA belonging to Franklin's son, Christopher, who had been convicted of a felony weapons charge in 2008. Christopher was too young to have committed the murders, but the familial DNA match led investigators to look at his father, Lonnie, as the likely perpetrator. According to Cooley, detectives then used a piece of discarded pizza with Franklin's DNA to make the link.

In May 2007, the slaying of Janecia Peters, 25, was linked through DNA analysis to at least eleven unsolved murders in Los Angeles, the first of which occurred in 1985. That same year, in secrecy, the LAPD formed the "800 Task Force," composed of six detectives and overseen by the Robbery-Homicide Unit. After a four-month investigation, LA Weekly investigative reporter Christine Pelisek broke the news of the task force's existence, the link between Peters' killing and the earlier murders, and the silence of Mayor Antonio Villaraigosa and Police Chief William J. Bratton regarding the killer's existence. Villaraigosa and Bratton neither issued a press release nor warned the community. In some cases, LA Weekly was the first to inform the families that their daughters had long been confirmed as victims of a serial killer.

Law enforcement missed an opportunity to catch Franklin because his DNA was not previously collected. In 2003, Franklin was convicted of a felony and was serving three years of supervised probation. In 2004, voters passed Proposition 69, which requires that DNA must be collected from all felons and everyone arrested on some specified charges. It also requires the expansion of the DNA database. Authorities collected and sorted through thousands of DNA samples. While he was on probation, Franklin's DNA was supposed to be entered in the system but was not as probation officers did not collect samples from people who were on unsupervised probation between November 2004 and August 2005. The probation department did not have the resources to collect samples until August 2005.

In 1989, he was also convicted of two charges of theft, one charge of misdemeanor assault, and one charge of battery. He served time for one of the theft charges.

One of Franklin's suspected victims, although there is no DNA evidence to support the accusation. Police said that the male victim, Thomas Steele, possibly was a friend of another victim or had discovered the killer's identity. Enietra "Margette" was told to use her middle name as her last name for her protection, but has since come forward as Enietra Margette Washington. Attacked on November 20, 1988, she is the only known survivor.

In the 1980s, the LAPD marked the deaths of several women in South Los Angeles with the identification “NHI”, meaning "no humans involved", which was used for cases involving chronic drug users and prostitutes. Margaret Prescod formed the "Black Women Count" movement with community members to pressure the LAPD into acknowledging the deaths as serial killings and forming a task force in response. The coalition launched a media campaign and set a monetary reward aiming to capture the killer. The joint LAPD-Los Angeles County Sheriff's Department investigation determined that the crimes were committed by a single person labeled the "Southside Slayer". Their results were announced to the public on September 23, 1985.

The known killings began in 1985 in South Los Angeles. The "Grim Sleeper" apparently took a 14-year hiatus after his last known crime in 1988 and the murders then resumed in 2002 (leading to the epithet by which he is known), but this history may be only an accident of the evidence collected. The last confirmed slaying was in January 2007. All of his victims were found outdoors, often in alleys a short distance from downtown Los Angeles.

Lonnie David Franklin, Jr. (August 30, 1952 – March 28, 2020), better known by the nickname Grim Sleeper, was an American serial killer who was responsible for at least ten murders and one attempted murder in Los Angeles, California. He was also convicted for rape and sexual violence. Franklin earned his nickname when he appeared to have taken a 14-year break from his crimes, from 1988 to 2002.

Lonnie David Franklin Jr. was born on August 30, 1952. He grew up in South Central Los Angeles, California. He married and had two children. He was given a dishonorable discharge from the United States Army on July 24, 1975, after having been released from prison for his conviction of gang-raping a 17-year-old girl in Stuttgart, West Germany.
