Jamell Maurice Demons (born May 1, 1999), known professionally as YNW Melly (initialism for Young Nigga World Melly), is an American rapper and singer. He rose to fame in 2018 following the release of his single "Murder on My Mind," a trap song that explores homicidal ideation. As his mainstream breakthrough, its release garnered him further attention after he was charged with the double-murder of two fellow rappers in the "YNW" collective the following year, resulting in an ongoing legal battle and incarceration. Prior, "Murder on My Mind" peaked at number 14 on the Billboard Hot 100 and led him to sign with 300 Entertainment to issue the song as a single for his debut commercial mixtape I Am You (2018), which was met with positive critical reception along with its follow-up, We All Shine (2019).

Both mixtapes entered the Billboard 200 chart and received gold certifications by the Recording Industry Association of America (RIAA); We All Shine contained the double platinum-certified song "Mixed Personalities" (featuring Kanye West), and his incarceration began shortly after its release. His first two studio albums, Melly vs. Melvin (2019) Just a Matter of Slime (2021), both maintained his commercial success despite mixed critical response. The former was supported by two Billboard Hot 100-top 40 singles—"223's" (featuring 9lokkNine) and "Suicidal" (remixed featuring Juice Wrld)—and peaked at number eight on the Billboard 200, while the latter peaked at number 11. His third studio album, Young New Wave (2024) was generally panned by critics, and failed to chart.

In February 2019, he was arrested and charged with two counts of premeditated murder for which he faces life without the possibility of parole or the death penalty if convicted. He is also a suspect in the 2017 murder of a sheriff's deputy in Gifford. In March 2019, Demons pleaded not guilty to the double-murder charges. His first trial ended in a hung jury, and as of January 2024, his retrial is paused and awaiting adjudication for the inclusion of digital evidence. As of July 2024 his trial has been pushed back until September 2025.

Jamell Demons was born on May 1, 1999, and grew up in Gifford, Florida. He was raised by his single mother, Jamie Demons-King, and does not know who his father is. Another rapper, Donte "Tha Gift" Taylor, claims to be YNW Melly's father. His mother was 14 years old when she became pregnant with him, giving birth to him in ninth grade. Later moving to a poorer part of Gifford, she struggled to pay for housing and basic necessities.

After a year of not releasing music and still fighting his pending murder case, on March 5, 2021, Demons recruited fellow Florida artist Kodak Black for the release of "Thugged Out". This was followed up with other notable singles such as "Pieces" featuring Queen Naija and "Bestfriend 4L" featuring Lil Tjay. The singles leading up to Demons' sophomore studio album, Just a Matter of Slime, like Melly vs. Melvin were released while incarcerated and were put together with pre-recorded vocals prior to his incarceration.

YNW Melly has been noted for his melodic vocals and his "mix of bright harmonies slathered in grit and soulful love-sick ballads".

Demons was arrested on October 19, 2015, on three counts of aggravated assault with a deadly weapon and one count of discharging a firearm in public, after firing shots at three people near Vero Beach High School. Demons spent a year in jail before being released on probation.

In 2017, Demons was arrested for violating probation and spent several months in jail before being released in March 2018.

Demons was arrested on June 30, 2018, in Fort Myers, Florida for possession of marijuana, possession of weapon or ammunition by a convicted felon, and drug paraphernalia.

Demons was again arrested on January 3, 2019, in Fort Myers for possession of marijuana.

On February 13, 2019, Demons was charged with two counts of premeditated murder in connection with the October 2018 shooting deaths in Fort Lauderdale, Florida of two YNW associates described as his close friends, rappers YNW Sakchaser and YNW Juvy. Authorities purport that Demons conspired with fellow YNW rapper Cortlen Malik Henry (YNW Bortlen) to stage the double-murder of Anthony D'Andre Williams (YNW Sakchaser) and Christopher Thomas Jr. (YNW Juvy) and make it appear as if they were fatally injured in a drive-by shooting. Demons turned himself in on February 13, 2019. He announced on his Instagram:

"No I did not get locked up in Washington, but I am turning myself in today... a couple months ago I lost my two brothers by violence and now the system want to find justice.. unfortunately a lot of rumors and lies are being said but no worries god is with me and my brother @ynw.bortlen and we want y'all to remember it's a ynw Family I love you"

On February 22, 2019, Complex reported that Demons and Henry were suspects in the fatal 2017 shooting of off-duty Indian River County Sheriff's Department deputy Garry Chambliss in Gifford.

On November 30, 2021, Demons' double murder trial was set for March 7, 2022. The trial was later delayed and reset for May 23, 2022. Delayed again, the trial was pushed back until June 6, 2022.

After the trial did not proceed, Demons' defense team decided to submit a speedy trial request on May 26, 2022. The trial would have to commence in the next 175 days.

On July 6, 2022, a decision was announced that Demons would no longer face capital punishment if convicted. However, on November 9, 2022, the decision was overruled by an appellate judge, once again making Demons eligible for capital punishment if sentenced. Following the eligibility, Demons' team attempted to get this thrown out with an appeal to the Supreme Court of Florida; however, this attempt was unsuccessful.

Jury selection for Demons' double murder case had begun on April 11, 2023. Melly's trial began on June 12, 2023.

According to the prosecutors, forensic and video evidence point to Demons as the killer. Surveillance footage showed him taking the seat inside the car from which experts determined the shots were fired. Demons alleged the victims died as a result of a drive-by, even though prosecution evidence showed the fatal shots that killed the pair had come from inside the car. Demons and Henry were accused of parking, exiting the car, then staging the killings by shooting back into the vehicle, after which Henry solely drove the victims to Memorial Hospital in Miramar, where they were pronounced deceased. The jury deliberated for fourteen hours over three days but were unable to reach a unanimous verdict, even after the judge gave them an Allen charge, a direction that urged them to try to come to unanimous conclusion. A mistrial was declared July 22, 2023 as the jury could not come to a unanimous decision. Demons remains in custody awaiting his retrial. On September 22, 2023 Broward Circuit Judge John Murphy declined to grant the rapper bond as he awaits his a new trial set for October 2, 2023.

In January 2024 the trial was put on hold indefinitely after a judge's ruling to suppress a promotional video about Melly's life from evidence prompted prosecutors to file an appeal.

On April 2, 2020, Demons (via management) told fans on Twitter that he tested positive for COVID-19. He was in the process of trying to get an early release from prison due to health concerns, as 6ix9ine was released from prison due to asthma and bronchitis. On April 14, his motion was denied.

Demons claims to suffer from split personality disorder, in which he has a second personality called Melvin. Demons claims Melvin is the violent side of his personality and Melly is the happy and loving side.
