Rodney King was under the influence of cocaine, PCP, marijuana and alcohol at the time of death, according to the death report released Thursday, TMZ reports.

The cause of death is listed as accidental drowning -- but the drugs were contributing factors.

He was in a state of "drug- and alcohol-induced delirium at the time" and "either fell or jumped into the swimming pool," according to the San Bernardino County coroner's report, the Los Angeles Times reports.

The drugs, combined with a heart condition, led to a cardiac arrhythmia, and King was “thus incapacitated, was unable to save himself and drowned," according to the report. King's blood-alcohol level was 0.06.

"There is nothing in the history or autopsy examination to suggest suicide or homicide," the report states, the San Bernardino County Sun reports.

The PCP found in King's blood is noteworthy because the Los Angeles police officers involved in the 1991 beating said they believed he was on PCP, which can make its users impervious to pain. However, tests at the time showed no trace of the drug.

King, 47, died in June after he was found by his fiancee, Cynthia Kelley, at the bottom of the backyard pool at his Rialto home.

Kelly said that she awoke to King screaming in the backyard at about 5 a.m. She found him naked, banging on glass and, when she went to get her phone, she heard a big splash.

When police arrived, they also found a pitchfork, a hoe and a vacuum pool sweeper in the pool, according to TMZ. Kelley told the officers that she used the tools to try to fish her fiancé out of the water instead of jumping in because she is not a good swimmer and was afraid to enter the water.

King had struggled with addiction for years after the beating, even appearing on "Celebrity Rehab with Dr. Drew." In his recently-published memoir, “The Riot Within: My Journey from Rebellion to Redemption,” he wrote that he still drank and used drugs occasionally but that, with Kelley, who had been a juror in a civil suit he brought against the City of LA, he was on his way to recovery.

On the 20th anniversary of the beating in March of this year, King told reporters that he was happy.

King became famous in 1991, when a witness videotaped an altercation between King and Los Angeles police. The video (watch below) shows officers brutally beating King and was subsequently broadcast on news outlets around the world.

After officers involved in the beating were acquitted, the 1992 Los Angeles riots began. The police lost control of the city, and there were 53 deaths, 3,600 fires, 10,000 destroyed businesses and an estimated $1-billion-plus worth of damage.

Responding to the racial tensions that fueled the riots, King famously pleaded at the time for peace, saying "Can we all get along?"

  • The Verdict: 'It Was Never Even Close'

    On April 29, 1992, the jury acquitted all four officers of assault and acquitted three of the four of using excessive force. Some said the fact that the jury was made up on ten whites, one Latino and one Asian gave an unfair advantage to the white defendants. "Everyone says, 'The video tape! The video tape!' These officers have a job to do. And in doing that job, they have to be given a certain amount of... reasonable force," one juror told ABC. "They didn't know what they had to take. A man that's over 230 pounds, and you put him on the ground, and four officers go in to put hand cuffs on him. And he throws those officers off?" Anther juror said about the violent reaction to the verdict, "I can't help but feel somewhat responsible." And yet, he said, if he had to do it again, he would vote the same way.

  • 'You're On Your Own Here'

    "You're on your own here," one cop told this videographer. Another man said, "What's goin' on is.. They're doing it in the wrong area.

  • Rodney King: 'Can We All Get Along?'

    This is a clip of the first time Rodney King spoke to the media after the riots began.

Here's the transcript of the speech: <blockquote>I just want to say, you know, can we, can we all get along? Can we, can we get along? Can we stop making it horrible for the older people and the kids? And... I mean we've got enough smog in Los Angeles let alone to deal with setting these fires and things. It's just not right. It's not right. And it's not going to change anything. We'll get our justice. They've won the battle, but they haven't won the war. We'll get our day in court and that's all we want. And, just, uh, I love -- I'm neutral, I love every -- I love people of color. I'm not like they're making me out to be. We've got to quit. We've got to quit. Afterall, I mean, I could understand the first, the first upset for the first two hours after the verdict, but to go on, to keep going on like this and to see the security guard shot on the ground. It's just not right. It's just not right. Because those people will never go home to their families again. And uh, I mean please, we can, we can get along here. We all can get along. We just gotta, we gotta. I mean, we're all stuck here for a while. Let's, you know, let's try to work it out. Let's try to beat it, you know. Let's try and work it out.</blockquote>
