Tom Petty died on Monday night, but inaccurate news of his death made its way around the internet much earlier in the day.
According to Tony Dimitriades, longtime manager of Tom Petty & The Heartbreakers, the legendary rocker "died peacefully at 8:40 pm PT surrounded by family, his bandmates and friends" after suffering cardiac arrest.
That was hours after some media outlets had already reported on his death -- a mistake that prompted one of Petty's daughters to vent her anger about it on social media.
An Instagram account believed to belong to AnnaKim Violet Petty featured a post with a blistering message to Rolling Stone magazine, which reported Petty had died on Monday afternoon.
"My dad is not dead yet but your f***ing magazine is," the post read.
"How dare you report that my father has died just to get press because your articles and photos are so dated," Petty added with a picture of her father on the cover of a 1980 issue of Rolling Stone. "This is my father not a celebrity. An artist and human being."
Petty's daughter and Rolling Stone did not respond to CNNMoney's request for comment on this story.
She started posting photos of her father on Sunday and continued throughout Monday. In one post that included the song lyrics to "All Right For Now," Petty wrote "thank you for all the love."
The stream of heartfelt tributes was interrupted only by her remarks about Rolling Stone.
TMZ, citing law enforcement sources, was first to post a story Petty had been hospitalized.
"We're told after Petty got to the hospital he had no brain activity and a decision was made to pull life support," TMZ reported at 3:30 pm ET on Monday.
At 4 p.m. ET, CBS News, citing Los Angeles Police, tweeted that Petty had died and included a link to an obituary.
Other media outlets, including E! News, picked up the story, which led to an outpouring of grief from Petty fans and celebrities, including Bob, Dylan, Sheryl Crow, John Mayer and Ed Helms.
Variety published a collection of some of the tweets mourning Petty.
"The singer is not expected to live through the day, but he's still clinging to life," TMZ reported at 4:35 p.m. ET.
News outlets began correcting their reporting. The Los Angeles Police Department tweeted an apology.
"The LAPD has no information about the passing of singer Tom Petty. Initial information was inadvertently provided to some media sources," the tweets read. "However, the LAPD has no investigative role in this matter. We apologize for any inconvenience in this reporting."
CBS News retweeted the LAPD post and added, "The LAPD says it cannot confirm earlier reports of singer Tom Petty's death. TMZ reports that the singer is still clinging to life."
The confusion both stumped and angered some fans.
CBS released a statement on Monday about the snafu.
"CBS News reported information obtained officially from the LAPD about Tom Petty," the statement read. "The LAPD later said it was not in a position to confirm information about the singer."
