Investigators for Scotland Yard have told PEOPLE that they are dealing with a “sudden death” in the Westminster district of London. “Officers were called at 9:05 a.m. on Monday Jan. 15 to a hotel in Park Lane. A woman in her mid-40s was pronounced dead at the scene. At this early stage the death is being treated as unexplained and enquiries continue.”

Soon after the news was announced, fans and fellow musicians flocked to social media to honor the singer, who gave voice to alt-rock classics including “Linger,” “Zombie” and “Dreams.” James Corden shared a sweet story about meeting O’Riordan during his youth.

Irish artists Hozier and Kodaline also paid their respects.

“My first time hearing Dolores O’Riordan’s voice was unforgettable,” said Hozier. “It threw into question what a voice could sound like in that context of Rock. I’d never heard somebody use their instrument in that way. Shocked and saddened to hear of her passing, thoughts are with her family.”

Last July, the Cranberries were forced to cancel their North American and European tours, citing O’Riordan’s health problems as the cause. “Unfortunately Dolores O’Riordan’s recovery from her ongoing back problem which forced the cancellation of most of the band’s European tour this Summer has not been going as well as expected to such extent that her Doctors have now instructed her to cancel her upcoming almost sold out tour of North America with the band,” read a statement posted to the band’s Facebook page at the time.

Just a little more than three weeks before her sudden death, O’Riordan assured her fans she was now “feeling good” following the tour issues.

“Hi All, Dolores here. Feeling good!” she wrote on the band’s Facebook account. “I did my first bit of gigging in months at the weekend, performed a few songs at the Billboard annual staff holiday party in New York with the house band. Really enjoyed it! Happy Christmas to all our fans!!”

O’Riordan is survived by her three children, 20-year-old son Taylor, 16-year-old daughter Molly and 12-year-old daughter Dakota.

“The best time in my life was the years spent at home with my family,” she told the Irish News in May 2017. “I love being a mum. My kids don’t see me as a famous person, or have any kind of expectation; I’m just their mum.”
