Groves then tweeted that his sister's death was the result of "natural causes," pending a final coroners report. Both foul play and self-harm were ruled out by the coroner, Cady's representative told PEOPLE.
Groves also told Cady's fans that the "This Little Girl" singer had previously been struggling with her health. "She had some medical problems last fall and our best guess at this point until further testing is complete is that they had resurfaced," Groves wrote. "Please respect her name and family before sharing information that did not come directly from here."
He also shared that the Emporia, Kansas native was excited about releasing new music before her death. "[Cady] was really looking forward to the next few months and release of her new album," Groves said. "Our latest in depth conversation (since most were witty banter) was her sending me songs to critique and give feedback on."
