Lloyd was a talented and popular singer, a member of the country and pop music scenes of the 1960s and 1970s.
He died Thursday, according to his wife.
He was 52.
He had been hospitalized since July 30 with pneumonia.
He has been in a medically induced coma since he fell and hit his head in a shower, the Los Angeles County coroner’s office said.
It is not clear what caused Lloyd’s injuries, but he was found unresponsive in the shower.
His death was the second of his career, and his death is one of the biggest mysteries in the country.
“We’re still trying to piece together what happened, and we’ll never know if he had a stroke or a heart attack,” said his daughter, Kristin Lloyd.
The cause of death has not been determined, the coroner’s statement said.
“This is a sad and tragic loss for all of us who love him.
We will forever miss his energy, humor and his spirit,” said her husband, Dave Lloyd.
In the early 1980s, he was one of country music’s most popular singers.
His hits included “I’ll Make a Living for My Country,” “Let the Good Times Roll” and “The Big Sky.”
He sang in “The Great American Songbook” and wrote a song for President Ronald Reagan.
He made his country and gospel debut in 1988 with the release of “My Sweet Country.”
Lloyd’s wife, Kristina, told the Associated Press she and their children, who live in Georgia, were saddened to learn his death was related to the stroke.
“It’s very sad,” Kristin said.
Her husband and daughters, both singers, were friends and frequent performers at his shows.
Lloyd was one half of the folk group The Lonesome George and had the distinctive voice of a country singer.
He sang and performed with the group and with other country stars such as Jimmie Rodgers and Hank Williams Jr. Lloyd also was a vocalist for his band The Lonestar Brothers and was inducted into the Country Music Hall of Fame in 1990.
The Associated Press was first to report the news of Lloyd’s death.
