American gospel singer and songwriter Joyce Dottie Rambo has died age 74, due to an unfortunate accident Sunday in Missouri, in which her tour bus ran off the highway and hit an embankment.

Dottie Rambo died early Sunday, May 11, when her tour bus was wrecked about two miles east of Mount Vernon on Interstate 44, the Missouri Highway Patrol said. Seven other people on the bus were injured and required hospitalization. The injuries ranged from moderate to severe, the patrol told the Associated Press.

It remains unclear whether the crash was related to the severe storms and tornadoes that hit the region on Saturday. The National Weather Service reported additional storms in the area later in the night.

Rambo was on her way to a Mother’s Day performance in North Richland Hills, Texas when the crash happened.

“She was a giant in the gospel music industry,” said Beckie Simmons, Rambo’s agent. “Dolly Parton recorded some of her songs.”

Dolly Parton in turn paid tribute to the singer, calling her “a dear friend, a fellow singer, songwriter and entertainer, and as of late my duet singing partner.”

“I know Dottie is in heaven in the arms of God right now, but our earth angel will surely be missed,” Parton said in a statement. “Dottie was.” The singer also sent condolences to “everyone involved in this terrible tragedy.”

The singer was inducted into the Nashville Songwriters Hall of Fame last year and the Kentucky Music Hall of Fame in 2006.

The Nashville, Tenn.-native has had more than 2,500 published songs, including gospel classics such as “He Looked Beyond My Fault and Saw My Need” and the 1982 Gospel Music Association Song of the Year, “We Shall Behold Him.”
