Grammy Award-winning Christian rapper TobyMac and his family are mourning the loss of his oldest son, Truett Foster McKeehan, according to news reports.

McKeehan, 21, was found dead at his Nashville home Wednesday, the Davidson County Medical Examiner's Office confirmed to NBC News.

“Truett Foster Mckeehan had joy that took the room when he entered. He was a magnetic son and brother and friend. If you met him, you knew him, you remembered him,” TobyMac wrote in an Instagram post about his son’s death.

“He had an untamable grand personality and dreams to match,” he wrote.

The aspiring musician, who released music under several names, including Truett Foster and truDog, was found by a friend, WZTV reported.

There were no signs of foul play, and police told the news station McKeehan did not die by suicide.

An autopsy is scheduled to determine a cause of death.

TobyMac, whose real name is Toby McKeehan, canceled his concert tour in Canada to return to Nashville to be with family, according to CBN News.

“My last moment with Truett in person was at his first show this past Thursday at the Factory in Franklin, Tennessee. I had to leave the next morning very early to fly and start our Canadian tour. As I stood in the audience and watched my son bring joy to a room, I was as proud as a “pop” (as tru called me) could be,” TobyMac said.

Truett McKeehan was the oldest of TobyMac’s five children.

The rapper said last year that the song "Scars" off his latest album, "Elements," was written for his son, the Digital Journal reported.

The song’s lyrics include the lines, “Life ain’t got no sequel, we all broken people. The only road to found is lost.
