McKeehan overdosed on fentanyl and amphetamines on Oct. 23, 2019, in a Nashville home.

The 21-year-old was an aspiring rapper who released music under the names Truett Foster, truDog, TRU and Shiloh.

TobyMac recently released a song called "21 Years" in honor of his late son. In it, TobyMac wrestles with the pain of losing his son, whose death was unexpected.

"'21 years' is a song I wrote about the recent passing of my firstborn son, Truett Foster McKeehan," TobyMac says about this personal song. "I loved him with all my heart. Until something in life hits you this hard, you never know how you will handle it. I am thankful that I have been surrounded by love, starting with God's and extending to community near and far that have walked with us and carried us every day. Writing this song felt like an honest confession of the questions, pain, anger, doubt, mercy and promise that describes the journey I'm probably only beginning. The rest is yet to come. One thing I know is that I am not alone. God didn't promise us a life of no pain or even tragic death, but He did promise He would never leave us or forsake us. And I'm holding dearly to that promise for my son as well as myself."

McKeehan's "heart was warm to the things of his King," TobyMac says.

Two months ago, TobyMac and his wife, Amanda Levy McKeehan, created the Truett Foster Foundation in honor of their son. The charity provides money for kids pursuing an education in music. According to the organization's website, 100% of donations will go toward funding scholarships so that vulnerable youth "may realize their God-given potential to change the lives of others."
