His death was announced on Facebook by his brother Myles Reed, Jr. on February 26, 2014:

It is with a very heavy heart that I share this information. My brother, Frank K. Reed passed away this morning. I don't have the details, and am having a hard time believing that it is true. Many of you know that he was a member of the Chi-lites for the past almost 30 years. One thing I do know, is that he lived his dream. Rest in Peace, Frank! This is very hard for us. I will forward more information as I receive it.
 
Our condolences to the family of Frank Reed.
