Robert W. "Bob" McLean, a Murfreesboro, Tenn., businessman who donated Bill Monroe's renovated 1923 Gibson F-5 mandolin and Mother Maybelle Carter's 1928 Gibson L-5 guitar to the Country Music Hall of Fame and Museum, was found dead in Shelbyville, Tenn., on Tuesday (Sept. 25) of an apparently self-inflicted gunshot wound. He was 60. Police said a pistol was beside his body when it was discovered Tuesday morning near a church, and a suicide note was also found. At the time of his death, the former stockbroker was involved in multiple lawsuits for allegedly cheating investors out of $20 million and was due to appear in court on Wednesday (Sept. 26) at an involuntary bankruptcy case. An auction of his property will be held to recoup the money he owed investors. At the time of his donations to the Country Music Hall of Fame and Museum in 2004 and 2005, Monroe's mandolin and Carter's guitar had been on the market for $1.125 million and $575,000, respectively. McLean had also donated generous sums to Middle Tennessee State University and Nashville's Schermerhorn Symphony Center.
