In MEMORY of John R. Bell

The family of John R. Bell apparently MEMORIALIZED him as

 the victim of a murder when he and his son, John A. Bell,

 were killed in a shootout on the streets of Cahawba in 1856.

 The three other  men involved were exonerated in court,

 but the Bell Family declared via the inscription on his tombstone:

 "No murderer hath eternal life abiding in him."
