The Last Mile by David Baldacci

Melvin Mars was a shoo in for the NFL until he wasn't.   Convicted of the murder of his parents, Melvin is on death row in Texas, the state that tries to out do all other states for capital punishment.   Amos Decker suffers from synesthesia and has eidetic memory.  His memories as a football player being run over by Melvin Mars are one facet that draws him to invest in an investigation of Melvin Mars.  

Agent Bogart has created a mixed task force of talented civilians and agents to tackle cold cases.   Amos Decker's attributes and his former career as a cop guarantees him a place on the team.   A psychologist, a journalist and another FBI  agent fill out the team.   Amos focuses them on Melvin and the resultant action leads the entire team into danger and intrigue.  

Baldacci is a master story teller who never seems to run short on excitement of plot.

I highly recommend it.
