Do police have the right to search a coffin thats being transfered in a Hearse?

if the police justifiably believe that there is contraband (stolen goods, illegal weapons, drugs, etc) in the coffin, and they have a COURT ORDERED search warrant, YES, they may legally stop the hearse and search the coffin. As messed up as you say this is, CROOKS know the law also and are very creative in where they hide their loot.
