The Bodyguard who is guarding the Sheriff will die, including the Mafioso. The Sheriff and the Bodyguard guarding the Mafioso will not die.

The Bodyguard can not prevent an attack caused on the Jailor if they jailed that certain target. So, if he jails a Serial Killer, but a BG protects him, it doesn't matter, the Jailor still dies.

However, this can confirm if the target he jailed is the Serial Killer/Werewolf, however, since it means the SK didn't visit the Jailor themselves.
