Marcus Salter

Marcus Salter is the half-brother of Ben Salter, who owned his own tailors shop and who was murdered.

Marcus works at night as a taxi driver because he has photophobia which means he experiences crippling pain/migraine due to exposure to bright light.

After scaring a girl in his cab, he became a suspect in his half-brother's murder and those of his employees. In his interview with Chandler and Miles at the station he says that he thought about killing his half-brother but someone beat him to it. He also say's his heart is dead.
