At first, the hearse driver was merely creepy in the pilot, but after Chandra meets with him, we know our initial suspicions were there for a reason.
Why It Could Be Him:
- His line about smoking to Andrea could be perceived as threatening.
- The security footage at the gas station shows both cars leaving at the same time, and it looks like he follows Andrea and Naz out of the gas station.
- When Chandra tracks down the hearse driver at his "office" (where he paints the nails of a corpse wile talking to her), he says of Andrea: "I saw her for the destroyer she was and I did not like that." He also talks about how you have to strike first with women like her, calls Naz a plaything of hers, and then quotes the Bible passage about Samson and Delilah. Could he, as a religious fanatic, have killed Andrea in a fervent, religion-motivated murder?
Why It Might Not Be Him:
- He could have just gone on his own way after the gas station.
