So Rosie Larsen died not only because she overheard Jamie's Indian casino conspiracy talk, but because Aunt Terry was in the car and would rather let what she thought was some random girl drown in a lake than lose out on the chance that Mr. Ames would leave his wife. And before that, Darren Richmond got paralyzed because he had the horrible timing to have been attempting suicide at the exact moment Rosie was killed, making it difficult for a man in his position to offer the cops a convincing alibi. And before that, Bennet Ahmed got beaten half to death(*) because he also couldn't tell the cops the truth because he was busy trying to save some other, unrelated girl from being ritually circumcised the night that Rosie died.
