Chapter 166 Holy Blood

Susan didn't answer immediately but pointed to the data on the projector, "The suspect Darcy bought 10 liters of blood plasma in January, and the amount increased gradually in February, March, and April. Why did the purchase volume drop back to 10 liters of blood plasma in May?"

Luke said, "That's something I was also wondering about, and the blood bank manager wasn't very clear either.

My guess is either he found a new source for purchasing blood plasma, or a new competitor emerged."

The deputy chief asked, "If Darcy is related to the death of the female singer Angela, then what is his motive?"

Luke replied, "Angela was the most famous vampire-themed singer with numerous crazy vampire fans. Is it possible that Darcy wanted to use Angela for promotion to expand his blood plasma sales territory?

In this aspect, Angela would definitely be the best spokesperson.
