Become serial: cashier killer

Who is the killer of Mary White?

Linda Clark and Eric Adams were at the funeral park, staying just few meters away from the bereaved of Mary White and watching the funeral procession. None of the suspects were there, except the husband Bruce White. It was a moment full of sorrow and sadness. The most frustrating moment for the police officers was the fact that the murderer was still out there.

One week later, a week full of interrogations and clues that leaded to a dead end, officers Clark and Adams were still far away from uncovering the mystery of the murder of Mary White. Detective Linda Clark was at the police department when one of her colleagues said:

- We received an assignment for a murder in the industrial area. A cashier was killed.
- Wait, what? - said the surprised detective - Could you repeat?
- There was a murder in the industrial area. Woman was killed, a cashier. Me and my partner received the assignment.
- Could you call me, when you arrive at the crime since. We are still working on a murder of a cashier with Adams, but in other district.
- OK Linda, I'll do it.
