(1/25)
guy on street says that Snickers is safe.

(2/25)
Snickers says that homeless guy is a victim.

(3/25)
Homeless guy tells you that none of the following is a victim: diner worker, man on bike, Iris’ friend, Nurse Jill, Snickers, and Stan Sporcle. Those are the people that both Officer Tate and Sergeant White can see. Guy on street can only see two students, Adam Ford, and Stan Sporcle. He tells you that one of them is safe and the other is a victim. Since you now know that Stan Sporcle cannot be a victim, he must be safe and Adam Ford must be a victim.

(5/25)
If Officer Tate is adjacent to three victims, they must be Sergeant White, Laurie Strode, and paramedic. The others are ruled out by homeless guy. If store clerk is adjacent to three victims, they must be paramedic, Prof. Becks, and taxi driver. Rev. Stone is ruled out by Stan Sporcle. So whether Officer Tate or store clerk is adjacent to three victims, the paramedic is a victim.

(6/25)
Nurse Jill cannot be a victim according to homeless guy. This means Sergeant White is adjacent to zero or one victim, Officer Tate or nobody. If Sergeant White and paramedic are both adjacent to zero victims, then neither Officer Tate nor store clerk can be adjacent to three victims, as Adam Ford says one of them is. If Sergeant White and paramedic are both adjacent to one victim, then that victim is Officer Tate for both. Again, neither Officer Tate nor store clerk could be adjacent to three victims. So Sergeant White and paramedic are not adjacent to the same number of victims. This means, according to paramedic, that Adam is the only victim of the four students. Stan Sporcle says that Laurie Strode is not an accomplice; therefore she is safe.

(7/25)
With Laurie Strode being safe, Officer Tate cannot be adjacent to three victims, according to homeless guy. Therefore store clerk is adjacent to three victims. Stan Sporcle says Rev. Stone is not a victim, so Prof. Becks and taxi driver are victims.

(9/25)
Taxi driver tells you that guitarist and man on bike are not safe. Homeless guy told you that man on bike is not a victim; therefore he is an accomplice.

(10/25)
Rev. Stone is not a victim, according to Stan Sporcle. Iris Evans is not a victim, according to paramedic. Diner worker is not a victim, according to homeless guy. Therefore, according to man on bike, Mr. Andrews is a victim.

Since diner worker and Iris Evans are not victims (see above), diner guest 2 is adjacent to either one or two victims. This means, according to Prof. Becks, that diner guest 1 is also adjacent to one or two victims. Therefore, according to man on bike, just one of Detective Boyd/guitarist is a victim (if both, diner guest 1 would be adjacent to three victims) and Officer Tate is also a victim.

Since either Detective Boyd or guitarist is a victim according to man on bike, both diner guests are adjacent to two victims (diner guest 2 cannot be adjacent to a third). This means that diner guest 1 himself is a victim.

(13/25)
Take a look at Mr. Andrews. If the guitarist was an accomplice, that column still needs another victim, according to man on bike. So Detective Boyd would be a victim. If the guitarist is an accomplice, Sergeant White is not an accomplice. He also cannot be safe, according to Laurie Strode. So if the guitarist is an accomplice, Detective Boyd and Sergeant White are both victims. You already have Officer Tate as a victim, but according to diner guest 1, only two cops are victims. So guitarist is not an accomplice. Taxi driver says guitarist is not safe either, so guitarist is victim.

(14/25)
Since diner guest 2 cannot be adjacent to any more victims (homeless guy + paramedic) and since the diner guests are adjacent to the same number of victims (Prof. Becks), you know that Detective Boyd is not a victim. This means, according to diner guest 1, that Sergeant White is a victim.

(15/25)
Homeless guy told you that Iris’ friend and Nurse Jill are not victims. Now Sergeant White tells you they are not accomplices either; they are both safe.

(17/25)
Everyone the biker can see is filled in except Mrs. Myers and diner worker. So far man on bike cannot see any accomplice, but Officer Tate says he can see at least one. Iris’ friend says Mrs. Myers is not an accomplice, so diner worker is.

(18/25)
Diner worker says that three people have a different status. Since there are only three statuses, each one must be represented once. Neither Mrs. Myers nor Dr. Spencer can be an accomplice (Iris’ friend + Sergeant White), so Rev. Stone is an accomplice.

(19/25)
Since man on bike cannot see Rev. Stone, according to Officer Tate and Iris’ friend, there are no more accomplices. Detective Boyd and diner guest 2 are not victims according to Prof. Becks. They are safe. Iris Evans is not a victim according to paramedic. She is safe. Store Clerk is not safe, according to Laurie Strode. He/she is a victim.

(23/25)
Store clerk tells you that guitarist is adjacent to three victims. This means Dr. Spencer is a victim.

(24/25)
According to diner worker, Mrs. Myers must be safe.
