In the book Monster, by Walter Dean Myers, sixteen year old Steve Harmon is the protagonist. He is on trial for murder.
Let me make sure you understand what's going. Both you and this King character are on trial for felony murder
Mr. Evans and Mr. King were to enter the store and do the actual robbery. Another of the planners of this crime was to stand outside the drugstore and impede anyone chasing the robbers.
In the novel, Steve did not actually commit the murder. Instead, those that did commit the murder are stating that he was used as a look-out for the robbery of a store. Unfortunately, things got out of hand and the store owner, Alguinaldo Nesbitt, was shot and killed.
Therefore, Steve Harmon is on trail for being an accomplice to robbery and murder. He denies any involvement.
I don't know exactly when the robbery happened, but I know I wasn't in the drugstore that day.
The text of the novel shows Steve's perspective of his trial, ;shows his repeated denial of his involvement; and shows how he feels being placed in an atmosphere which finds him guilty from the beginning.
