In the book Monster by Walter Dean Myers, who is Steve, and what is the situation he is in?

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.
