Representations/ different editing (own stills)

A homeless person gets litter thrown at them (as can be seen on the floor).

                                                                 So, the homeless person takes revenge and shots a person.

                                                             A friend mourns the deceased person (they can be seen crying).

The friend confronts the homeless person with a hidden agenda (behind the back).

The friend shots the homeless person out of anger.

  The killer disposes of the body in a dumpster. 

                                                         The killer closes the door to the dumpsters (looking suspiciously).

And disposes the evidence in a hedge.
