Baffling Targets

Exploration Stage: Shaded Patio
From: Mr. Black
Description: The relationship between William and Avocado is becoming clearer. We have to be very careful or we will put him on his guard. By the way, one of the guests found a target with a picture stuck on it on the patio. Can you help me find it?
Completed: Is that a picture of your friend Jacob? That's an odd target. It could be a prank in bad taste or evidence that Jacob was somehow at odds with Avocado. I don't have an answer yet, but Jacob must be involved.
