Framed!

You get a note from a friend to meet you at the park. Once there, a hologram appears, and the friend explains that she witnessed a murder that she's now being framed for. She needs your help to go around different parts of the park to collect evidence. Using a UV light, you capture 3 key pieces of evidence: fibers from a sweater, a handprint, and blood. Hopefully, it will be enough to clear your friend's name.
