Lucas Arka and Leon immediately rushed to the local police station upon receiving news that evidence had been found at the crime scene where Grandma Maruna was killed, apart from Lucas's wallet. Lucas hoped that this piece of evidence would shed light on the identity of the real murderer of Grandma Maruna. They met with the Chief of Police and several detectives that Lucas had assigned to investigate the case.

"So, is it true that evidence has been found besides the wallet I had?" Lucas asked, prompting the Police Chief to nod. He then slid an object on his desk in front of Lucas. Lucas extended his hand and took the object, a large round button-like item that's usually attached to the waistband under a jacket. Lucas squinted his eyes, trying to remember if he had seen it before.

"Isn't this a symbol from a leather jacket?" Leon commented, making Lucas look at the object again. It was a large black button with the logo "LK." Suddenly, Lucas widened his eyes as he recognized the logo.
