Evidence
A taxi soon pulled up behind Emerson's car and a middle-aged man stepped out. Emerson and his driver walked up to greet the man. "You must be Albert Yang, I'm Jimmy Lai, Nina from dispatch said you took a client from The Peak to Royal Sunset Hotel around midnight last night. Is that correct?" Emerson's driver asked.
The man rubbed his eyes. He was sleeping when he received an urgent phone call, telling him that he was needed as a witness for a crime. At first, he brushed it off and said he couldn't remember a thing; he just wanted to sleep. After all, he worked the night shift and his clients were often entangled in random crimes that he had no idea about. He simply drove them; he had no idea who they were and what they were doing. Why did they always have to bother him?
