How does Stevenson build suspicion about Hyde in chapter 4? (PEE)

In this chapter, a respected member of London society, Sir Danvers Carew, is murdered. A maid sitting by her window in the very early morning hours witnesses the story recounts the event. She gazes out her window, romantically feeling at one with the world, when she sees an aged man with white hair walking along a nearby path. She watches as he meets another, smaller man, whom she recognizes as Mr. Hyde. Suddenly, Mr. Hyde brakes out in anger and attacks the white haired man, beating him to death with a cane. The maid faints upon witnessing such horror. When she awakes a few hours later, she immediately calls the police, who find the victim's body. On his person, the victim carried a purse, some gold, and a letter addressed to Mr. Utterson. Subsequently, the police contact Mr. Utterson who identifies the victim as Sir Danvers Carew, a member of Parliament. Upon learning the identity of the attacker, Mr. Utterson takes the police chief to Mr. Hyde's home. The police find the rooms in Hyde's home ransacked. Clothes strewn everywhere, half of the cane used to murder Danvers Carew is in one of the corners, and the remnants of a burned checkbook lie on one of the tables. The police soon discover that Mr. Hyde has disappeared. He cannot be found anywhere, and they are unable to find any trace of his past. Moreover, those who have seen him are unable to describe him in detail, but generally agree on his evil appearance.
