Naturally, there weren't any surveillance cameras in these old apartment buildings.
The only security measure the apartment building had was an elderly lady who watched the main entrance. She was about 60 years old and still looked quite spirited despite her age.
Luke mused that this granny here definitely wasn't as terrifying as Granny Lucy.
Selina went over and showed the granny her badge wallet with the new badge on it. On one side of the wallet was a police badge while on the other side was an ID card; they were most commonly issued to officers dressed in civilian clothes.
The granny remained calm and wasn't shocked to see the police. When she heard that they wanted the key for the apartment where the murder had happened, she fished out a key from behind her. "This is the only copy I have. Remember to return it when you're done."
Selina thanked her with a smile.
The two then headed up the stairs to the third floor.
