Crime scene: 162 mystery solving puzzles to find out who the murderer is

Chapter 72 The Delayed Detection
Harlequin took a report, looked at it for a while, and said to the sheriff: "According to the autopsy report, Mrs. Tried was clubbed to death in her kitchen two days ago. The lonely The old woman has been living for many years in a dilapidated manor on top of a certain hill, almost cut off from the outside world. What kind of murder do you think this is?"

"Oh, damn it! I got an anonymous call at 4 o'clock yesterday morning, reporting that she had been murdered, but I thought it was another prank, so I haven't started investigating until today." Sheriff Monaghan said embarrassingly.

"Then let's go and have a look at the scene now." The sheriff led Harlequin to the front porch of the manor and said, "Because the stores in the city don't set up telephone appointments for delivery, and have to write orders, the old lady rarely even calls. Hit. Aside from a milkman and a postman who are regulars, the only visitors are the boys who deliver the groceries once a week."

Harlequin stared at two stacks of newspapers and an empty feeding bottle on the front porch, then sat in a rocking chair and asked, "Who last saw Mrs. Tread?"

"Maybe Mrs. Carson," said the sheriff, "she said she saw the old lady getting milk on the front porch when she drove by the other morning."

"It is said that Mrs. Tread is very rich. She has hidden at least 5 yuan in the manor. I think this must be murder. The murderer's methods are vicious, but we have not found any clues yet."

"It should be said that apart from that anonymous phone call, we have no other clues."

Harlequin corrected: "The murderer really didn't expect you to delay so long before starting to solve it!"

Who does Harlequin suspect of being the murderer?
[Answer] Harlequin suspects that the milkman is the murderer. It was the milkman who made the anonymous call. He thought that the police would start to solve the problem soon after answering the phone, so he didn't have to deliver the milk again, because there were two newspapers on the scene, but Not even a bottle of milk.
