8 bottles of mineral water, 3 lives.
Just at the crime scene, Luke had already run three today.
Tom's house was also sealed off.
The technical team and the forensic doctor were short-staffed and hadn't arrived yet.
Luke, wearing gloves, examined the scene.
From the existing evidence, it was quite likely that young Tom was the poisoner, and poisoning required tools to carry out the act.
As long as the related tools and cyanide were found, it could prove the suspect's guilt in the poisoning.
Luke carefully observed the mineral water bottle, placing it in the sunlight. The bottle's exterior had an advertisement paper, and Luke faintly noticed there seemed to be a small black spot inside the advertisement paper.
Luke used scissors to cut open the advertisement paper and discovered the mineral water bottle had a bump the size of a pinhole, which was sealed with glue from the outside. It was difficult to discern unless observed closely.
