As soon as the inspector entered the office, he received an alarm call from the swimming center, saying that someone in the swimming center had died mysteriously, and asked the inspector to hurry over to see what was going on. After receiving the alarm, the inspector rushed to the swimming center.

The inspector came to the swimming center and saw Williams lying on the ground with a lot of white foam coming out of his mouth. The medical examiner then made an assessment of Williams. Soon the results of the identification came out, and it was determined that Williams had died of poisoning, an hour earlier. So the inspector asked his girlfriend, Dani, who was swimming with Williams.

Dani recalled: "Williams made an appointment to come to the swimming center with me last week, and I knew he had an arm injury, so I said I couldn't come, but he insisted on coming. Who knew that there were so many people who came to swim today, and one of the people in the back of the line almost tripped Williams, but thanks to me helping him, he didn't fall. Then we went into the hall and the hall manager gave Williams a bottle of juice because he was the guest of honor here, and I thought there was something wrong with the hall manager who gave the juice to Williams to drink. Subsequently, the forensic doctor tested williams' juice and found no problems. In addition, no problems were found with the food eaten by the deceased during his lifetime.

Why did Williams die of poisoning?
