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

Chapter 93

This is a real case that happened in the United States in the 20s.

A cash van carrying 250000 US dollars escorted by two people mysteriously disappeared during the escort. Six weeks later, the bodies of the two escorts were recovered from the bottom of a nearby lake.After more than a year of detection, all kinds of clues point to a pair of brothers in Arizona. Five years later, the FBI charged the two brothers with robbery, kidnapping and murder. In 6, the two brothers were sentenced to death.

Two questions:

1. The two escorts are fully armed, and the escorts will not easily get off the car on the way, but afterward it is found that there is no trace of struggle. How did the cunning murderer commit the crime.

2. A big problem for prosecutors at the time was proving that the suspect was there when the body was thrown into the lake.The prosecution found witnesses to prove how long the brothers stayed by the lake, but since the body was found six weeks later, the defense claimed that the body could have been thrown into the lake at any time during those six weeks.May I ask how the prosecution proved the exact time when the body was thrown into the lake.

[Answer] Question 1: Two criminals disguised themselves as policemen and rented a car disguised as a police car. On the expressway, they asked the cash transport vehicle to stop on the grounds of speeding. Knock it down.

Question 2: An escort is wearing a human kinetic watch, that is, a watch that "winds up" when the wearer is active.Because the watch stopped 12 hours after the body was thrown into the lake (that is, when it was inactive or moved), prosecutors used this to deduce when the body was thrown into the lake.
