Jiangcheng Radio host Lin Wan hosts a late-night emotional program called "Soul Night Talk" every night. This month, she started getting calls from the same man. The man spoke in a low, calm voice for only three minutes at a time, describing how he planned a murder. The first three times, the police thought it was a prank. It wasn't until the fourth night that the first murder described by the man actually happened - the circumstances of the deceased and the details of the crime were exactly the same as what he described on the radio.
