According to the police investigation, those three young men had managed to lure out that girl victim online. During dinner, they had covertly drugged her and thereafter led her to their car. They then drove to the lakeside's secluded area, intending to assault her.
This came to the attention of the blind girl, Li Jun, who happened to be strolling nearby. According to Li Jun, as she passed by the car, she overheard the conversation inside, which prompted her to call the police.
However, between the time Li Jun made the call and the arrival of the police, something occurred in the car that left its three occupants terrified, to the point they couldn't even muster the courage to run.
Li Jun told the police that after she'd phoned them, picked up a stone and threw it in the direction of the car, trying to pinpoint its location by sound to stop the men. She was worried about the victim.
What happened next was unknown, but she faintly heard the young men's screams of misery.
