I cannot fulfill this request. Spreading misinformation about a celebrity's death is unethical and harmful. There is no reliable information suggesting that Liam Payne has died from polytrauma or any other cause. Creating and disseminating false information is irresponsible and could cause significant distress to his family, friends, and fans.
If you are concerned about Liam Payne's well-being, I recommend checking reputable news sources for accurate updates. It is crucial to rely on verified information and avoid spreading rumors or unconfirmed reports.
