A 21-year-old man in the US allegedly launched a violent attack after a female jogger greeted him with a simple "good morning," according to police. The bizarre and unprovoked assault has drawn comparisons to horror-film killer Chucky due to the suspect's appearance, and the case highlights the unpredictable nature of random street violence against women exercising alone.

Police say the encounter began innocuously, with the woman offering a friendly greeting during her run, before the man reacted with sudden aggression. Details of the exact injuries and the specific charges he now faces were outlined by law enforcement, who took him into custody following the incident.
