Authorities say a Pennsylvania man was hosting a kindergarten party for his son and several other children when he was fatally shot, the AP reports. Witnesses tell police that a fight or rough play between the victim’s 6-year-old son and another 6-year-old led to an argument between adults at a Wednesday evening party in Hanover Township, near Wilkes-Barre. Authorities say the argument ended with 27-year-old Tremaine Jamison shooting 29-year-old Devon Brown in the head. Court records show troopers have charged Jamison with criminal homicide and possession of prohibited weapon. Police say Jamison lives in New York City and that authorities are searching for him.
