Sian Amaya Cartagena, 18, was fatally wounded by a gunshot on October 2, 2023, and died of her injuries on October 4, 2023, at a local hospital. Her death was ruled a homicide by the Lehigh County Coroner’s Office and was counted as the 16th homicide in Allentown that year.

Emergency services responded to a West Green Street residence after a 911 call. Police arrived around 5:30 a.m. and found Cartagena in a second-floor bedroom with life-threatening injuries. Twenty-one-year-old Ethan Nicholas Bastien, who had placed the call, was at the scene and was taken into custody; he was initially charged with attempted homicide and later faced upgraded criminal homicide charges and held without bail.

Cartagena was the eldest of five children; her mother said she had many goals and plans for her future. Is there anyone who knew Sian or who has information about what happened that morning who can help investigators?
