Carlos Daniel Pascual Richiez, 19, was shot and killed in Allentown, Pennsylvania on October 10, 2017, after a dispute over text messages escalated. The conflict began when a 25-year-old man took a young boy’s cellphone; a heated argument followed when the man later tried to return the device and one person was struck with a pistol. The 25-year-old then left in an SUV. Pascual Richiez pursued that SUV in a separate vehicle to obtain its license plate number. The pursuit ended when his vehicle rear-ended the SUV; the SUV driver exited and shot Pascual Richiez in the head. He was taken to a nearby hospital and died shortly afterward.

Authorities charged a 25-year-old man with criminal homicide in the days after the shooting. Investigators said the violent outcome might have been prevented if police had been contacted earlier in the dispute. Does anyone have information about the events leading up to the confrontation or the people involved?
