York City Police are still searching for suspected killer Alexis Cado-Suero, 15, of York. York Daily Record In the Saturday afternoon sun, women labored over a bleeding teen as he lay in a York courtyard. One clasped her hands together and pushed down on his sternum over and over, compressing it, while another whooshed air into his lungs with her mouth. A third held his hand, praying to the Lord not to take him. The women, residents of the Historic Newton Square, had heard the staccato of shots just before 3 p.m. and saw a collapsed Tyree Smart, 16, of York. The island of a neighborhood, with its well-manicured homes and gardens, and where the breeze funnels through just right, might have violence and death all around it, but never in it, according to residents.
