Claire Miller, the Manheim Township girl accused of fatally stabbing her sister early Monday, is one of two teenagers charged with homicide in Lancaster County. While Millerâs case is in its early stages, and little is known about the circumstances that led to the killing, a recent judgeâs ruling in the other case foreshadows what could happen with Millerâs case. Rahmir Hopkins was three weeks shy of his 15th birthday when police say he shot Luis A. Perez, 25, in the back as Perez was trying to get up off a sidewalk as two other people were kicking him.
