A young mother was senselessly murdered by three teens in western Pennsylvania after she told them to “get a job” and stop roaming the streets when they asked her fiancée for a cigarette, police say. Beaver Falls police have charged 14-year-olds Todavia Cleckley and Marcus Velasquez and 13-year-old Kyle Goosby Jr. with criminal homicide and other charges in Saturday’s shooting of 22-year-old Kayla Peterson. She was shot at about 3:30 p.m. that day and died in a Pittsburgh hospital two hours later.
