Two teenage boys who allegedly killed a young mother in an argument over a packet of cigarettes, posted pictures of themselves brandishing guns on Facebook hours after the crime.
Police are reportedly searching for 14-year-old Todavia Cleckley and Marcus Velasquez, who are on the run over the fatal shooting of 22-year-old Kayla Peterson, on Saturday [Dec 8] afternoon in Beaver Hills, Pennsylvania.
It is believed that the suspects, who officers have described as "armed and dangerous" posted the disturbing images on the social network themselves shortly before disappearing.
A third boy, 13-year-old Kyle Goosby, is already in custody and has been charged with conspiracy to commit homicide.
According to the Daily Mail the suspects followed the mother-of-one and her partner from a nearby store and asked them for cigarettes. When she refused and she told them to 'get a job', one teen pulled out a gun and fired a single shot.
Ms Peterson was flown to Allegheny General Hospital but died from the gunshot wound to the abdomen a few hours later.
If the teens are caught they will be tried as adults, meaning they could face up to life in prison.
