(AP Photo/Laurent Cipriani, File) (Newser) – A clue has emerged in the brutal murder of three British family members as they vacationed in the French Alps last week. One of the survivors, a 7-year-old girl, reveals to police she saw only one killer, reports Sky News. Zainab al-Hilli, the daughter and granddaughter of the victims, could be the key witness to identifying the shooter and solving the massacre, say investigators. Zainab herself was bludgeoned and shot three times but pulled through after being put in a medically induced coma. Who did it? One theory being explored is a brotherly feud over money. Another motive could be corporate rivalry. Zainab's father was an engineer working on a secret contract for a European defense firm that specializes in satellite mapping.
