“A French filmmaker whose documentary about a violent street gang in El Salvador provoked controversy earlier this year has been found shot in the head. The body of Christian Poveda, 52, was discovered in a car in Tonacatepeque, a poor rural area 10 miles outside the capital San Salvador. … La Vida Loca (Crazy Life), Poveda’s latest film, focused on the hopeless and brutal lives of various fantastically tattooed members of [the] Mara 18 [gang].”
