When Michael Lajun Green met up with his ex-girlfriend—and the mother of his two young children—at a room in the Sportsmen's Lodge in Studio City, they were attempting to reconcile after a period of discord and estrangement, Los Angeles police said. But early Monday, the couple began to argue. The confrontation turned physical, investigators said, and shortly before 5 a.m. Green pulled out a handgun and shot his ex-girlfriend in the head before fleeing with the children.
