TEENS IMPRISONED: In one of the Valley’s most brutally inexplicable crimes, three teen-age sisters from Northridge murdered a 62-year-old woman who befriended them and was stabbed to death. The youngest, 14, was sentenced Thursday to 15 years to life by a judge who did not buy a defense argument that she was coerced by her older sisters, already imprisoned (B5). . . . Under state law however, she will be freed on her 25th birthday.
