Fourth-grade teacher Irma Garcia was killed in her Texas classroom on Tuesday, massacred along with her co-teacher and 19 students. Two days later, a family member says her brokenhearted husband died.
The motive for the massacre — the nation's deadliest school shooting since Newtown, Conn., almost a decade ago — remained under investigation, with authorities saying the 18-year-old gunman had no known criminal or mental health history.
