Days after a routine injection to ease back pain, Donna Kruzich and a friend drove across the border to Canada in 2012 to see end-of-summer theater in Stratford, Ontario.
The 78-year-old Michigan woman suddenly became ill and returned home. By early October, she was dead.
"Most of the time she could not communicate with us. She was basically in a coma," son Michael Kruzich recalled. "We knew she had meningitis — but we didn't know how she got it."
