Jacksonville gunman David Katz had a history of mental illness and was in treatment as early as 12-years-old, his parents' divorce records reveal.
The 24-year-old had been taking a number of medications, including an antipsychotic and antidepressant, and seeing psychiatrists over the years leading up to the mass shooting.
Police had been called to his family's home 26 times over 16 years - twice to deal with Katz after he had been in arguments with his mum Elizabeth
Katz had called police a day after turning 14 complaining that his mum kept taking his video games away as punishment, it was revealed.
