Ricardo Tobia, 71, was found dead at his home on the 500 block of Kirk Avenue in Pittsburgh on July 7, 2018. Tobia was a longtime voice instructor at Point Park University. Tobia’s dog was also killed in the incident.

Investigators recovered blood-stained shoes and other evidence linking Martin to the scene. The text reports Martin had a history of mental illness and that, in the days before the killing, his mother said he had been catatonic and behaving erratically; he was involuntarily committed after Tobia’s body was discovered. The case raises questions about how severe mental illness is identified and managed before violence occurs.

If anyone knew Tobia, his routine, or observed unusual behavior from the roommate in the neighborhood before July 7, 2018, please share what is known.
