A New York sheriff says Justin Sislo, who is accused of killing his parents before taking his own life, should have been imprisoned earlier because of his history of violence and repeated arrests. The case has raised questions about whether prior interventions, including occasions when his parents reportedly bailed him out, were sufficient to protect them.

The article reports that he had numerous previous arrests and an active protective order, although the supplied text does not provide further details about the earlier cases or the killings.
