Three months after Haverhill Police Chief Alan R. DeNaro asked for a social worker to help police, his wish was granted Friday after two high-profile incidents of violence which may have mental health causes. When he appeared before the City Council in December, DeNaro cited suicides, drug overdoses, domestic violence, runaways and other situations where a social worker would be helpful in defusing immediate problems and getting help for individuals as well. Last week, DeNaro renewed his call for help.
