Lawyers representing a Baton Rouge man who is charged with first-degree murder in the 2012 beating death of his 8-year-old son are claiming the East Baton Rouge Parish District Attorney's Office prosecutes men more harshly than women in child homicide cases. Michael Robertson's attorneys, who maintain his innocence in the death of Xzayvion Riley, accuse the office of "prosecution by stereotype, not be evidence." District Attorney Hillar Moore III disputes that characterization. State District Judge Don Johnson, who is presiding over the murder case, on Thursday denied a defense motion that asked him to order the District Attorney's Office to turn over information on the office's charging and plea negotiation history and practices in child homicide cases.

Robertson, 51, and Xzayvion's mother, Lavaughn Riley, 37, both are charged with first-degree murder in the boy's death. Moore's office announced in July it would not seek the death penalty in the case.
