In announcing the charges, county Prosecutor David Leyton said Tiarra died of bleeding from the lacerated liver.
Haynes was charged with first-degree murder, an open count of murder, first-degree child abuse and torture.
The first-degree murder charge carries an automatic penalty of life in prison without parole, while the torture and open murder charges carry up to life, and the child abuse charge up to 15 years’ imprisonment.
“My office will do everything it can to see that justice is served and the defendant is held accountable under the law,” Leyton said.
It wasn’t immediately clear Wednesday if Haynes has a lawyer. A phone message was left for a prosecutor’s spokesman Wednesday evening, and no one answered the phone at the county jail.
