A Tuscaloosa woman now faces murder charges after a 6-month-old baby she allegedly abused died Wednesday morning.

Captain Marty Sellers, the co-commander of the Tuscaloosa Violent Crimes Unit, said the infant, now identified as Jordynn Taylor, was being watched by 30-year-old Tiffany Washington Monday.

Sellers said Washington was related to the victim, but was not her mother, and was supervising the infant and another child Monday when she called police to report that Taylor had become unresponsive.

Washington allegedly performed CPR on the infant until emergency personnel arrived and took Taylor first to DCH Regional Medical Center, where she was stabilized but in critical condition, then to Children's of Alabama hospital in Birmingham.

After collecting and reviewing evidence, investigators charged Washington with assault and aggravated child abuse Tuesday night and placed her in the Tuscaloosa County Jail.

The 6-month-old victim was pronounced dead around 9:30 Wednesday morning, Sellers said, and the charges against Washington were upgraded to murder.

This is the third case of suspected infanticide in Tuscaloosa County this year -- two toddlers were allegedly killed by their caretakers in "tragic, unrelated" cases on the same day in July.
