NASHVILLE, Tenn. - Metro police are searching for the aunt of a baby who died.
Police said Marisol Alvarado will be charged with murder. Alvarado promised the mother she'd take care of the child.
But, police said the aunt caused serious injuries, which led to the baby's death less than two months later.
In early June, a Davidson County Sheriff's deputy sat outside a delivery room at Nashville General Hospital.
The deputy waited as 32-year-old jail inmate Ana Granados gave birth to Mario Plafex.
Granados had to go back to jail, so she gave Mario to her sister-in-law Marisol Alvarado.
"The police department immediately began trying to get to the bottom of what occurred," said Don Aaron, a Metro police spokesman
Aaron said the department received a call from doctors when Alvarado took Mario to Southern Hills Hospital on July 16. The child's injuries -- broken bones and a head injury - caused doctors to transfer the baby to Monroe Carell Jr. Children's Hospital at Vanderbilt the same day.
Police said Alvarado admitted to hurting the baby.
"She threw him up into the air in a prone position and let him land back onto the crib. This was done more than once," Aaron said.
Alvarado also told police she shook the baby several times to stop him from crying.
Police officers wanted to charge her with aggravated child abuse and neglect, but when they got to the apartment Alvarado had taken her own three children and left. Mario died in the hospital two weeks later.
Police said with the mother watching, doctors pulled the plug on Mario on July 30. Afterwards, the Medical Examiners Office conducted an autopsy. The doctors said the baby had broken ribs, a broken left foot and a severe head injury.
Police said when they find Alvarado not only will she face abuse charges but also the charge of murder.
"This is a person who is now, we believe, fleeing the police department, fleeing law enforcement. We think that she knows she's wanted," Aaron said.
Police believe Alvarado is still in Nashville.
They think she's trying to blend in with the Latino and Hispanic community. Alvarado's three children are supposed to be with their grandfather, while police investigate these allegations.
If anyone sees Alvarado, they should call Crime Stoppers. That number is 74-Crime.
If the information leads to her arrest, the caller could earn up to $1,000.
