Criminal homicide charges were filed Tuesday against two men accused of shaking their baby daughters to death.

Everado Mendoza, 21, of South Salt Lake is accused of shaking his 2-month-old girl on the afternoon of Nov. 18. She later died at the hospital, having suffered several broken bones and a broken back. The baby also had retinal hemorrhages and retinal detachment, indicating violent shaking had occurred.

Cleotis Shipman, 17, of Taylorsville is accused of causing brain damage severe enough to kill his 1-month-old baby girl the morning of Nov. 19.

Both fathers had been left with their infants for just a few hours.

Shipman had been living with the baby's mother and her family when the alleged abuse occurred. Prosecutors could pursue charges against him either of criminal homicide by creating a grave risk of death to another or of criminal homicide resulting from child abuse.

Police learned of the incident when a baby sitter came to Shipman's house and noticed the child was acting unwell. The baby sitter took the girl to the hospital, where she died.

Shipman was arrested Tuesday and is being held on $500,000 bail.

Mendoza is charged with criminal homicide resulting from child abuse. His charges, filed in 3rd District Court, replace charges of second-degree felony child abuse. Three counts of third-degree felony child endangerment, filed with the original charges, have not changed.

The charges against Mendoza come after his infant died at Primary Children's Medical Center. She was taken there after Mendoza noticed she had difficulty breathing the afternoon of Nov. 18, according to Tuesday's filing.

The girl died on Nov. 23. An autopsy was conducted by the Utah State Medical Examiner, after which new information was presented to the Salt Lake District Attorney's Office, according to South Salt Lake police.

When emergency room personnel found injuries on the girl indicating she had been violently shaken, Mendoza admitted to the police that he lost control while watching the girl.

Investigators served a search warrant on the place at which Mendoza was staying and found meth and drug paraphernalia within reach of three children, according to a police report.

Mendoza was being held Wednesday in the Salt Lake County Jail on $1 million bail on the homicide charge.
