She said she thought she had turned the water off in the tub.
Holbert then made a telephone call to a friend and spent the next 15 minutes speaking with her.
She was distraught after looking on MySpace and discovering that her husband, Rocky Perez Sr., had fathered another child the same age as Isaiah.
Holbert, trying to learn more about the affair involving her estranged husband, who by then was in prison, talked to the friend about ways to sabotage the MySpace page.
While she was on the phone, the water that hadn't been turned off kept rising until Isaiah slipped under and drowned.
After hanging up, she found Isaiah floating in the tub facedown.
On Oct. 3, 2008, a grand jury indicted Holbert on a charge of child abuse, negligently causing death.
She pleaded guilty to a reduced charge of reckless manslaughter in March 2009 and was sentenced two months later to four years of intensive probation.
A state child fatality review said the family was known to social services because Perez Sr. was violent toward Holbert. It found no policy violations by Morgan County human services.
