Just days before a two-month-old Lucas Ruiz was scheduled for surgery he began having seizures and police believe his own father is to blame.

On October 16, the son of Cesar Ruiz, 19, and Erika Wigstrom was admitted to Ochsner Hospital in Jefferson Parish, Louisiana because he was having trouble breathing.

Lucas was diagnosed with an unnamed illness and scheduled for surgery on October 31. Saturday night, the parents went home to shower and grab a few things, and that’s when police say Ruiz grabbed the bottle of rum that was in the freezer. Wigstrom later told police that while they were home,  she went to grab something from the freezer and remembered seeing the bottle, but when she went back a bit later, the bottle was gone.

The parents returned to the hospital Sunday morning and some time later, Lucas began having seizures. Tests revealed the child’s blood-alcohol content (BAC) was .289. Doctors say the brain is still growing until the a person reaches their 20s, so alcohol can have permanent negative effects on a child’s brain.

The hospital called police who then spoke with Wigstrom who told them about the rum that had been in the freezer. Detectives then spoke with Ruiz who initially claimed he had no idea what happened to the rum nor did he have any explanation for his son’s BAC.

Some time later, Ruiz confessed, saying he waited until Wigstrom left the baby’s room before pouring the rum directly into Lucas’ feeding tube.

Ruiz claims he was trying to relieve his son’s suffering, but did not intend to kill him.

Lucas is said to be in stable condition and Ruiz has been charged with attempted first-degree murder.
