A Bronx father who admitted to killing his son and attempting to kill his daughter was sentenced Thursday to 20 years to life behind bars.

As New 12 previously reported, Leonardo Espinal fed his 7-year-old daughter Mia and 5-year-old son Stewart pizza laced with rat poison after learning his ex-wife was seeing someone new. He then ate the pizza himself, placed his son in the bathtub and called their mother to say it was her fault.

Stewart Espinal was discovered drowned in the family's bathtub, but his sister survived.

"Mia will have to live the rest of her life with the horrific memory that her own father caused in attempting to kill her," said Assistant District Attorney Jill Starishevsky.

Espinal did not speak at the sentencing.
