CALGARY – The 60-year-old Calgary man convicted of killing his five-year-old grandson has been sentenced to nine years in prison.

Last month, Court of Queen's Bench Justice Richard Neufeld found Allan Perdomo Lopez guilty of manslaughter for the death of Emilio Perdomo.

"While the exact details of the fatal assault will remain unknown, you admitted to your God to having killed Emilio and you did so against a history of child abuse within your own household," said Neufeld addressing Perdomo Lopez directly in the courtroom.

The five-year-old’s mother sent her son to Canada from Mexico in 2015 with hopes of a better life. But the little boy died five months later from a severe brain injury.

Emilio was unconscious when he arrived at the Alberta Children’s Hospital in July 2015. He died eight days later.

Perdomo Lopez was charged a year after the boy's death.

During the trial, court heard Emilio suffered physical abuse at the hands of his grandfather, who considered him an 'ungrateful demon.' The judge found Emilio’s injuries were inflicted, not accidental.

A police wiretap recording from the family minivan was presented as evidence of Perdomo Lopez tearfully praying in Spanish. An English translation of the recording submitted in court said Perdomo Lopez was asking for forgiveness, saying he didn’t want to kill that child.

Both sides were suggesting significant prison time for Perdomo. The Crown argued for a 12 to 15 year prison term, saying Perdomo Lopez was in a position of trust.

The defence recommended six to eight years, arguing there wasn’t enough evidence Perdomo Lopez was responsible for bruises and scars all over Emilio’s body.

But the judge said even if Perdomo Lopez didn’t cause those other injuries, he knew about them and did nothing to stop them.

Perdomo was out on bail until Friday, when he was taken into custody after he was sentenced.

Perdomo’s wife Carolina Perdomo was also in the courtroom when the sentence was delivered.

She was initially charged in Emilio’s death, but the Crown stayed the manslaughter charge earlier this year.

Prosecutors have one year to revive those charges if new information comes to light.
