Toronto Police believe that the parents of a boy found dead in a suitcase in Jamaica are the same couple that left a baby in a Toronto stairwell almost four years ago.

According to various media reports, Stephanie Warren, 34, and her husband Alfanso Warren, are in a Jamaican prison after police found the decomposing body of Jeshurun, their 2-year-old son, in a suitcase a week ago.

The couple moved to Jamaica in 2009 after being found guilty in the abandonment of their infant in Toronto in January, 2008.

Baby Angelica was found in a cold stairwell of a plaza in the Leslie Street and Finch Avenue area. The temperature was about -14 Celsius when a passerby noticed her on the floor.

A security camera caught a man driving up to the door of the stairwell in a Ford Escort. The video taken from the camera showed him carrying a bundle in his arms.

The parents were arrested in Kitchener, Ont. a number of months later.

Toronto police said they contacted authorities in Jamaica earlier this week to apprise them of the link between the two cases.

"Toronto police have contacted Jamaican authorities about our involvement about the two people in Jamaica and our investigation," Toronto Police Staff Sgt. Brian Gottschalk told CTVNews.ca. "We will be working closely with them on it."

Reports say the couple was arrested earlier this week after neighbours said that they had not seen the boy for months.

Police found the badly decomposed body of the boy in a suitcase.

Although a pathologist confirmed the boy was not a victim of foul play, the parents could face charges for concealing the body. Charges for breaching the Child Care Protection Act are also possible.

The couple was originally charged in Ontario with abandoning a child, failing to provide the necessities of life, assault causing bodily harm, and criminal negligence causing bodily harm in relation to Angelica's case.

The father was sentenced to 11 months and given time served after he pleaded guilty to abandoning a child and three counts of failing to provide the necessities of life. He was given two years probation.

The mother was fined under the province's Family Services Act.
