What we know about Edward Downey, charged in killing of Taliyah Marsman and her mother

The Calgary man charged with two counts of first-degree murder in the deaths of Sara Baillie and her five-year-old daughter, Taliyah Marsman, has an extensive criminal record, investigators say.

Edward Downey, 46, who also goes by the name Edward Simmonds, was charged after Taliyah's body was found on a rural property east of Chestermere late Thursday, ending a three-day Amber Alert. Earlier in the week, her mother was found slain in a home's basement suite that she shared with the child.

Police say the accused is known to both victims and Taliyah's father, Colin Marsman — Baillie's estranged common-law partner.

"I don't know the level of trust there would have been there, but he is definitely known to Sara and Taliyah," said Insp. Don Coleman.

Downey is the only suspect at this point, and police said he has offered limited co-operation. Police say they have yet to find a motive for the killings.

Downey was ordered to have no contact with the girl's father. Both men have ties to Halifax. He will remain in custody until his next court appearance on Wednesday.

North Preston's Finest gang connections

CBC News has confirmed Downey is connected to the North Preston's Finest (NPF) gang. It also goes by the Willis Crew. NPF members recruits girls in the Maritimes, forcing them into prostitution in cities across Canada, according to Ontario police.

Downey shares this gang connection with Taliyah's father and Baillie's most recent boyfriend.

Calgary police were chasing these connections early in the investigation.

Downey previously convicted on drug, weapons and pimping offences

CBC News has learned Downey had a lengthy criminal record, dating back at least 25 years, that includes convictions for cocaine trafficking, weapons offences and pimping-related charges.

Court records show Edward Delten Downey was convicted in 2008 of trafficking cocaine and possession of an unauthorized firearm. He was sentenced to four years. He was also sentenced to 18 months in jail for pimping in 1998.

Downey and a woman, who owned a residence together in Coventry Hills, defaulted on their mortgage, and in 2011 were sued by the bank for $126,000 — the amount still owing on the house.

Police are currently searching Downey's home in Calgary's northeast community of Skyview Ranch.

Mother believed to be target

Police say they currently believe Baillie, 34, was the target, but her cause of death is not being released.

She has been described as a hard-working single mom.

"Sara was a beautiful young woman who was single-handedly pretty much raising her daughter, and we love her and we miss her," Scott Hamilton said of his niece.

"We have lost a niece, a sister, a daughter and a mother ... God rest her soul," he said.

Baillie's aunt, Marilynne Hamilton, said the mother-daughter relationship was unique.

"Taliyah worships Sara," Marilynne said through tears on Tuesday.

The uncle of Colin Marsman says the family is heartbroken.

"The last couple of days have been very trying," said Barry Marsman.

"These heinous events have caused us unimaginable pain.... Our lives will never be the same, and it's really hard to put in words the grief and shock that we feel."

'Our hearts are broken at the tragic end'

Many people across the country have also expressed shock and sadness.

"On behalf of all Canadians, I want to express our condolences to the families and the people of Calgary for the devastating loss of Taliyah and her mom, Sara," said Prime Minister Justin Trudeau as he appeared at the Calgary Stampede on Friday morning.

"I know there were a lot of hearts broken when the news came out, and there were so many volunteers and police services involved in trying to help a terrible situation that we all need to take a moment to send our love and hearts out to Taliyah and Sara's family."

NDP Leader Tom Mulcair also tweeted his thoughts.

Premier Rachel Notley expressed in a statement her deepest gratitude to members of the Calgary police, to those who heeded the Amber Alert and spread the word through social media, and others who joined in the search for Taliyah.

"Our hearts are broken at the tragic end of the search for little Taliyah. I know everyone prayed that she be found and returned to her family, to grow up as happy as she appeared in the photographs provided through the media."

Calgary Mayor Naheed Nenshi simply said: "Our hearts are all broken."

Makeshift memorial grows

Calgarians continue to stop at the home where Taliyah lived in the northwest community of Panorama Hills to pay their respects.

Despite pouring rain at times on Friday, flowers, candles and stuffed animals continue to be placed in front of the house.

Irena Lucardie and her 12-year-old daughter, Kiahna, stopped to bring flowers and say a prayer.

"It's just so unbelievable. Not only because it's our community, but it's just an innocent child. I just can't imagine what would go through the mind of somebody to do that," said Irena Lucardie.

Kiahna, who attended the same dance studio as Taliyah, said: "She was always so happy and joyful."

Nicole May worked at a restaurant with Baillie before Taliyah was born.

"It's really just disgusting," she said with tears in her eyes. "I didn't know how someone could do that to a family."
