Jacqueline Crazybull, a 43-year-old mother, died in a stabbing rampage in Calgary on July 11, 2007. She was one of five people attacked that night, and a single stab wound ended her life.

The Calgary Police Service has not made any arrests in her death to date. In October 2017, police announced Jacqueline's death is still actively being investigated.

Jacqueline "Jackie" Crazybull was born into a big Blackfoot family on Oct. 8, 1963. She was a middle child, a young girl who grew up mentoring those around her. Her sister describes her as a doer -- the kind of person who initiated family and community gatherings.

Sandra Manyfeathers says Jackie was a lot like their mother.

"My mother really showed us by example how to live a good life," she said.

Jackie's "take action" approach to life left an impact on her younger sister. A member of the Blood Tribe, Jackie was close to her culture and her family.

Manyfeathers recalls a day walking with Jackie through a wooded area looking for branches, which she needed for a particular Blackfoot game. When Manyfeathers tore a branch from a tree, her sister turned and looked at her.

"She didn't say anything, but I could tell she wasn't pleased. And I asked her 'What, why are you looking at me like that?'"

Manyfeathers recalled Jackie responding with, "Because [the tree is] living and you should respect all living things; all living beings are to be respected."

She said it was a profound realization.

"I always remember that, and to this day I have a lot of respect for living things and living beings," Manyfeathers said.

"And for her to be killed the way she was, it's just, she didn't deserve to be killed that way - for someone that had such value and such respect for life."

It was a summer day in July 2007 when Jackie's life was ended unexpectedly. It's perhaps not surprising to hear that when strangers pulled up in a vehicle asking for help, she responded.

It was Stampede time in Calgary. Jackie was living in the northeast part of the city and was working for her home community at the time. Manyfeathers said on that particular day, she had just gotten something to eat with her cousin.

"She got up and just went, and she was going to help them, and then they quickly stabbed her and then drove off," she said.

Crazybull was approached by 3 unknown black suspects and was attacked by them. She was rushed to hospital where she later died of her injuries. A single stab wound killed Jackie. She was 43.

"She was discarded on the street," said Manyfeathers.

It was described as a random stabbing rampage in the news. Four other people were attacked that day, but Jackie was the only person who died.

The young mother of two Lisa Leckie, 25, was found dead in her third-floor apartment on Southdale Road by her common-law husband, Derek, who was coming home from work shortly before 7 a.m. on March 24, 2009.

There is little information out there about Derek and Lisa's relationship. Derek did call police after discovering Lisa's body.

While still in high school, Lisa and Phil married. They split up more than a year before Lisa's murder, and the couple had one son together: 8-year-old Sean.

Her eight-month-old son was unharmed and found in his crib.

Over a decade later, investigators still haven't found her killer.

Investigators believe she was killed on the evening of March 23, 2009, or in the early morning hours of March 24, 2009. The autopsy revealed that she died as a result of asphyxiation.

Police revealed last year that a note written on a typewriter was left behind by her killer. The contents of the letter will not be released but investigators are hopeful that releasing the fact a typewriter was used will resonate with someone.

Head of the London police major crime section, Det. Sgt. Alex Krygsman, says the note indicates this was not a random act and that Lisa was targeted by someone she knew.

"We firmly believe that someone knows who killed this kind and loving mother, and we are appealing to that person's conscience."

Officers have also released surveillance footage pulled from a camera near Leckie's south London apartment. Police say the footage was recorded the night before Leckie's body was found.

A man described as 5-foot 11-inches and 200 pounds can be seen in the video. Investigators are looking to speak with him in regards to Leckie's murder.

Sean Leckie, who was eight at the time of his mother's murder, is pleading for someone to come forward.

"It affected everyone who had come into contact with her, to know that someone so special to us could be gone in an instant," said Leckie, in a video statement released by police.

Anyone with information can contact investigators with the Major Crime Section at 519-661-5674 or anonymously report to Crime Stoppers at 1-800-222-TIPS (8477) or online at www.londoncrimestoppers.com.
