Calgary police are asking for help from the public in locating an 18-year-old man who may have information in connection to Sunday’s death of Christa Cachene in a northwest townhouse.

On Sunday afternoon, officers responded to the home on Ranchlands Bay Northwest after the body of 26-year-old Christa Cachene was located by Christa's father Leslie as he was returning his grandchildren to their mother.

"The father discovered Cachene in the basement of her home where she had been viciously beaten,”said CPS Staff Sergeant Colin Chisholm.

“We know that a party was hosted at the residence on Saturday evening and that many individuals were in attendance. We have spoken with a number of individuals that had attended the party and are looking to speak to a man we believe also attended the party.”

Police believe Isaiah Riel Rider of Calgary, who is wanted on unrelated warrants, was one of approximately 8 people who attended the Saturday night party, in the hours prior to the grisly discovery.

Rider is described as:

An Aboriginal male

Approximately 188 cm (6’2”) tall

Weighing 70 kg (155 lbs)

Having black hair and brown eyes

The arrest warrants issued for Rider are in connection with an assault (Alberta-wide warrant) and a breach of a conditional sentence order (Canada-wide warrant).

Police believe the murder occurred shorly after midnight.

According to her parents, Christa Cachene had plans to relocate to Vancouver for a fresh start with her children.

On Wednesday afternoon, Christa's family issued a plea for information in connection with the death of the single mother who was a 'strong, beautiful woman'.

“We know that members of the Aboriginal community attended the party at Christa’s on Sunday night and we urge you to come forward and speak with the police,” said Christa's mother Nancy.

“Please come forward if you have information about my girl’s murder,” said Leslie.

Anyone with information about Rider’s current whereabouts or the Ranchlands death is asked to contact the Calgary Police Service, 403-266-1234, or Crime Stoppers.
