Christa Cachene's parents plead for help in Ranchlands homicide investigation

Christa Cachene'sdistraught family faced the press on Wednesday to plead for help in the investigation into the beating death of their daughter.

Calgary police are looking to speak to 18-year-old Isaiah Riel Rider, who they believe attended a party in Ranchlands beforeCachene's body was discovered later that day. Staff Sgt. Colin Chisholm refused to confirm whether Rider is a suspect.

Police believe she died "as a result of avicious beating" earlier that morning.

Rider is wanted on an Alberta-wide warrant for assault and a Canada-wide warrant for breach of conditions.

Cachene's father, Leslie, who discovered her body in the basement of the Ranchlands home around 5:30 p.m. on Sunday, broke down several times when talking about his daughter.

"I thought I was going to be the greatest grandpa and the greatest father she ever had," he said during the police press conference.

"It's difficult for me to understand that she's gone."

Cachene's mother, Nancy, said Cachene was planning to move to Vancouver to start a new life for her children.

"Christa was a strong, beautifulwoman," she said.

Both parents pleaded for anyone with information to come forward and help police in their investigation.

"We know that members of the aboriginal community attended the party on Saturday night and we urge you to come forward and talk to police," said her father.

Chisholm said some people who were at the party have been co-operative while others have "not been completely co-operative."

Police are looking for Rider in the Calgary area and in southern Alberta, said Chisholm. When asked if Rider was dangerous, Chisholm only said he's wanted on a warrant for assault and would not offer further information

Anyone with information about his whereabouts is asked to contact police by calling 403-266-1234 or Calgary Crime Stoppers.
