Calgary police are looking for the public’s help to unearth warm leads on cold cases.

The Calgary Police Homicide Unit and the Missing Persons Team are still pursuing information on three specific cases that could be solved with help from the public.

CPS Homicide Unit Staff Sergeant Sean Gregson said that no matter how much time passes, they try to find closure for victim families.  He said they’re hopeful that by recirculating the cases, people may be willing to come forward with information.

“No matter how much time has passed since an incident, we remain committed to finding closure for a victim’s family,” Gregson said in a prepared CPS media release.

“As time passes, allegiances can change and people may recall details they haven’t yet talked to police about. People may assume we are aware of certain details but we encourage anyone who has information to contact us, regardless of how insignificant they think their information is.”
