Calgary police are investigating a suspicious death in the southeast.

At around noon on Saturday police were approached by a neighbour who was concerned about the welfare of a woman.

Inside the apartment, in the 2800 block of 14 Avenue,  police found the woman dead.  It's believed she was in her 40's.

Police won't reveal what was found inside but say the death appears to be suspicious which prompted the homicide unit to be called in.

The downstairs neighbour, Gwen Karpinski, says at around 1:30 Saturday morning she heard crying and arguing.

Police went door-to-door speaking to neighbours.  A black chevy cobalt has also been towed away from the scene by investigators.

An autopsy is scheduled for Monday.  After that police will release more details.
