Caught part of this film on 5USA or 5* during December 2014. Appears to be a made for TV film (possibly canadian). Basic plot is as follows;
Blonde female cop/detective is investigating killings with her partner (and former lover/husband). Killer starts to phone the female cop prior to the killings as he has a past connection to her. Cop is conflicted about being a cop as her father who was also a cop, was a serial killer, whom she arrested. One of the murders occurs in an underground car park (a man) and the killer phones her while she is at the crime scene.
During the investigation she meets up with a guy (a high end TV / Electronics salesman) who she meets at her gym, many things occur which make him look like the killer. During following a lead on her new beau her partner and ex-husband is stabbed by the killer outside the local bar which they both used to visit.
The film ends with a rooftop shootout between the female cop and killer (who is her psychiatrist) after it is revealed a family member of his was killed by her father (possibly son/daughter).
Any Ideas?
