GUELPH, Ont. - Police say speed and icy road conditions caused the crash that claimed the life of a Guelph, Ont., constable.

Const. Jennifer Kovach died in March when her cruiser crashed into a city bus.

Police released the findings of their investigation into her death today.

The 26-year-old officer had been responding to a colleague's call for assistance at the time.

The bus Kovach's cruiser collided with had no passengers at the time and the bus driver had only minor injuries.

Police say Kovach lost control of her cruiser, crossed the centre line and hit the transit bus.

They also say she was not wearing her seatbelt at the time.

Kovach had joined the force four years earlier, fulfilling what relatives have said was her lifelong dream.
